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.

Fig. 1A is a flowchart illustrating a data transmission method according to an exemplary embodiment, where as shown in fig. 1A, the data transmission method is applied to a bluetooth remote control device, and the bluetooth remote control device is communicatively connected to a controlled device, and the method includes the following steps S101 to S103:

in step S101, when it is detected that the bluetooth remote control device is switched to the voice remote control mode, a first prompt message is sent to the controlled device, so that the controlled device updates the preset parameter according to the first prompt message, and sends the updated preset parameter to the bluetooth remote control device.

The bluetooth remote control device may include, but is not limited to, BLE bluetooth remote control, and may include a voice remote control mode and a key remote control mode.

In this embodiment, when the bluetooth remote control device detects that the bluetooth remote control device switches to the voice remote control mode, the bluetooth remote control device sends a first prompt message to a controlled device, for example, a television, and after receiving the first prompt message, the controlled device may increase a connection event length parameter (connection event length) according to the first prompt message, and update a preset parameter, that is, transmission window offset information, according to the increased connection event length parameter, so that a larger time slot for continuously transmitting voice data may be allocated to the bluetooth remote control device.

The connection event length is a connection parameter defined in the BLE protocol specification, and has two parameters, namely a minimum connection event length (min _ ce _ len) and a maximum connection event length (max _ ce _ len). The meaning of these two parameters is the minimum and maximum number of time slots that the controlled device can allocate to the bluetooth remote control device each time the bluetooth remote control device communicates with the controlled device.

In step S102, updated preset parameters are received.

In this embodiment, the bluetooth remote control device may receive a preset parameter, i.e., transmission window offset information, sent by the controlled device.

In step S103, when the updated preset parameter becomes effective, the voice data is transmitted according to the updated preset parameter.

In this embodiment, when the transmission window offset information is validated, the bluetooth remote control device may transmit voice data according to the transmission window offset information, thereby increasing the transmission rate.

According to the data transmission method embodiment, when the Bluetooth remote control device is detected to be switched to the voice remote control mode, the first prompt message is sent to the controlled device, so that the controlled device updates the preset parameters according to the first prompt message, and when the updated preset parameters take effect, the voice data is transmitted according to the updated preset parameters.

Fig. 1B is a flowchart illustrating another data transmission method according to an exemplary embodiment, and as shown in fig. 1B, after the step S101, the method may further include the following steps:

in step S104, when it is detected that the bluetooth remote control device is switched to the key remote control mode, a second prompt message is sent to the controlled device, so that the controlled device restores the preset parameter to the initial value according to the second prompt message, and sends the restored preset parameter to the bluetooth remote control device.

In this embodiment, when the user switches the bluetooth remote control device from the voice remote control mode to the key remote control mode, the bluetooth remote control device may send a second prompt message to the controlled device, and after receiving the second prompt message, the controlled device may restore min _ ce _ len and max _ ce _ len to the initial values according to the second prompt message, so as to restore the preset parameters, that is, the transmission window offset information, to the initial values, and send the restored preset parameters to the bluetooth remote control device.

In step S105, the restored preset parameters are received.

In step S106, when the restored preset parameters become effective, data is transmitted according to the restored preset parameters.

In this embodiment, when the restored transmission window offset information is validated, data may be transmitted according to the restored transmission window offset information. The transmission window offset information is restored to the initial level, so that the Bluetooth remote control equipment can obtain the required time slot and the time slot resource is not wasted.

According to the embodiment of the data transmission method, when the Bluetooth remote control device is detected to be switched to the key remote control mode, the second prompt message is sent to the controlled device, so that the controlled device recovers the preset parameters according to the second prompt message, and when the recovered preset parameters take effect, the data is transmitted according to the recovered preset parameters.

Fig. 2A is a flowchart illustrating a data transmission method according to an exemplary embodiment, where as shown in fig. 2A, the data transmission method is applied to a controlled device, and the controlled device is communicatively connected to a bluetooth remote control device, and the method includes the following steps:

in step S201, a first prompt message sent by the bluetooth remote control device when switching to the voice remote control mode is received, and the preset parameter is updated according to the first prompt message.

In this embodiment, when the bluetooth remote control device detects that the bluetooth remote control device switches to the voice remote control mode, the bluetooth remote control device sends a first prompt message to the controlled device, for example, a television, and after receiving the first prompt message, the controlled device may increase the connection event length according to the first prompt message, and update the preset parameter, that is, the transmission window offset information according to the increased connection event length, so that a larger time slot for continuously transmitting voice data may be allocated to the bluetooth remote control device.

It should be noted that, the BLE protocol specification includes, in addition to the connection event length, connection parameters such as a connection interval (connection interval), a connection delay (connection latency), and a connection timeout (connection timeout), but in this embodiment, the controlled device only increases the connection event length after receiving the first prompt message, and keeps the three parameters of the connection interval, the connection delay, and the connection timeout unchanged. Keeping the connection interval and connection latency unchanged can effectively reduce the power consumption of the Bluetooth remote control.

For example, in the transmission process of voice data, if the CPU of the controlled device is dead due to some reasons or the communication bus of the controlled device and the bluetooth chip thereof has a problem, the bluetooth chip of the controlled device can also work normally, the buffer memory of the bluetooth chip of the controlled device can be filled with the voice data and cannot be transmitted to the controlled device, the bluetooth remote control cannot transmit the voice data to the bluetooth chip of the controlled device, the bluetooth remote control finds that the data cannot be transmitted, and the voice collection is stopped after a period of time. At this time, the bluetooth remote control only needs the time of interval delay to reply the empty packet to the bluetooth chip of the controlled device (in order to maintain the connection), and the power consumption of the bluetooth remote control is less because the product value of interval delay is larger.

For another example, after the user upgrades the controlled device, for example, the television system, the television is turned on, if there is a new bluetooth remote control firmware (firmware) for the television to be updated, during the updating process, if the user presses the switch (power) key to make the television blank, the updating is continued, if the updating cannot be continued due to an accident, it is assumed that the connection parameter interval is reduced, so that the remote control may be in a power-consuming mode all the time, and if the user does not turn on the television for a long time, the remote control may consume light from the battery. In the present embodiment, the interval delay remains unchanged, so that the above-mentioned remote control battery is prevented from being consumed.

In this embodiment, updating the preset parameter, that is, the transmission window offset information according to the increased connection event length parameter is a preferred way to update the preset parameter, and in practical application, the transmission window offset information may also be updated by adjusting other connection parameters.

In step S202, the updated preset parameters are sent to the bluetooth remote control device, so that the bluetooth remote control device transmits the voice data according to the updated preset parameters when the received updated preset parameters become effective.

The controlled device can send the updated preset parameter to the bluetooth remote control device after updating the preset parameter, namely the transmission window offset information, according to the increased connection event length, and the bluetooth remote control device can transmit the voice data according to the updated preset parameter when the received updated preset parameter takes effect, so that the transmission rate is improved.

According to the embodiment of the data transmission method, the first prompt message sent by the Bluetooth remote control device when the Bluetooth remote control device is switched to the voice remote control mode is received, the preset parameter is updated according to the first prompt message, and the updated preset parameter is sent to the Bluetooth remote control device, so that the controlled device transmits the voice data according to the updated preset parameter.

Fig. 2B is a flowchart illustrating another data transmission method according to an exemplary embodiment, and as shown in fig. 2B, after the step S201, the method may further include the following steps:

in step S203, a second prompt message sent by the bluetooth remote control device when switching to the key remote control mode is received, and the preset parameter is restored to the initial value according to the second prompt message.

In this embodiment, when the user switches the bluetooth remote control device from the voice remote control mode to the key remote control mode, the bluetooth remote control device may send a second prompt message to the controlled device, and after receiving the second prompt message, the controlled device may restore min _ ce _ len and max _ ce _ len to the initial values according to the second prompt message, so as to restore the preset parameters, that is, the transmission window offset information, to the initial values.

In step S204, the recovered preset parameters are sent to the bluetooth remote control device, so that the bluetooth remote control device transmits data according to the recovered preset parameters when the received recovered preset parameters become effective.

In this embodiment, the controlled device may send the recovered transmission window offset information to the bluetooth remote control device, so that the bluetooth remote control device may transmit data according to the recovered transmission window offset information when the recovered transmission window offset information is valid. The transmission window offset information is restored to the initial level, so that the Bluetooth remote control equipment can obtain the required time slot and the time slot resource is not wasted.

According to the embodiment of the data transmission method, the second prompt message sent by the Bluetooth remote control device when the Bluetooth remote control device is switched to the key remote control mode is received, the preset parameter is restored to the initial value according to the second prompt message, and then the restored preset parameter is sent to the Bluetooth remote control device, so that the Bluetooth remote control device can transmit data according to the restored preset parameter.

As shown in fig. 2C, bluetooth remote controls 21 to 23 are all in communication connection with controlled device 24, when a voice key of bluetooth remote control 21 is pressed by a user, bluetooth remote control 21 detects that bluetooth remote control 21 switches to a voice remote control mode, and then sends a first prompt message to controlled device 24, after receiving the first prompt message, controlled device 24 increases min _ ce _ len and max _ ce _ len according to the first prompt message, and updates transmission window offset information according to increased min _ ce _ len and max _ ce _ len, so that a larger time slot for continuously transmitting voice data can be allocated to bluetooth remote control 21, and the rate of transmitting voice data by bluetooth remote control 21 is increased.

Fig. 3 is a flowchart illustrating a data transmission method according to an exemplary embodiment, where the data transmission method is applied to a bluetooth remote control device, and the bluetooth remote control device is communicatively connected to a controlled device, as shown in fig. 3, and the method includes the following steps:

in step S301, when it is detected that the bluetooth remote control device is switched to the voice remote control mode, a first prompt message is sent to the controlled device, so that the controlled device sends a transmission command to the bluetooth remote control device when it is determined that the preset parameter is not changed according to the first prompt message.

In this embodiment, when the bluetooth remote control device detects that the bluetooth remote control device switches to the voice remote control mode, the bluetooth remote control device sends a first prompt message to a controlled device, for example, a television, and after receiving the first prompt message, the controlled device may increase a connection event length parameter according to the first prompt message, and update a preset parameter, that is, transmission window offset information, according to the increased connection event length parameter, and if the preset parameter is not changed, send a transmission command to the bluetooth remote control device.

It should be noted that the embodiment is different from the embodiment shown in fig. 1A in that: the updated default parameters in the embodiment shown in fig. 1A are changed, but not changed in the embodiment. In this embodiment, the reason why the preset parameter is not changed is as follows: enough time for the Bluetooth remote control device to transmit voice data is not allocated to other Bluetooth remote control devices after the current communication time point of the Bluetooth remote control device, so that the communication time with the Bluetooth remote control device can be prolonged and increased.

In step S302, a transmission command is received, and voice data is transmitted according to the transmission command and preset parameters.

In this embodiment, since the preset parameter, that is, the transmission window offset information, is not changed, the bluetooth remote control device receives the transmission command, and transmits the voice data according to the transmission command and the preset parameter. In general, there is a time difference between the bluetooth remote control device transmitting the voice data according to the preset parameters, but in order to transmit the voice data as soon as possible, the embodiment transmits a transmission command to the bluetooth remote control device, so that the bluetooth remote control device can transmit the voice data after receiving the transmission command.

According to the data transmission method embodiment, when the Bluetooth remote control device is detected to be switched to the voice remote control mode, the first prompt message is sent to the controlled device, so that the controlled device sends the transmission command to the Bluetooth remote control device when the preset parameter is determined not to be changed according to the first prompt message, and therefore the Bluetooth remote control device can transmit voice data according to the received transmission command and the preset parameter, and the purpose of transmitting the voice data as soon as possible is achieved.

Fig. 4 is a flowchart illustrating a data transmission method according to an exemplary embodiment, where the data transmission method is applied to a controlled device, and the controlled device is communicatively connected to a bluetooth remote control device, as shown in fig. 4, and the method includes the following steps:

in step S401, a first prompt message sent by the bluetooth remote control device when switching to the voice remote control mode is received.

In this embodiment, when the bluetooth remote control device detects that it switches to the voice remote control mode, a first prompt message may be sent to a controlled device, such as a television.

In step S402, if it is determined that the preset parameter has not changed according to the first prompt message, a transmission command is sent to the bluetooth remote control device, so that the bluetooth remote control device transmits voice data according to the received transmission command and the preset parameter.

After receiving the first prompt message, the controlled device may increase the connection event length parameter according to the first prompt message, update the preset parameter, that is, the transmission window offset information, according to the increased connection event length parameter, and send a transmission command to the bluetooth remote control device if the preset parameter is not changed.

Wherein the connection event length parameter includes a minimum connection event length and a maximum connection event length.

According to the embodiment of the data transmission method, the transmission command is sent to the Bluetooth remote control equipment, so that the Bluetooth remote control equipment can transmit the voice data according to the received transmission command and the preset parameters, and the purpose of transmitting the voice data as soon as possible is achieved.
