Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

In general, in order to provide services to another electronic device, a service terminal may be configured in the electronic device, and a client terminal that may establish a connection with the service terminal is established in the other electronic device. Before the client uses the service provided in the server, the client needs to acquire the service provided in the server. For example, in communications based on the GATT (Generic Attribute Profile) protocol, the GATT client needs to initiate a service discovery procedure to the GATT server to discover service data in the GATT server, so as to obtain services that can be provided by the GATT server.

However, the inventors have found in the study that there is still a problem in that efficiency is to be improved in the related service data acquisition manner. For example, the inventor finds that if the client detects that no trust relationship is established between the client and the server connected after the client establishes a connection with the server, the client initiates a service data discovery procedure to obtain all service data in the server. That is, under the condition that the trust relationship is not established, in each service data acquisition process, the client acquires all the service data in the service end once, so that the service data acquisition process consumes longer time, and further the efficiency is affected.

Therefore, in order to improve the above-mentioned problem, the inventor proposes a data acquisition method, a device, an electronic apparatus and a storage medium provided by the present application, where after acquiring a first service data specified identifier in an identifier server from wireless data corresponding to the server, it is further determined whether first service data acquired from the server based on the specified identifier is already stored locally in advance, and if so, service data (second service data) other than the first service data in the server is acquired from the server directly based on the specified identifier, so that the second service data and the local first service data are used as acquired service data of the server.

An application scenario according to an embodiment of the present application will be described first.

As shown in fig. 1, an application scenario according to an embodiment of the present application includes an electronic device 100 and an electronic device 200. The electronic device 100 is provided with a server, and the electronic device 200 is provided with a client. The client in the electronic device 200 may be a GATT client, and the corresponding server in the electronic device 100 may be a GATT server.

Again, the types of first and second electronic devices shown in fig. 1 are merely exemplary. For example, as shown in fig. 2, the second electronic device may be a wireless headset 210 in addition to the smartphone shown in fig. 1. Furthermore, the first electronic device may be a tablet computer, a computer, or other devices besides the smart phone shown in fig. 1. The second electronic device may be a device such as a smart band or a smart watch, in addition to the devices shown in fig. 1 and 2.

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

Referring to fig. 3, a data acquisition method provided in an embodiment of the present application is applied to a client, and the method includes:

s110: and acquiring a specified identifier from wireless data corresponding to a server, wherein the specified identifier is used for identifying first service data in the server, and the first service data is fixed service data.

The server side can send wireless data after running. And, the wireless data sent by the server is different in different stages. After the server starts to operate, the wireless data sent by the server may be broadcast data before connection with the client is established. Correspondingly, if the service end sends the broadcast data, the service end can add the appointed identification into the broadcast data for sending. For example, taking a server as a GATT server, a client as a GATT client as an example. After the GATT server runs, the electronic device can be triggered to send BLE (Bluetooh Low Energy) broadcast data. And, 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 may extract the specified identifier from the BLE broadcast data.

Furthermore, after the connection between the client and the server is established, the server may send wireless data based on the connection established with the client, and then the wireless data sent after the connection is established may be wireless data carrying service information. The service data may be data transmitted during a process of performing service interaction between the client and the server.

Here, the service data in the service side may be understood as data related to a service provided by the service side, or may be understood as data for describing the provided service. Optionally, the service data may include a service (name of the service), a feature corresponding to the service, and a feature descriptor corresponding to the feature. Wherein, the feature can be used to describe the functions of the corresponding service, and the feature descriptor can be used to describe how the corresponding functions are used and whether the corresponding functions have extensibility, etc. The service, the feature and the feature descriptor included in the service data in the service end are respectively corresponding to the identification. For example, in the GATT server, the service, the feature, and the feature descriptor are each associated with a handle as their respective identities. In some cases, the identifiers corresponding to the services, features, and feature descriptors are arranged in a certain order. For example, as shown in fig. 4, the service end includes a service 1, a service 2, and a service 3. Wherein, service 1 corresponds to feature 1, and feature 1 corresponds to feature descriptor 1. Service 2 corresponds to feature 2, feature 2 corresponds to feature descriptor 2. Service 3 corresponds to feature 3 and feature 3 corresponds to feature descriptor 3. Service 1 corresponds to an identification of 0x0001, feature 1 corresponds to an identification of 0x0002, and feature descriptor 1 corresponds to an identification of 0x0003. Service 2 corresponds to an identifier of 0x0004, feature 2 corresponds to an identifier of 0x0005, and feature descriptor 2 corresponds to an identifier of 0x0006. Service 3 corresponds to an identification of 0x0007, feature 3 corresponds to an identification of 0x0008, and feature descriptor 3 corresponds to an identification of 0x0009.

It should be noted that the number of services included in the service side shown in fig. 4 is only exemplary, and fewer or more services than those shown in fig. 4 may be included in the service side. For example, only the service 1 and the service 2 may be included, and services other than the service 1, the service 2, and the service 3 may be included. Similarly, the number of features corresponding to each service may be not limited to only 1 shown in fig. 4, and for example, there may be a plurality of features corresponding to the service. Moreover, the patterns of the identifiers shown in fig. 4 are also merely exemplary, and other patterns are also possible for the identifiers of the embodiments of the present application. For example, the storage location of the service data on the server may be directly used as the corresponding identifier. It should be noted that, as a way, the storage addresses in the server are sequenced adjacently in sequence, and the service data can still be sequenced based on the storage addresses by using the storage addresses of the service data as the identifier.

Among the service data included in the service end, part of the service data may be fixed, and the fixed part of the service data may be divided based on the corresponding identifier. For example, the service data may be divided into the first service data and the second service data by the service data correspondence identification. The first service data represents the service data which is fixed and unchanged, and the second service data represents the service data which can possibly change.

Alternatively, the specified identifier may include a start identifier and an end identifier, where the start identifier is used to identify a start position of the first service data, and the end identifier is used to characterize an end position of the first service data. As shown in fig. 4, if the determined first service data includes service 2, feature descriptor 2, service 3, feature 3, and feature descriptor 3 based on the case shown in fig. 4, the corresponding specified identifier includes 0x0004 and 0x0009, where 0x0004 is a start identifier and 0x0009 is a stop identifier. Optionally, the first service data may be determined from the service data included in the service end and the service data with the front corresponding identifier is sequentially determined from the small identifier to the large identifier, until the service data that is not fixed is detected for the first time, and then the identifier of the previous service data that is not fixed is used as the specified identifier. For example, referring to fig. 4 again, the identifier 0x0001 corresponding to the service 1 is the identifier with the top ranking, and then the fixed service data is determined sequentially from the identifier 0x0001, and if the first detected service data is not the service 3, the first service data may be determined to include the service data corresponding to the identifiers 0x0001, 0x0002, 0x0003, 0x0004, 0x0005 and 0x 0006. Thus 0x0006 would be the designation.

Furthermore, it should be noted that the fixed service data shown in the embodiments of the present application may be understood as service data that does not change in a specified time period when the device where the server is located. The specified time period may be a life cycle of the device where the server is located, or may be a certain operation cycle of the device where the server is located. A lifecycle, among other things, is understood as the time that a device can be used. For example, a device may be used for two years, and the life cycle of the device is then two years. The operation cycle may be a cycle set by the user, for example, the user may set one week as one operation cycle, or may set one month as one operation cycle.

S120: and if the first service data which is acquired from the service end based on the specified identification in advance is stored locally, acquiring second service data from the service end based on the specified identification, wherein the second service data is the service data except the first service data in the service end.

It should be noted that, in the embodiment of the present application, after the client obtains the specified identifier from the wireless data for the first time, it may be determined, according to the specified identifier, which service data is the first service data in the server, and then the first service data is stored locally in the client.

Correspondingly, after the client acquires the specified identifier from the wireless data sent by the server, whether the first service data identified by the acquired specified identifier is stored at this time can be determined first, and if so, the second service data can be acquired from the server directly based on the specified identifier.

As a way, the obtaining the specified identifier from the wireless data corresponding to the server further includes: if the first service data acquired from the server based on the specified identifier is not stored locally, acquiring the service data corresponding to the server from the server; and storing the first service data in the service data corresponding to the service end locally.

S130: and taking the second service data and the local first service data as the acquired service data of the service end.

In this embodiment of the present application, the wireless data received by the client may be broadcast data, or may be wireless data sent by the server received after connection is established between the client and the server. The purpose of establishing connection between the client and the server is to find service data corresponding to the server, and then to perform subsequent operations according to the obtained service data corresponding to the server. After the client acquires the second service data returned by the server, the client can combine the second service data with the first service data, and then the combined service data is used as the service data corresponding to the acquired server.

Wherein combining the second service data and the first service data is understood as ordering the second service data and the first service data in a unified and established order. It will be appreciated that all service data in the server is arranged in a certain order. However, in the embodiment of the present application, the client may store the first service data in the service data corresponding to the server separately, so that the first service data and the second service data may be acquired respectively, and then the second service data and the first service data may be uniformly ordered according to a predetermined order, so that the order of the service data finally acquired by the client and the original order in the server are consistent. The predetermined sequence is the arrangement sequence of the service data in the server.

According to the data acquisition method provided by the embodiment, after the first service data specified identifier in the identifier service end is acquired from the wireless data corresponding to the service end, whether the first service data acquired from the service end based on the specified identifier is stored in advance is further determined, if so, the service data (second service data) of the service end except the first service data are acquired from the service end directly based on the specified identifier, so that the second service data and the local first service data are used as the acquired service data of the service end.

Referring to fig. 5, a data acquisition method provided in an embodiment of the present application is applied to a client, and the method includes:

s210: and acquiring a specified identifier from wireless data corresponding to a server, wherein the specified identifier is used for identifying first service data in the server, and the first service data is fixed service data.

S220: and if the first service data acquired from the server based on the specified identifier in advance is stored locally, determining a service data query range based on the specified identifier, wherein the service data query range is a range corresponding to the second service data.

As can be seen from the foregoing description of the embodiments, in the embodiments of the present application, the specific identifier may have various implementations. The corresponding determined data query ranges may also be different for the specified identifications of the different embodiments.

As a way, the specified identifier is a last identifier sequenced in a specified identifier section, a start identifier of the specified identifier section is a first identifier sequenced in the server, and the specified identifier section is a section where the identifier corresponding to the first service data is located; the determining a service data query range based on the specified identification includes: and taking the range of the identifiers sequenced after the specified identifier as the service data query range. That is, in the case where the first service data is counted from the first identifier, the last identifier is assigned among identifiers corresponding to the service data included in the first service data. And when the identifiers corresponding to the service data are all ordered 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, referring back to FIG. 4, if the designation is 0x0006 in this manner, the determined service data query range is 0x0007 to the last designation.

Alternatively, the specified identifier may include a start identifier and an end identifier, and then the client may use the range from the first identifier in the server to the start identifier, and the range after the end identifier as the service data query range. For example, referring back to FIG. 4, if the start indicator is 0x0004 and the stop indicator is 0x0006 in this manner, the determined service data query range would include a range from 0x0001 (the first indicator of rank) to 0x0003 and after 0x 0007.

S230: triggering the service end to search the service data based on the service data query range so as to acquire the searched second service data.

S240: and taking the second service data and the local first service data as the acquired service data of the service end.

According to the data acquisition method, under the condition that the service end divides the service data into the first service data and the second service data, the client can acquire the first service data from the service end in advance to be stored locally, then in the process of acquiring the service data corresponding to the service end every time later, the client can acquire the second service data only through the appointed identification in the wireless data corresponding to the service end, and further the data quantity of data acquisition from the service end in the process of acquiring the service data every time is reduced, and the efficiency of acquiring the service data from the service end is improved. In addition, in this embodiment, the client may further determine the service data query range according to the specified identifier, so that the server may directly acquire service data based on the service data query range determined by the client, thereby further improving the acquisition efficiency.

Referring to fig. 6, a data acquisition method provided in an embodiment of the present application is applied to a client, and the method includes:

s310: and acquiring a specified identifier from wireless data corresponding to a server, wherein the specified identifier is used for identifying first service data in the server, and the first service data is fixed service data.

S320: and acquiring the equipment identifier of the equipment where the server is located from the wireless data.

Wherein the device identification is information for identifying the uniqueness of the device. In the embodiments of the present application, the device identifier may have various embodiments.

As one approach, device identification may be implemented by a network address to which the device corresponds. In this manner, the network address of the device may be used as the device identification of the device. For example, if the device at the server side sends wireless data by means of bluetooth communication. The wireless data sent based on the bluetooth communication mode carries the bluetooth address of the device, and the client can use the bluetooth address carried in the wireless data as the device identifier of the device. Where a bluetooth address is used as the device identification, the bluetooth address is a public type address so that the bluetooth address of the device is fixed.

Alternatively, the device identification may be a random number generated based on a specified protocol, and the random number generated each time may be different, so that the device identifications corresponding to different devices may be unique. The random number serving as the device identifier may be added to the transmitted wireless data each time the server transmits the wireless data, so that the client receiving the wireless data may know which server the current wireless data is transmitted from.

In the case that the device identifier may have various embodiments, the client may acquire the device identifier in a given manner.

Optionally, if the predetermined manner configured by the client is to obtain the network address carried in the wireless data as the device identifier, the client may directly extract the network address from the wireless data after obtaining the wireless data sent by the server, so as to be used as the device identifier of the device where the server is located. Optionally, if the predetermined manner configured by the client is to obtain the random number carried in the wireless data as the device identifier, the client may directly extract the random number from the wireless data after obtaining the wireless data sent by the server, so as to be used as the device identifier of the device where the server is located.

Furthermore, the client may also perform device identification acquisition in an adaptive manner. It should be noted that, when different service ends identify their own devices, the adopted identification modes may be different. For example, although the wireless data sent by the device may carry a network address, a random network address (random type network address) is adopted by some devices, so that the network addresses of different devices may be the same, and in this case, the network address has no good way to uniquely identify the devices.

As a way, the client may detect the type of the network address adopted in the wireless data during the process of obtaining the device identifier; if the network address is detected to be a fixed type network address, directly taking the acquired network address as the equipment identifier of the equipment for transmitting the wireless data; if the network address is detected to be a random type network address, further detecting whether the wireless data carries a random number generated based on a specified protocol; and if the random number generated based on the specified protocol is detected, the random number generated based on the specified protocol is used as the equipment identification of the equipment for transmitting the wireless data. If the random number generated based on the specified protocol is not detected, all the service data are directly obtained from the service end and are used as the service data corresponding to the service end.

It should be noted that, in the embodiment of the present application, after the client obtains the first service data from the server, the device identifier may be stored in correspondence with the first service data.

S330: and detecting whether service data corresponding to the equipment identifier is stored locally.

As described above, the client may store the device identifier corresponding to the first service data when storing the first service data. The client detects whether the service data corresponding to the device identifier is stored locally or not, and can be understood as that the client determines whether the service data is based on the first service data acquired from the server locally or not. And, the first service data is service data identified by a specified identification in the wireless data where the device identification is located.

S340: and if the service data corresponding to the equipment identifier is not stored locally, determining that the first service data acquired from the server side based on the specified identifier is not stored locally.

S350: and if the service data corresponding to the equipment identifier is stored locally, determining that the first service data acquired from the server side based on the specified identifier is stored locally.

S360: and if the first service data which is acquired from the service end based on the specified identification in advance is stored locally, acquiring second service data from the service end based on the specified identification, wherein the second service data is the service data except the first service data in the service end.

S370: and taking the second service data and the local first service data as the acquired service data of the service end.

According to the data acquisition method, under the condition that the service end divides the service data into the first service data and the second service data, the client can acquire the first service data from the service end in advance to be stored locally, then in the process of acquiring the service data corresponding to the service end every time later, the client can acquire the second service data only through the appointed identification in the wireless data corresponding to the service end, and further the data quantity of data acquisition from the service end in the process of acquiring the service data every time is reduced, and the efficiency of acquiring the service data from the service end is improved. In addition, 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 are correspondingly stored, so that the first service data stored in the server can be directly determined under the condition that the service data corresponding to the device identifier is determined to be stored.

Referring to fig. 7, a data acquisition method provided in an embodiment of the present application is applied to a client, and the method includes:

s410: and acquiring a specified identifier from wireless data corresponding to a server, wherein the specified identifier is used for identifying first service data in the server, and the first service data is fixed service data.

S420: and comparing whether the specified identifier obtained from the wireless data is consistent with the specified identifier stored locally.

It should be noted that, the service end is identified by a specific identifier to distinguish the first service data from the second service data. The client may store the specified identifier based on which the first service data is acquired and the acquired first service data locally after the first service data is acquired from the server based on the specified identifier in the wireless data. It means that the locally stored first service data and the assigned identification are corresponding. The client can detect whether the specified identifier currently acquired from the wireless data is consistent with the locally stored specified identifier after acquiring the specified identifier from the wireless data transmitted from the server each time, if so, the first service data in the characterization server is still unchanged, and then the client can determine that the first service data acquired from the server based on the specified identifier currently acquired from the wireless data is actually stored locally.

For example, if the identifier currently acquired from the wireless data is identifier 1 and the identifier locally acquired by the client is identifier 1, then the client may determine that the identifier acquired from the wireless data is consistent with the locally stored identifier. If the currently acquired specific identifier from the wireless data is identifier 2 and the locally acquired specific identifier of the client is identifier 2, then the client may determine that the specific identifier acquired from the wireless data is inconsistent with the locally stored specific identifier.

Furthermore, it should be noted that the client may establish connection with multiple servers, and the specified identifiers corresponding to the different servers may be the same. In this way, the client may 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 the different servers. For example, the locally stored designation of the client may be as shown in the following table.

ID	Specifying an identification	Device identification
			1	Sign 1	Apparatus 1
2	Sign 2	Device 2
			3	Sign 3	Device 3

If the current identifier obtained from the wireless data is identifier 2 and the device identifier is device 2, the client may query the locally stored identifier for the identifier 2 and the device identifier is the data of device 2 (i.e. the data corresponding to ID 2), and then the client determines that the identifier obtained from the wireless data is consistent with the locally stored identifier. If the currently acquired specified identifier from the wireless data is identifier 2 and the device identifier is device 1, it is determined that the specified identifier acquired from the wireless data is not consistent with the locally stored specified identifier. In this case, it may be further determined that the service end corresponding to the first service data in the device 1 has actually changed, so that the designated identifier for identifying the first service data also changes, and in the case that it is determined that the service end corresponding to the first service data has actually changed, the service data corresponding to the service end needs to be all retrieved from the service end.

S440: and if the service data are inconsistent, determining that the first service data acquired from the service end based on the specified identification in advance are not stored locally.

S450: and if the service data are consistent, determining that the first service data which are acquired from the server side based on the specified identification in advance are stored locally.

S460: and if the first service data which is acquired from the service end based on the specified identification in advance is stored locally, acquiring second service data from the service end based on the specified identification, wherein the second service data is the service data except the first service data in the service end.

According to the data acquisition method, under the condition that the service end divides the service data into the first service data and the second service data, the client can acquire the first service data from the service end in advance to be stored locally, then in the process of acquiring the service data corresponding to the service end every time later, the client can acquire the second service data only through the appointed identification in the wireless data corresponding to the service end, and further the data quantity of data acquisition from the service end in the process of acquiring the service data every time is reduced, and the efficiency of acquiring the service data from the service end is improved. In addition, in this embodiment, in the process of locally storing the first service data, the specific identifier based on which the first service data is acquired is stored locally, so that in the subsequent process of acquiring the service data corresponding to the service end, whether the first service data is stored locally in advance can be quickly determined by detecting whether the specific identifier acquired from the wireless data is stored locally, which is further beneficial to improving the efficiency of acquiring the service data.

Referring to fig. 8, a data acquisition method provided in an embodiment of the present application is applied to a server, and the method includes:

s510: and transmitting wireless data carrying a specified identifier, wherein the specified identifier is used for identifying first service data in the service end, and the first service data is fixed service data.

As one way, the wireless data is broadcast data, and the sending the wireless data carrying the specified identifier includes: and transmitting the broadcast data carrying the specified identification.

S520: and responding to an acquisition request which is sent by the client and corresponds to the specified identifier, acquiring second service data from the server, wherein the acquisition request is sent after the client determines that the first service data acquired from the server based on the specified identifier in advance is locally stored.

S530: and sending the second service data to the client, so that the client can take the second service data and the local first service data as the acquired service data of the server.

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

It should be noted that, for specific details corresponding to the steps in the present embodiment, reference may be made to the content related to the foregoing embodiment.

According to the data acquisition method provided by the embodiment, the specified identification for identifying the first service data in the server is added to the transmitted wireless data by the server, so that the client can acquire the specified identification through the wireless data transmitted by the server, and in the case that the client stores the first service data acquired based on the specified identification in advance, only the second service data can be acquired from the server in the process of acquiring the service data of the whole server. And further, the data volume required to be obtained from the server in the process of obtaining the service data each time is reduced, and the efficiency of obtaining the service data from the server is improved.

It should be noted that, in this embodiment of the present application, before the client obtains the specified identifier from the wireless data corresponding to the server, the client may first detect whether a trust relationship has been established between the client and the server that transmits the wireless data, and if the trust relationship has been established, may directly perform service acquisition in the server according to a service acquisition manner corresponding to the established trust relationship. If the trust relationship is not established, the subsequent acquisition of the specified identifier from the wireless data corresponding to the server can be executed. If a trust relationship is established between the client and the server, the identity authentication between the client and the server is represented.

The following describes, by way of an example, a flow of an actual scenario according to an embodiment of the present application. As shown in fig. 9, the flow shown in fig. 9 includes:

s610: the GATT client acquires broadcast data sent by the GATT server and acquires a specified identifier from the broadcast data.

S620: and the GATT client establishes connection with the GATT server.

S630: the GATT client detects whether a connection is first established with the server.

The GATT client may detect whether to establish a connection with the server for the first time. For example, the detection may be performed by detecting whether the service data corresponding to the device identifier of the device where the GATT server is located is stored locally in the foregoing embodiment, and if the service data corresponding to the device identifier is stored locally, the connection is determined not to be the first connection, otherwise, if the service data corresponding to the device identifier is not stored locally, the connection is determined to be the first connection. For another example, the detection may be performed by detecting whether or not the specific identifier obtained from the broadcast data is identical to the specific identifier stored locally, and if it is detected that the specific identifier obtained from the broadcast data is identical to the specific identifier stored locally, the connection is determined not to be the first connection, whereas if it is detected that the specific identifier obtained from the broadcast data is identical to the specific identifier stored locally, or if the specific identifier is not stored locally, the connection is determined to be the first connection.

S640: if the connection is the first connection, the GATT client triggers the service search to start from the service data which is ranked at the forefront among all the service data of the service end.

The service data in the service end may be arranged according to a certain order. For example, as shown in fig. 4, the corresponding service data identified as 0x0001 is the service data ranked first among all the service data of the service end. Then, if the GATT client determines that the connection is established for the first time with the GATT server, the GATT client triggers to start searching for services from the service data identified as 0x0001 in the GATT server.

S641: and the GATT client stores the first service data in the searched service data locally.

Under the condition that the GATT client determines that the connection with the GATT server is established for the first time, the GATT client searches all service data in the GATT server once, so that all service data in the GATT server are found. Then for convenience

S650: if not, the GATT client triggers the local reading of the first service data.

S651: the GATT client triggers the service searching from the first service data after the specified identification to obtain the second service data.

In the embodiment shown in fig. 9, the designation flag indicates a flag corresponding to the last service data in the manner of performing fixed data detection from the first service data. It is also understood that the designation identifier is the one of the fixed service data for which the corresponding identifier is the largest. Wherein the ordering of the service data is equivalent to the ordering of the identifications corresponding to the service data. For example, referring to fig. 4, if the fixed service data is determined from 0x0001, the determined fixed service data includes service 1, feature descriptor 1, service 2, feature 2, and feature descriptor 2. Then, in the determined unchanged fixed unchanged service data, the corresponding identifier with the largest identifier is 0x0006, and then the determined specified identifier is 0x0006. After the GATT client determines that a connection is first established with the GATT server, the first service data stored locally includes service 1, feature descriptor 1, service 2, feature 2, and feature descriptor 2. Then after a subsequent connection is not established for the first time, a search for service data is started from 0x 0007.

The processing manner after the first service data and the second service data are obtained can be referred to the content in the foregoing embodiment.
