Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

Generally, in order to provide services to other electronic devices, some electronic devices may be configured with a server, and the other electronic device may have a client that can establish a connection with the server. Wherein, before the client uses the service provided by the server, the client first needs to obtain the service provided by the server. For example, in communication based on the GATT (Generic Attribute Profile) protocol, the GATT client needs to initiate a service discovery process to the GATT server to discover the service data in the GATT server, so as to obtain the services that the GATT server can provide.

However, the inventor found in the research that there is still a problem that the efficiency needs to be improved in the related service data acquisition method. For example, the inventors found that after the client establishes a connection with the server, if the client detects that no credit relationship has been established with the established server, the client will initiate a service data discovery process to obtain all service data. That is to say, in the absence of a credit relationship, the client will acquire all the service data from the server once during each service data acquisition process, which will result in a long time-consuming service data acquisition process. , thereby affecting the efficiency.

Therefore, in order to improve the above problems, the inventor proposes a data acquisition method, device, electronic device and storage medium provided in the present application, which identifies the first service data specified in the server by obtaining from the wireless data corresponding to the server. After the identification, it is further determined whether the first service data obtained from the server based on the specified identification has been pre-stored locally, and if so, directly obtained from the server based on the specified identification. service data (second service data) other than the first service data, so that the second service data and the local first service data are used as the acquired service data of the server.

Therefore, through the above method, when the server distinguishes the service data into the first service data and the second service data, the client can obtain the first service data from the server in advance to store locally, and then make subsequent In the process of obtaining the service data corresponding to the server each time, the second service data can be obtained only through the specified identifier in the wireless data corresponding to the server, thereby reducing the need to obtain the second service data from the server during each service data acquisition process. The amount of data for data acquisition in the server improves the efficiency of obtaining service data from the server.

An application scenario involved in the embodiment of the present application is firstly introduced below.

As shown in FIG. 1 , an application scenario involved in the embodiment of the present application includes an electronic device 100 and an electronic device 200 . Wherein, the electronic device 100 runs a server, and the electronic device 200 runs a client. Wherein, the client in the electronic device 200 may be a GATT client, and correspondingly, the server in the electronic device 100 may be a GATT server.

Furthermore, the types of the first electronic device and the second electronic device shown in FIG. 1 are only exemplary. For example, as shown in FIG. 2 , the second electronic device can also be a wireless earphone 210 in addition to the smart phone shown in FIG. 1 . Furthermore, in addition to the smart phone shown in FIG. 1 , the first electronic device can also be a tablet computer or a computer. Furthermore, besides the devices shown in FIG. 1 and FIG. 2 , the second electronic device can also be devices such as smart bracelets and smart watches.

Various embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Please refer to Figure 3, a data acquisition method provided by the embodiment of the present application is applied to the client, and the method includes:

S110: Obtain a specified identifier from the wireless data corresponding to the server, where the specified identifier is used to identify first service data in the server, where the first service data is constant service data.

Wherein, the server can send wireless data after running. Moreover, the wireless data sent by the server is different at different stages. Wherein, the wireless data sent by the server may be broadcast data after the server starts running but before establishing a connection with the client. Correspondingly, if the server sends broadcast data, the server may add the specified identifier to the broadcast data for sending. For example, it is assumed that the server is a GATT server and the client is a GATT client. After the GATT server is running, it can trigger the electronic device to send BLE (Bluetooh Low Energy) broadcast data. In addition, the BLE broadcast data may carry a specified identifier. Then, after the electronic device where the GATT client is located scans the BLE broadcast data, the GATT client can extract the specified identifier from the BLE broadcast data.

Furthermore, after the client establishes a connection with the server, the server may send wireless data based on the connection established with the client, then the wireless data sent after the connection is established may be wireless data carrying service information. Wherein, the business data may be data transmitted during the mutual business interaction between the client and the server.

Wherein, it should be noted that the service data in the server can be understood as data related to the service provided by the server, or can be understood as data used to describe the provided service. Optionally, the service data may include a service (service name), a feature corresponding to the service, and a feature descriptor corresponding to the feature. Among them, the feature can be used to describe the function of the corresponding service, and the feature descriptor can be used to describe how the corresponding function is used and whether it is scalable. The services, features, and feature descriptors included in the service data in the server are respectively identified. For example, in the GATT server, the service, feature, and feature descriptor each correspond to a handle as their respective identifiers. Moreover, in some cases, the identifiers corresponding to the services, features, and feature descriptors are arranged in a certain order. Exemplarily, as shown in FIG. 4 , the server includes service 1 , service 2 and service 3 . Wherein, Service 1 corresponds to Feature 1, and Feature 1 corresponds to Feature Descriptor 1. Service 2 corresponds to Feature 2, and Feature 2 corresponds to Feature Descriptor 2. Service 3 corresponds to feature 3, and feature 3 corresponds to feature descriptor 3. The ID corresponding to service 1 is 0x0001, the ID corresponding to feature 1 is 0x0002, and the ID corresponding to feature descriptor 1 is 0x0003. The ID corresponding to service 2 is 0x0004, the ID corresponding to feature 2 is 0x0005, and the ID corresponding to feature descriptor 2 is 0x0006. The identifier corresponding to service 3 is 0x0007, the identifier corresponding to feature 3 is 0x0008, and the identifier corresponding to feature descriptor 3 is 0x0009.

It should be noted that the number of services included in the server shown in FIG. 4 is only exemplary, and the server may include fewer or more services than those shown in FIG. 4 . For example, only Service 1 and Service 2 may be included, or services other than Service 1, Service 2, and Service 3 may be included. Similarly, the number of features corresponding to each service may not be limited to one as shown in FIG. 4 , for example, there may be multiple features corresponding to a service. Furthermore, the style of the logo shown in FIG. 4 is only exemplary, and the logo in this embodiment of the present application may also have other styles. For example, the storage location of the service data at the server end may be directly used as the corresponding identifier. It should be noted that, as a method, the storage addresses in the server are sequentially sorted adjacently, so the storage address of the service data is used as an identifier, and the service data can still be sorted based on the storage address.

Among the service data included in the server, part of the service data may be fixed, and the part of the service data that is fixed may be classified based on their corresponding identifiers. For example, the service data may be divided into first service data and second service data by corresponding identifiers of the service data. Wherein, the first service data represents fixed service data, and the second service data represents service data that may change.

Optionally, the specified identifier may include a start identifier and an end identifier, wherein the start identifier is used to identify the start position of the first service data, and the end identifier is used to represent the end position of the first service data. As shown in FIG. 4, based on the situation shown in FIG. 4, if the determined first service data includes service 2, feature 2, feature descriptor 2, service 3, feature 3, and feature descriptor 3, then the corresponding The specified identifiers include 0x0004 and 0x0009, where 0x0004 is the start identifier and 0x0009 is the end identifier. Optionally, the first service data can be determined starting from the service data with the highest corresponding identifier among the service data included in the server, and the first service data is determined sequentially along the order of identifiers from small to large until the first detection of The service data is not constant, and the identifier of the previous service data that is detected for the first time as the service data that is not constant is used as the designated identifier. For example, please refer to Figure 4 again, where the identifier 0x0001 corresponding to service 1 is the highest-ranked identifier, and the fixed service data will be determined sequentially starting from 0x0001. If the first detected non-fixed service data is service 3, then it may be determined that the first service data includes service data corresponding to the identifier 0x0001, the identifier 0x0002, the identifier 0x0003, the identifier 0x0004, the identifier 0x0005, and the identifier 0x0006. Thus, 0x0006 will be used as the specified identifier.

Furthermore, it should be noted that the fixed service data shown in the embodiment of the present application can be understood as service data that does not change within a specified time period on the device where the server is located. Wherein, the specified time period may be a life cycle of the device where the server is located, or a certain operation period of the device where the server is located. Among them, the life cycle can be understood as the time when the device can be used. For example, if a device is used for two years, then the life cycle of the device is two years. Wherein, the operation period may be a period set by the user, for example, the user may set one week as one operation period, or one month as one operation period.

S120: If the first service data previously obtained from the server based on the specified identifier is locally stored, acquire second service data from the server based on the specified identifier, and the second service data is the Service data other than the first service data in the server.

It should be noted that, in this embodiment of the application, after the client obtains the specified identifier from the wireless data for the first time, it can determine which specific service data in the server are the first service data according to the specified identifier. Furthermore, the first service data is stored locally on the client.

Correspondingly, each time the client obtains the specified identifier from the wireless data sent by the server, it can first determine whether the first service data identified by the acquired specified identifier has been stored this time, and if it has already been stored, then The second service data can be directly obtained from the server based on the specified identifier.

As a manner, after obtaining the specified identifier from the wireless data corresponding to the server, it further includes: if the first service data obtained from the server based on the specified identifier is not locally stored, then from the server Acquire the service data corresponding to the server; store the first service data in the service data corresponding to the server locally.

S130: Use the second service data and the local first service data as the acquired service data of the server.

It should be noted that, in the embodiment of this application, the wireless data received by the client as shown in the foregoing content may be broadcast data, or it may be wireless data sent by the server received after establishing a connection with the server . No matter what stage of data the wireless data refers to, the purpose of establishing a connection between the client and the server is to discover the service data corresponding to the server, and then perform subsequent operations based on the obtained service data corresponding to the server. operate. Then, after obtaining the second service data returned by the server, the client can combine the second service data with the first service data, and then use the combined service data as the acquired service data corresponding to the server. .

Wherein, combining the second service data and the first service data may be understood as sorting the second service data and the first service data in a predetermined order. It can be understood that all service data in the server are arranged in a certain order. However, in this embodiment of the application, the client will separately store the first service data in the service data corresponding to the server locally, so that the first service data and the second service data may be obtained separately, then it can By uniformly sorting the second service data and the first service data in a predetermined order, the order of the service data finally acquired by the client is consistent with the original order in the server. Wherein, the predetermined order is the arrangement order of the service data in the server.

In the data acquisition method provided by this embodiment, after obtaining the designated identifier of the first service data in the identified server from the wireless data corresponding to the server, it is further determined whether the specified identifier based on the designated identifier has been pre-stored locally. The first service data obtained by the server, if any, directly obtain the service data (second service data) in the server other than the first service data (second service data) from the server based on the specified identifier, so that all The second service data and the local first service data are used as the acquired service data of the server.

Please refer to Figure 5, a data acquisition method provided by the embodiment of the present application is applied to the client, and the method includes:

S210: Acquire a specified identifier from the wireless data corresponding to the server, where the specified identifier is used to identify first service data in the server, where the first service data is constant service data.

S220: If the first service data previously obtained from the server based on the specified identifier is locally stored, determine a service data query range based on the specified identifier, and the service data query range is a range corresponding to the second service data.

Wherein, as can be known from the foregoing description of the embodiments, in the embodiments of the present application, there may be multiple implementation manners for specifying the identifier. For the specified identifiers in different implementations, the corresponding determined data query scope may also be different.

As a method, the designated identifier is the last identifier in the designated identifier interval, the start identifier of the designated identifier interval is the first identifier in the server end, and the designated identifier interval is the The interval where the identifier corresponding to the first service data is located; the determining the service data query range based on the specified identifier includes: taking the range where the identifiers sorted after the specified identifier is located as the service data query range. That is to say, in the case that the first service data is counted from the first identifier, the designated identifier is the last identifier among the identifiers corresponding to the service data included in the first service data. Moreover, in the case that the identifiers corresponding to the service data are sorted from small to large, the designated identifier is the largest identifier among the identifiers corresponding to the service data included in the first service data. For example, please refer to FIG. 4 again. In this manner, if the designated identifier is 0x0006, then the determined service data query range is from 0x0007 to the last identifier.

As another way, if the specified identifier includes the start identifier and the end identifier, then the client will use the range from the first identifier on the server to the start identifier, and the range after the end identifier as the service data query scope. For example, please refer to Figure 4 again. In this way, if the start identifier is 0x0004 and the end identifier is 0x0006, then the determined service data query range will include 0x0001 (the first identifier) to 0x0003, and include 0x0007 after the range.

S230: Trigger the server to search for service data based on the service data query range, so as to obtain the found second service data.

S240: Use the second service data and the local first service data as the acquired service data of the server.

The data acquisition method provided by this embodiment enables the client to obtain the first service data from the server in advance when the server distinguishes the service data into the first service data and the second service The data is stored locally, so that in the subsequent process of obtaining the service data corresponding to the server, the second service data can be obtained only through the specified identifier in the wireless data corresponding to the server, thereby reducing the number of times The amount of data that needs to be obtained from the server in the process of obtaining service data improves the efficiency of obtaining service data from the server. Moreover, in this embodiment, the client can further determine the service data query range according to the specified identifier, so that the server can directly obtain the service data based on the service data query range determined by the client, further improving the efficiency.

Please refer to Figure 6, a data acquisition method provided by the embodiment of the present application is applied to the client, and the method includes:

S310: Acquire a specified identifier from the wireless data corresponding to the server, where the specified identifier is used to identify first service data in the server, where the first service data is constant service data.

S320: Obtain the device identifier of the device where the server is located from the wireless data.

Wherein, the device identifier is information used to identify the uniqueness of the device. In the embodiment of this application, there may be multiple implementation manners for the device identification.

As a manner, the device identification can be implemented through the network address corresponding to the device. In this way, the network address of the device can be used as the device identifier of the device. For example, if the device where the server is located sends wireless data through Bluetooth communication. Then the wireless data sent based on the Bluetooth communication will carry the Bluetooth address of the device, and then the client can use the Bluetooth address carried in the wireless data as the device identifier of the device. Wherein, when the Bluetooth address is used as the device identifier, the Bluetooth address is a public address, so that the Bluetooth address of the device is fixed.

As another way, the device identifier can be a random number generated based on a specified protocol, and the random number generated each time can be different, so that the device identifiers corresponding to different devices can be unique. When the server sends wireless data every time, it can add the random number as the device identification to the wireless data sent, so that the client receiving the wireless data can know which server the current wireless data is from sent by the end.

Then, in the case that the device identifier can be implemented in multiple ways, the client can obtain the device identifier in a predetermined way.

Optionally, if the predetermined method configured by the client is to obtain the network address carried in the wireless data as the device identifier, then after the client obtains the wireless data sent by the server, it can directly perform The extraction of the network address is used as the device identification of the device where the server is located. Optionally, if the predetermined method configured by the client is to obtain the random number carried in the wireless data as the device identification, then after the client obtains the wireless data sent by the server, it can directly perform The extraction of the random number is used as the device identification of the device where the server is located.

Furthermore, the client may also acquire the device identifier in an adaptive manner. It should be noted that when different servers identify their own devices, they may adopt different identification methods. For example, although the wireless data sent by the device may carry a network address, some devices use a random network address (random network address), which may make the network addresses of different devices the same. In this case, there is no way for the network address to uniquely identify the device.

As a way, in the process of obtaining the device identification, the client can first detect the type of network address used in the wireless data; if it detects that the network address is a fixed type of network address, it will directly use the obtained network address as the sending The device identification of the device for the wireless data; if it is detected that the network address is a random type of network address, then further detect whether the wireless data carries a random number generated based on a specified protocol; if a random number generated based on a specified protocol is detected , then use the random number generated based on the specified protocol as the device identifier of the device sending the wireless data. If no random number generated based on the specified protocol is detected, all service data is directly obtained from the server as service data corresponding to the server.

It should be noted that, in the embodiment of the present application, after obtaining the first service data from the server, the client may store the device identifier and the first service data correspondingly.

S330: Detect whether service data corresponding to the device identifier is locally stored.

As described above, when storing the first service data, the client may store the device identifier and the first service data correspondingly. Then, the client detects whether the service data corresponding to the device identifier is stored locally. It can actually be understood that the client determines whether there is the first service data obtained from the server locally. Moreover, the first service data is service data identified by a specified identifier in the wireless data where the device identifier is located.

S340: If the service data corresponding to the device identifier is not stored locally, determine that the first service data previously obtained from the server based on the specified identifier is not stored locally.

S350: If the service data corresponding to the device identifier is stored locally, determine that the first service data previously obtained from the server based on the specified identifier is stored locally.

S360: If the first service data previously obtained from the server based on the specified identifier is locally stored, obtain second service data from the server based on the specified identifier, and the second service data is the Service data other than the first service data in the server.

S370: Use the second service data and the local first service data as the acquired service data of the server.

The data acquisition method provided by this embodiment enables the client to obtain the first service data from the server in advance when the server distinguishes the service data into the first service data and the second service The data is stored locally, so that in the subsequent process of obtaining the service data corresponding to the server, the second service data can be obtained only through the specified identifier in the wireless data corresponding to the server, thereby reducing the number of times The amount of data that needs to be obtained from the server in the process of obtaining service data improves the efficiency of obtaining service data from the server. Moreover, in the process of storing the first service data in this embodiment, the first service data and the device identifier of the device where the server is located will be stored correspondingly, so that when it is determined that the service data corresponding to the device identifier is stored , it can be directly determined that the first service data of the server is stored.

Please refer to Figure 7, a data acquisition method provided by the embodiment of the present application is applied to the client, and the method includes:

S410: Obtain a specified identifier from the wireless data corresponding to the server, where the specified identifier is used to identify first service data in the server, where the first service data is constant service data.

S420: Check whether the designated identifier acquired from the wireless data is consistent with the designated identifier stored locally.

It should be noted that the first service data and the second service data are distinguished by a designated identifier in the server. Then, after the client acquires the first service data from the server based on the specified identifier in the wireless data for the first time, it can store the specified identifier based on which the first service data is obtained and the acquired first service data correspondingly locally. Then it means that the first service data stored locally corresponds to the designated identifier. Then the client can check whether the specified identifier currently obtained from the wireless data is consistent with the specified identifier stored locally after each time the specified identifier is obtained from the wireless data sent by the server. If they are consistent, it indicates that the server The first service data is still unchanged, and then the client can determine that the first service data obtained from the server based on the specified identifier currently obtained from the wireless data has actually been stored locally.

Exemplarily, if the specified identifier currently obtained from wireless data is identifier 1, and the specified identifier obtained locally by the client is also identifier 1, then the client can determine the specified identifier obtained from wireless data and the locally stored The specified identifiers are consistent. If the designated identifier currently obtained from the wireless data is identifier 2, and the designated identifier obtained locally by the client is also identifier 2, then the client can determine that the designated identifier obtained from the wireless data and the designated identifier stored locally are inconsistent.

Furthermore, it should be noted that the client may have established connections with various servers, and the designated identifiers corresponding to different servers may be the same. Then in this way, the client can store the specified identifier and the device identifier (the device identifier of the device where the server is located) correspondingly, so as to distinguish the specified identifiers corresponding to different servers. Exemplarily, the specified identifier stored locally by the client may be as shown in the following table.

IDID	指定标识designated logo	设备标识Equipment Identity
11	标识1Logo 1	设备1equipment 1
22	标识2Logo 2	设备2device 2
33	标识3Logo 3	设备3device 3

Wherein, if the specified identifier currently obtained from the wireless data is identifier 2 and the device identifier is device 2, then the client can query the data in which the specified identifier is identifier 2 and the device identifier is device 2 in the specified identifier stored locally (that is, the data corresponding to the ID being 2), the client determines that the specified identifier obtained from the wireless data is consistent with the specified identifier stored locally. If the specified identifier currently obtained from the wireless data is identifier 2 and the device identifier is device 1, it is determined that the specified identifier obtained from the wireless data is not consistent with the specified identifier stored locally. Moreover, in this case, it can be further determined that the first service data corresponding to the server in device 1 has actually changed, so that the specified identifier used to identify the first service data has also changed, and, after determining that the server In the case that the corresponding first service data has actually changed, all the service data corresponding to the server needs to be reacquired from the server.

S440: If not, determine that the first service data previously acquired from the server based on the specified identifier is not locally stored.

S450: If they are consistent, determine that the first service data previously obtained from the server based on the specified identifier is locally stored.

S460: If the first service data previously obtained from the server based on the specified identifier is locally stored, acquire second service data from the server based on the specified identifier, and the second service data is the Service data other than the first service data in the server.

S470: Use the second service data and the local first service data as the acquired service data of the server.

The data acquisition method provided by this embodiment enables the client to obtain the first service data from the server in advance when the server distinguishes the service data into the first service data and the second service The data is stored locally, so that in the subsequent process of obtaining the service data corresponding to the server, the second service data can be obtained only through the specified identifier in the wireless data corresponding to the server, thereby reducing the number of times The amount of data that needs to be obtained from the server in the process of obtaining service data improves the efficiency of obtaining service data from the server. Moreover, in this embodiment, in the process of storing the first service data locally, the specified identifier on which the first service data is obtained will also be stored locally, so that in the subsequent process of obtaining the service data corresponding to the server Among them, whether the first service data is pre-stored locally can be quickly determined by detecting whether the specified identifier obtained from the wireless data is stored locally, which is beneficial to improving the efficiency of obtaining service data.

Please refer to Figure 8, a data acquisition method provided by the embodiment of the present application is applied to the server, and the method includes:

S510: Send wireless data carrying a specified identifier, where the specified identifier is used to identify first service data in the server, where the first service data is constant service data.

As a manner, the wireless data is broadcast data, and the sending the wireless data carrying the specified identifier includes: sending the broadcast data carrying the specified identifier.

S520: Obtain second service data from the server in response to an acquisition request sent by the client and corresponding to the specified identifier, where the acquisition request is determined locally stored by the client in advance based on the specified identifier. The first service data obtained from the server is sent later.

S530: Send the second service data to the client, so that the client uses the second service data and the local first service data as the acquired service data of the server.

As a manner, the obtaining the second service data from the server in response to the obtaining request sent by the client corresponding to the specified identifier includes: responding to the obtaining request corresponding to the specified identifier sent by the client request, obtaining the service data query range from the acquisition request, and querying the service data corresponding to the service data query range as the second service data in the server.

It should be noted that, for specific detailed explanations corresponding to the steps in this embodiment, reference may be made to relevant content in the foregoing embodiments.

In the data acquisition method provided by this embodiment, the server adds the specified identifier used to identify the first service data in the server to the wireless data sent, so that the client can pass the data sent by the server. The wireless data obtained by the designated identifier, so that in the case that the client pre-stores the first service data obtained based on the designated identifier, it can only obtain the service data from the server in the process of obtaining the entire service data of the server. The second service data is enough. This further reduces the amount of data that needs to be acquired from the server in each service data acquisition process, and improves the efficiency of acquiring service data from the server.

It should be noted that, in the embodiment of this application, before the client obtains the specified identifier from the wireless data corresponding to the server, the client can first detect whether a credit relationship has been established with the server that transmits the wireless data. After establishing a credit relationship, you can directly acquire services in the server according to the service acquisition method corresponding to the established credit relationship. If the credit relationship is not established, the subsequent acquisition of the specified identifier from the corresponding wireless data of the server may be performed. Wherein, if a trust relationship has been established between the client and the server, it means that identity authentication has been performed between the client and the server.

Next, an example is used to introduce the process of an actual scenario involved in the embodiment of the present application. As shown in Figure 9, the process shown in Figure 9 includes:

S610: The GATT client obtains the broadcast data sent by the GATT server, and obtains a specified identifier from it.

S620: The GATT client establishes a connection with the GATT server.

S630: The GATT client detects whether it is the first time to establish a connection with the server.

Among them, the GATT client may have multiple ways to detect whether it is the first time to establish a connection with the server. For example, the method of detecting whether the service data corresponding to the device identifier of the device where the GATT server is located can be detected locally in the foregoing embodiments. Correspondingly, if the service data corresponding to the device identifier is stored locally, it is determined that it is not the first A connection, otherwise, if the service data corresponding to the device identification is not stored locally, it is determined to be the first connection. For another example, it is also possible to detect whether the specified identifier obtained from the broadcast data is consistent with the specified identifier stored locally. Correspondingly, if it is detected that the specified identifier obtained from the broadcast data is consistent with the specified identifier stored locally, Then it is determined that it is not the first connection. On the contrary, if it is detected that the specified identifier obtained from the broadcast data is consistent with the specified identifier stored locally, or if the specified identifier has not been stored locally, it is determined that it is the first connection.

S640: If it is the first connection, the GATT client triggers the service search from the first service data in all the service data of the server.

Wherein, the service data in the server may be arranged in a certain order. For example, as shown in FIG. 4 , the service data whose corresponding identifier is 0x0001 is the first service data among all the service data of the server. Then, when the GATT client determines that it is the first time to establish a connection with the GATT server, it will trigger to start searching for services from the service data identified as 0x0001 in the GATT server.

S641: The GATT client locally stores the first service data among the searched service data.

When the GATT client determines that it is the first time to establish a connection with the GATT server, the GATT client will actually search all the service data in the GATT server to find all the services in the GATT server data. then for convenience

S650: If it is not the first connection, the GATT client triggers to read the first service data locally.

S651: The GATT client triggers a service search starting from the first service data after the specified identifier, so as to obtain the second service data.

It should be noted that, in the embodiment shown in FIG. 9 , the designated identifier represents the identifier corresponding to the last service data in the manner of performing fixed data detection starting from the first service data. It can also be understood that the specified identifier is an identifier with the largest corresponding identifier in the fixed service data. Wherein, the ordering of the service data is equivalent to the ordering of the identifiers corresponding to the service data. For example, please refer to Figure 4, if the fixed service data is determined starting from 0x0001, and the determined fixed service data includes service 1, feature 1, feature descriptor 1, service 2, feature 2, and feature description character 2. Then, among the determined and constant service data, the one with the largest corresponding identifier is 0x0006, and the determined specified identifier is 0x0006. Then after the GATT client determines to establish a connection with the GATT server for the first time, the first service data stored locally will include service 1, feature 1, feature descriptor 1, service 2, feature 2, and feature descriptor 2 . Then after the subsequent connection is not established for the first time, the service data search will start from 0x0007.

Wherein, the processing manner after obtaining the first service data and the second service data can refer to the contents in the foregoing embodiments.
