In order to save power, the bluetooth connection device switches the connection parameter to a connection parameter with low power consumption when data transmission is not required, and switches the connection parameter to a connection parameter with high power consumption when data transmission is required. However, a certain time is required for switching the connection parameters, which may result in that when a large amount of data needs to be transmitted, the connection parameters cannot be updated in time, so that a large amount of data cannot be transmitted in time, and the data transmission speed is affected. Therefore, how to simultaneously save power and increase data transmission speed is an urgent technical problem to be solved.

The technical scheme provided by the embodiment of the disclosure can have the following beneficial effects:
when the embodiment of the disclosure is applied to the Bluetooth slave device, in response to detecting that the Bluetooth slave device is in a first data transmission state, configuring the connection parameter of the Bluetooth slave device as a first connection parameter; sending indication information to a Bluetooth master device connected with a Bluetooth slave device, wherein the indication information is used for indicating the Bluetooth master device to configure the connection parameter as the first connection parameter; and responding to the received Bluetooth data transmission instruction, and performing data transmission with the Bluetooth master device based on the first connection parameters.

Therefore, the embodiment of the disclosure can take into account both the power saving and the data transmission efficiency of the bluetooth slave device.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure.

Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
For convenience of understanding, the embodiment of the disclosure is applied to a scenario that the bluetooth slave device is in communication connection with the bluetooth master device in a bluetooth connection manner. The bluetooth slave device may send its data to the bluetooth master device in a bluetooth connection manner, for example, the bluetooth slave device may send voice information or key information to the bluetooth master device, so that the bluetooth master device performs a response operation based on the voice information or the key information. In practical applications, the bluetooth slave device may include: bluetooth remote controller, and smart mobile phone, panel computer etc. this bluetooth master device can include: bluetooth master devices such as intelligent televisions, intelligent bedside lamps and intelligent refrigerators. Of course, in other embodiments, the bluetooth master device may also be a smart phone, a tablet computer, a notebook computer, or a desktop computer. The present disclosure is not limited in this regard.
Fig. 1 is a flow chart illustrating a data transmission method according to an exemplary embodiment, which is applied to a bluetooth remote control device, as shown in fig. 1, and includes the following steps:
step 11: in response to detecting that the Bluetooth slave device is in a first data transmission state, configuring connection parameters of the Bluetooth slave device as first connection parameters; sending indication information to a Bluetooth master device connected with the Bluetooth slave device, wherein the indication information is used for indicating the Bluetooth master device to configure the connection parameter as the first connection parameter;
step 12: and responding to the received Bluetooth data transmission instruction, and performing data transmission with the Bluetooth master device based on the first connection parameters.
It should be noted that, after the bluetooth slave device and the bluetooth master device establish a connection, all data communication is performed in a connection event. And the connection event and the sleep time occur alternately. In practice, most of the time between the bluetooth slave and the bluetooth master is in sleep time, in which case the power consumption is relatively low, while in connection events the power consumption is relatively high. This is one of the reasons for power saving in bluetooth communication.
Based on this, the connection parameters of bluetooth include, but are not limited to, the following three parameters:
connection Interval (Connection Interval), a frequency hopping mechanism is used in Connection of two devices connected for bluetooth communication. Two devices transmit and receive data using a particular channel and then use the new channel after a period of time. The two devices send and receive data at the switch signal as a connection event. Although no application data is sent and received, the two devices still exchange link layer data, i.e., send null packets to maintain the connection. Here, the connection interval refers to a time interval from the start of one connection event to the start of the next connection event.
Device Latency or device Latency (Latency), which allows the bluetooth master and/or the bluetooth slave to skip a certain number of connection events without data to be sent, in which connection events there is no need to reply, i.e. reply to the other party's data packet, which can save more power. For example, if Latency is 0, a packet, including an empty packet or a data packet, needs to be replied to every connection interval of communication, and if Latency is 5, a packet needs to be replied to every connection interval of six communication, so that the connection between the bluetooth slave device and the bluetooth master device can be maintained.
A Timeout or Supervision Timeout (Supervision Timeout) parameter that sets a Timeout that will automatically disconnect if no communication occurs in the bluetooth device during this time.
It can be appreciated that the Connection Interval is shortened, the bluetooth slave device communicates with the bluetooth master device more frequently, the data throughput speed is increased, the data transmission time is shortened, and the power consumption of the device can be increased. The connection Interval increases, the communication frequency decreases, the data throughput speed decreases, the data transmission time increases, and the device can reduce power consumption. Latency is reduced or set to 0, packets of the bluetooth slave device need to be replied in each connection event, power consumption is increased, and data transmission speed is increased. Latency is lengthened, power consumption is reduced, and data transmission speed is reduced.
In order to save power consumption of the bluetooth device, for example, Connection Interval is shortened or Latency is reduced when data transmission is required, and for example, Connection Interval is increased or Latency is lengthened when data transmission is not required. In the related art, during the switching process of the connection parameters, two parties needing bluetooth connection may perform real-time negotiation interaction for the connection parameters, for example, the bluetooth slave device needs to send an update request of the connection parameters to the bluetooth master device first, the bluetooth master device indicates new connection parameters and effective time thereof to the bluetooth slave device after making a decision based on the update request, the effective time to be generated arrives, and the bluetooth slave device and the bluetooth master device can communicate based on the new bluetooth connection parameters, so obviously, the problem that the connection parameters are not switched in time, which causes unnecessary power waste or low efficiency of data transmission, and the like may be obviously caused.
The first data transmission state here corresponds to the first connection parameter. The first data transmission state may be a data transmission state when data transmission is required. It can be understood that, if the first data transmission state is a data transmission state when data transmission is required, the first Connection parameter herein corresponds to a Connection parameter with higher power consumption, for example, Latency in the first Connection parameter is set to a smaller value, or Connection Interval is set to a shorter time Interval, so that data transmission in the current first data transmission state can be facilitated. For example, the first data transmission state may be a data transmission state when the data transmission speed is greater than the transmission speed threshold; for example, the first data transmission state may be a data transmission state in which the data transmission amount is greater than the transmission amount threshold.
In the embodiment of the disclosure, in response to detecting that the bluetooth slave device is in the first data transmission state, the connection parameter of the bluetooth slave device is directly configured as the first connection parameter, and the indication information for indicating that the connection parameter configured by the bluetooth master device is the first connection parameter is directly sent to the bluetooth master device connected to the bluetooth slave device, so that processes such as negotiation interaction and the like between the bluetooth slave device and the bluetooth master device during connection parameter switching can be omitted, so that the bluetooth slave device and the bluetooth master device can communicate by using the first connection parameter as soon as possible, that is, the bluetooth slave device is switched to the connection parameter with higher power consumption from the low-power-consumption connection parameter without data transmission as soon as possible, so that the bluetooth slave device can perform data transmission based on the connection parameter with higher transmission speed, and thus the efficiency of data transmission is ensured. Meanwhile, the embodiment of the disclosure can switch from the low-power-consumption connection parameters which do not need data transmission to the connection parameters with high power consumption as soon as possible, so that the low-power-consumption connection parameters can still be used for saving power for the parameters of the bluetooth slave device when the data transmission is not needed. Therefore, in the embodiment of the disclosure, at least the bluetooth slave device can have both power saving and data transmission efficiency.
In some embodiments, the method further comprises:
sending data transmission request information to the Bluetooth master device;
receiving request result information replied by the Bluetooth master device based on the data transmission request information;
and generating the Bluetooth data transmission instruction in response to the request result information indicating that the request is allowed.
Here, before data transmission with the bluetooth master device, data transmission request information is sent to the bluetooth master device in advance to request the bluetooth master device to perform data transmission. In this embodiment, because the connection parameters of the bluetooth master device and the bluetooth slave device are configured as the first connection parameters, during the process of replying the permission request communication to the bluetooth slave device, the bluetooth master device and the bluetooth master device can quickly enter a transmission state suitable for the first data transmission state due to the adopted first connection parameters, for example, the bluetooth slave device can be replied by using a lower Latency parameter, so that the bluetooth slave device can quickly enter a transmission state with higher data transmission efficiency, and thus, the bluetooth slave device can further take into account both power saving and data transmission efficiency.
In some embodiments, the step 11 is to configure the connection parameter of the bluetooth slave device as the first connection parameter in response to detecting that the bluetooth slave device is in the first data transmission state; sending indication information to a Bluetooth master device connected with the Bluetooth slave device, including:
updating connection parameters of the Bluetooth slave device from second connection parameters to the first connection parameters in response to detecting that the Bluetooth slave device changes from a second data transmission state to the first data transmission state; sending first indication information to a Bluetooth master device connected with the Bluetooth slave device, wherein the first indication information is used for indicating the Bluetooth slave device to update a third connection parameter to the first connection parameter; the second connection parameter is the connection parameter adopted by the bluetooth slave device in the second data transmission state, the data transmission speed in the first data transmission state is greater than the data transmission speed in the second data transmission state, the power consumption of the bluetooth slave device in the first connection parameter is greater than the power consumption in the second connection parameter, and the third connection parameter is the connection parameter adopted by the bluetooth master device before receiving the first indication information.
Here, the second data transmission state is a different data transmission state from the first data transmission state. It will be appreciated that the second data transfer state may be a data transfer state having a lower transmission speed requirement than the first data transfer state. Illustratively, if the data transfer rate corresponding to the first data transfer state is greater than the transfer rate threshold, the data transfer rate corresponding to the second data transfer state is less than or equal to the transfer rate threshold. Illustratively, if the data transfer amount corresponding to the first data transfer state is greater than the transfer amount threshold, the data transfer rate corresponding to the second data transfer state is less than or equal to the transfer rate threshold.
The third connection parameter is the connection parameter collected by the bluetooth master device before receiving the first indication information. In some embodiments, the third connection parameter may be the same as the second connection parameter. Namely, the connection parameters used by the bluetooth master device in the second data transmission state with the bluetooth slave device before receiving the first indication information. In other embodiments, the third connection parameter may be different from the second connection parameter, that is, a default connection parameter used by the bluetooth master device or a connection parameter used by the bluetooth master device and another bluetooth device before the bluetooth master device receives the first indication information.
In this embodiment, by detecting that the bluetooth slave device changes from the second data transmission state to the first data transmission state as the timing for configuring the first connection parameter, the connection parameter can be updated quickly at the timing for updating the data transmission state of the bluetooth slave device, thereby facilitating the efficiency of data transmission.
In some embodiments, referring to fig. 2, fig. 2 is another flow chart illustrating a data transmission method according to an exemplary embodiment, as shown in fig. 2, the method further includes:
step 21: receiving a configuration result based on the first connection parameter returned by the Bluetooth master device;
step 12, that is, the data transmission with the bluetooth master device based on the first connection parameter includes:
step 121: and responding to the configuration result indicating that the configuration is successful, and performing data transmission with the Bluetooth master device based on the first connection parameters.
It can be understood that, after receiving the indication information, the bluetooth master configures the first connection parameter for itself based on the indication of the indication information, but due to the connection status of the bluetooth master, the communication status of the bluetooth master, or the performance of the bluetooth master, the configuration may be unsuccessful. In this embodiment, the success rate of data transmission between the two bluetooth devices can be determined by receiving the configuration result that the bluetooth master device determines that the configuration is successful and then performing data transmission with the bluetooth master device based on the first connection parameter.
In some embodiments, the method further comprises:
determining the transmission speed of the current data of the Bluetooth slave device;
determining that the Bluetooth slave device is in the first data transmission state in response to the current data transmission speed being greater than a transmission speed threshold.
For example, the determining the transmission speed of the current data of the bluetooth slave device may include:
and determining the transmission speed of the current data of the Bluetooth slave equipment according to the preset time periodicity.
It is understood that the preset time period may be a preset fixed preset time period. In some embodiments, the preset time period may be set to be short so as to be able to determine the transmission speed of the current data of the bluetooth slave device in time, for example, may be set to 1 second; of course, in other embodiments, to save power, the preset time period may be set longer to save power for the bluetooth slave device, for example, 10 seconds.
In other embodiments, the predetermined time period may also be dynamically variable. For example, the preset time period may be determined from historical usage information of the device by bluetooth. For example, a bluetooth slave device, such as a bluetooth remote controller, is usually used between 7 pm and 9 pm, and the preset time period of the time period may be set to be shorter, so as to timely increase the detected transmission speed of the current data to determine whether the bluetooth slave device is in the first data transmission state, and thus timely update the connection parameter to the first connection parameter in the first data transmission state, so as to improve the efficiency of data transmission of the bluetooth slave device. For another example, at times other than 7 pm to 9 pm, the preset time period for this period may be set longer, typically to save power for the bluetooth slave device.
According to the embodiment of the disclosure, under the condition that it is detected that the current data transmission speed is greater than the transmission speed threshold, it can be determined that the bluetooth slave device is in the first data transmission state, so that a favorable guarantee can be provided for updating the connection parameters of the bluetooth slave device and the bluetooth master device to the first connection parameters based on the first data transmission state subsequently, so as to ensure the validity of data transmission between two bluetooth devices.
It should be noted that, in the embodiment of the present disclosure, taking the connection parameter as Latency as an example, when the bluetooth slave device is in the first data transmission state, the connection parameter of the bluetooth slave device will be automatically configured to have Latency of 1, that is, the bluetooth master device replies 1 packet at an interval between two communication connection events. However, in order to be able to adapt to a plurality of different data transmission speeds, the first connection parameters may actually also be dynamically configured.
In some embodiments, the method further comprises:
determining a data transmission level of the current data transmission speed in response to the current data transmission speed being greater than a transmission speed threshold;
and determining a fourth connection parameter corresponding to the data transmission grade as the first connection parameter according to the data transmission grade.
It is understood that the larger the current data transmission speed is, the higher the corresponding data transmission level is, and the smaller the corresponding first connection parameter, for example, Latency is.
Illustratively, the data transmission level is divided into three levels, where a data transmission level 1 is configured with Latency of 2, a data transmission level 2 is configured with Latency of 1, and a data transmission level 3 is configured with Latency of 0.
In the embodiment of the disclosure, the data transmission grades of different grades are divided according to different data transmission speeds in the first data transmission state, so that the connection parameters suitable for the current data transmission speed are configured more finely, and thus, the data transmission efficiency of the bluetooth slave device can be further improved.
In other embodiments, the method further comprises:
determining the data transmission quantity indicated by the Bluetooth data transmission instruction;
determining that the Bluetooth slave device is in the first data transmission state in response to the data transmission amount being greater than a transmission amount threshold.
It can be understood that the corresponding data transmission amount is different under different data transmission scenes. And the data transmission scenes indicated by different data transmission instruction instructions are different. For example, if the multimedia file is transmitted between the tablet and the tablet, the data transmission quantity is obviously larger than that of the remote control instruction transmitted between the Bluetooth remote controller and the television.
According to the embodiment of the disclosure, under the condition that the current data transmission amount is detected to be larger than the transmission amount threshold, the bluetooth slave device can be determined to be in the first data transmission state, so that the connection parameters of the bluetooth slave device and the bluetooth master device can be updated to the first connection parameters based on the first data transmission state subsequently, and a favorable guarantee is provided for ensuring the validity of data transmission between two bluetooth devices.
It should be noted that, in the embodiment of the present disclosure, taking the connection parameter as Latency as an example, when the bluetooth slave device is in the first data transmission state, the connection parameter of the bluetooth slave device will be automatically configured to have Latency of 1, that is, the bluetooth master device replies 1 packet at an interval between two communication connection events. However, in order to be able to adapt to a plurality of different data transmission speeds, the first connection parameters may actually also be dynamically configured.
In other embodiments, the method further comprises:
determining a transmission capacity level of the current data transmission capacity in response to the data transmission capacity being greater than a transmission capacity threshold;
and determining a fifth connection parameter corresponding to the data transmission quantity grade as the first connection parameter according to the transmission quantity grade.
It is understood that the larger the data transmission amount, the higher the corresponding transmission amount level, and the smaller the corresponding first connection parameter, for example, Latency.
Illustratively, the transmission capacity level is divided into three levels, where the transmission capacity level 1 is allocated with Latency of 2, the transmission capacity level 2 is allocated with Latency of 1, and the transmission capacity level 3 is allocated with Latency of 0.
In the embodiment of the disclosure, the transmission quantity grades of different grades are divided according to different transmission quantities in the first data transmission state, so that the connection parameters suitable for the current data transmission quantity are configured more finely, and thus, the data transmission efficiency of the bluetooth slave device can be further improved.
The embodiment of the present invention further discloses a data transmission method, and the following data transmission method is applied to the bluetooth master device, which is similar to the data transmission method applied to the bluetooth slave device, and for technical details which are not disclosed in the data transmission method embodiment executed by the bluetooth master device, please refer to the description of the data transmission method example executed by the bluetooth slave device, and a detailed description is not provided herein.
Fig. 3 is a flowchart illustrating a data transmission method according to another exemplary embodiment, which is applied to a bluetooth master device, as shown in fig. 3, and includes the following steps:
step 31: receiving indication information sent by the Bluetooth slave device, wherein the indication information is used for indicating that the Bluetooth master device configures connection parameters as first connection parameters, and the first indication information is sent by the Bluetooth slave device in a first data transmission state;
step 32: and carrying out data transmission with the Bluetooth slave equipment based on the first connection parameter.
When the embodiment of the disclosure is applied to the bluetooth master device, the indication information sent by the bluetooth slave device is received, and the configured first connection parameter is indicated to perform data transmission with the bluetooth slave device based on the indication information. In the embodiment of the disclosure, negotiation interaction such as a change request for the connection parameter between the bluetooth slave device and the bluetooth master device is not required, so that timely change of the connection parameter when the bluetooth slave device needs to perform data transmission in the first data transmission state can be reduced, and the efficiency of data transmission is facilitated. Meanwhile, before the bluetooth master device does not receive the indication information, that is, when the bluetooth slave device is not in the first data transmission state, the connection parameter may not be configured as the first connection parameter adapted to the first data transmission state, so that the power of the bluetooth master device can be reduced. Therefore, the embodiment of the disclosure can also take into account the power saving and data transmission efficiency of the bluetooth master device.
In some embodiments, the method further comprises:
receiving data transmission request information sent by Bluetooth master equipment;
replying request result information to the Bluetooth slave equipment based on the data transmission request information, wherein the request result information is used for generating the Bluetooth data transmission instruction for the Bluetooth slave equipment based on the request result information indicating permission request.
In this embodiment, because the connection parameters of the bluetooth master device and the bluetooth slave device are configured as the first connection parameters, during the process of replying the permission request communication to the bluetooth slave device, the bluetooth master device and the bluetooth master device can quickly enter a transmission state suitable for the first data transmission state due to the adopted first connection parameters, for example, the bluetooth slave device can be replied by using a lower Latency parameter, so that the bluetooth slave device can quickly enter a transmission state with higher data transmission efficiency, and thus, the bluetooth slave device can further take into account both power saving and data transmission efficiency.
In some embodiments, referring to fig. 4, fig. 4 is a further flowchart illustrating a data transmission method according to another exemplary embodiment, as shown in fig. 4, the method further comprising:
step 41: configuring the first connection parameter for the Bluetooth master device based on the indication information to generate a configuration result;
step 42: returning the configuration result to the Bluetooth slave device;
step 32: namely, the data transmission with the bluetooth slave device based on the first connection parameter includes:
and in response to the configuration result indicating that the configuration is successful, performing data transmission with the Bluetooth slave device based on the first connection parameter.
In this embodiment, the success rate of data transmission between the two bluetooth devices can be determined by receiving the configuration result that the bluetooth master device determines that the configuration is successful and then performing data transmission with the bluetooth master device based on the first connection parameter.
Further, the embodiments of the present disclosure provide a specific embodiment to further understand the data transmission method provided by the embodiments of the present disclosure.
It should be noted that, a bluetooth device, such as a bluetooth remote controller, a bluetooth watch, or a bluetooth bracelet, uses a bluetooth chip, and in general, in order to save power, the bluetooth device requests a host device connected to the bluetooth device to update connection parameters, so that the bluetooth device needs to communicate with a host, such as a television or a mobile phone. That is, the bluetooth device can maintain connection with the host by using non-aggressive connection parameters, and when communication with the host is needed, the bluetooth device can request the host to update the aggressive connection parameters, so that the device can quickly interact with the host. It is understood that the bluetooth device is the bluetooth slave device in the above embodiments, and the host device is the bluetooth master device in the above embodiments.
In the related art, a certain process is required for switching connection parameters between the bluetooth device and the host device, the effective time for switching the bluetooth chip of the host device may be required, and interaction such as a request for changing the connection parameters between the bluetooth device and the host device is also required. These factors will inevitably cause the connection parameters to be changed in time, thereby affecting the data transmission speed of the bluetooth device.
Illustratively, one of the connection parameters is called Latency, which is intended to control the frequency with which a bluetooth device sends packets back to the host device in order to maintain a connection. If Latency is 0, the Bluetooth device needs to return a packet to the host device every 1 connection event, and if Latency is 5, the Bluetooth device needs to return a packet to the host device every 6 connection events. Therefore, when the bluetooth device wants to save power, it needs to request the host to change the connection parameters, and increase Latency, and when the bluetooth wants to transmit a large amount of data, it requests the host to decrease Latency, but this request interaction and so on all need a certain time, resulting in the Latency being not updated in time.
In the embodiment of the disclosure, the two devices may negotiate the first connection parameter in advance, and when the bluetooth device needs to perform data transmission, the connection parameter is automatically changed into the first connection parameter, and the host device is instructed to also change the first connection parameter, so that the two devices can perform data transmission in time based on the first connection parameter.
The embodiment of the disclosure can save power for the equipment and update the connection parameters in time during high-capacity data transmission so as to ensure the data transmission speed.
