As shown in fig. 1, the present invention provides a recording method based on a bluetooth wireless answering device, which includes:
s101, establishing Bluetooth connection between a mobile terminal and Bluetooth wireless answering equipment;
here, the mobile terminal includes a smart phone, a tablet personal computer with a call function, etc., a bluetooth module is generally built in these devices, and can be wirelessly connected with a bluetooth device, and the bluetooth wireless answering device includes a bluetooth headset and other devices with an audio playing function and a microphone, and since the bluetooth connection between the mobile terminal and the bluetooth wireless answering device is common in the prior art, it is not described in detail here.
S102, judging the working mode of the Bluetooth wireless answering equipment;
here, the operation mode of the bluetooth wireless listening device generally includes an SCO mode and an A2DP mode, the SCO mode is used to establish an SCO link connection with the mobile terminal when the bluetooth wireless listening device is in a call, and the A2DP mode is used to establish an ACL link connection with the mobile terminal when the bluetooth wireless listening device is listening to high-quality audio information.
The method for judging the working mode of the Bluetooth wireless answering device comprises the following steps:
monitoring an interface called by the mobile terminal when the mobile terminal is connected with the Bluetooth wireless answering device in a Bluetooth mode, and if the interface called by the mobile terminal is a PCM interface, judging that the working mode of the Bluetooth wireless answering device is an SCO mode; and if the interface called by the mobile terminal is a UART interface, judging that the working mode of the Bluetooth wireless answering equipment is an A2DP mode.
The monitoring of the interface called by the mobile terminal can be realized by monitoring whether the level of the interface changes, when a certain interface called by the mobile terminal transmits data, the interface transmits data packets through the change of the level, and when the certain interface called by the mobile terminal does not exist, the level of the interface does not change. Therefore, the Bluetooth wireless answering device can know whether the Bluetooth wireless answering device is in a conversation or listening to music or reading only by monitoring the level changes of the PCM interface and the UART interface at the same time.
S103, when the working mode of the Bluetooth wireless answering device is an SCO mode, calculating the distance between the mobile terminal connected with the Bluetooth and the Bluetooth wireless answering device according to a ranging positioning algorithm;
when the working mode of the Bluetooth wireless answering device is the SCO mode, the Bluetooth wireless answering device is actually in a conversation;
in some existing technologies, a mobile terminal is often used to establish a bluetooth connection with a bluetooth wireless answering device, that is, a policy of changing a working mode of the bluetooth wireless answering device to an SCO mode and recording is performed, however, this policy does not consider whether a user is making a call or not, and if the user wants to listen to music, the SCO mode greatly reduces the sound quality of the music and reduces the user experience. In addition, a user generally does not know whether important sensitive information is involved in the call process before making and receiving calls, and the existing Bluetooth recording strategy records whether the call content contains the important sensitive information, so that the memory of the mobile terminal is occupied, the user needs to manually clear and delete the call content, and the use experience of the user is reduced.
The ranging and positioning algorithm can adopt a tof ranging and positioning algorithm or an rssi ranging and positioning algorithm, and certainly, in order to obtain better positioning accuracy, an improved ranging and positioning algorithm based on the tof ranging and positioning algorithm or the rssi ranging and positioning algorithm can be adopted.
S104, comparing the distance between the mobile terminal and the Bluetooth wireless answering device with a preset distance threshold value;
when the distance between the mobile terminal and the Bluetooth wireless answering device is larger than or equal to a preset distance threshold value, receiving a recording instruction signal sent by the Bluetooth wireless answering device, wherein the recording instruction signal is sent by the Bluetooth wireless answering device when a user touches the Bluetooth wireless answering device according to a preset rule, and controlling the mobile terminal to acquire and store call voice data received and sent by the Bluetooth wireless answering device according to the recording instruction signal; when the distance between the mobile terminal and the Bluetooth wireless answering device is smaller than a preset distance threshold value, a call recording method of the mobile terminal is not changed;
the preset distance threshold value is generally 3m, the farthest distance that the bluetooth wireless answering device can be used from the mobile terminal is generally 10m in the bluetooth connection state, however, the bluetooth wireless answering device is used for separating from the constraint of a wire harness, so that a user can do other work outside 3m, and listening to audio information once is common, for example, the user can listen to music while cooking in a kitchen when wearing a bluetooth headset, and the mobile phone is placed in a living room so as not to be contaminated by oil smoke and water drops in the kitchen.
The bluetooth wireless answering device can be provided with a touch panel, after a user contacts the touch panel and moves according to a preset path, the bluetooth wireless answering device sends the recording instruction signal, for example, the touch panel is arranged on the outer wall of an earmuff of the head-wearing bluetooth headset, the preset path on the touch panel is a horizontal transverse line, the user touches one end of the transverse line on the touch panel with a finger and slides to the other end of the transverse line to trigger the recording instruction signal of the bluetooth wireless answering device, and small bulges can be arranged at two ends of the horizontal transverse line on the touch panel for the convenience of the user, so as to help the user to touch and identify the path, and the preset path can be in other modes such as a circle or a triangle; or after the user knocks the touch panel for the preset times, the Bluetooth wireless answering device sends the recording instruction signal, and the preset times can be set to be 3 times or 4 times and the like.
The Bluetooth wireless answering device can be further provided with an entity key, and after a user presses the entity key for a preset number of times, the Bluetooth wireless answering device sends the recording instruction signal, and the preset number of times can be set for 3 times or 4 times and the like, such as the existing in-ear Bluetooth earphone.
The method for calling and recording the mobile terminal is a method for triggering the calling and recording function only by pressing a preset key and waking up the mobile terminal.
And S105, when the working mode of the Bluetooth wireless answering device is an A2DP mode, the call recording method of the mobile terminal is not changed.
Here, when the operating mode of the bluetooth wireless listening device is the A2DP mode, it actually means that the bluetooth wireless listening device is listening to music or reading.
The method for calling and recording the mobile terminal is a method for triggering the calling and recording function only by pressing a preset key and waking up the mobile terminal.
In the using process of the embodiment, whether the state of the Bluetooth wireless answering device is listening to music or calling can be known by judging the working mode of the Bluetooth wireless answering device, and then whether the triggering strategy of the call recording function needs to be changed or not is judged by measuring and calculating the calling state, and when the distance between the Bluetooth wireless answering device and the mobile terminal is too large, the strategy that a user can trigger the recording instruction signal through the Bluetooth wireless answering device is started, so that the user can still quickly start the call recording function of the mobile terminal after wearing the Bluetooth wireless answering device and when having a certain distance from the mobile terminal, and important information in the call process is avoided being omitted by the user.
