Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of an information broadcasting method based on bluetooth connection according to an embodiment of the present invention, where the embodiment is applicable to a situation where a user terminal is connected to a vehicle through bluetooth, but induced information cannot be broadcasted due to a vehicle failure, and the method may be executed by a corresponding information broadcasting device based on bluetooth connection, where the device may be implemented in a software and/or hardware manner and may be configured on the user terminal.
As shown in fig. 1, the information broadcasting method based on bluetooth connection provided in the embodiment of the present invention may include:
and S101, responding to the soundless broadcast of the vehicle-mounted terminal, and switching the Bluetooth link to the synchronous link.
The bluetooth link is mainly used for transmitting data communication with high requirement on time, the bluetooth link types include two types, namely Synchronous link (SCO) and Asynchronous link (ACL), the Synchronous link is mainly used for Synchronous voice transmission, and the ACL link is mainly used for packet data transmission.
Specifically, the connections of the synchronous link are symmetrical connections, and the reserved time slots are used for transmitting data packets. After the connection is established, the master device and the slave device may send the synchronization link data packet without being selected. The synchronization link data packet may carry either voice or data, but is used to retransmit only the corrupted portion of the data as it is being transmitted.
Asynchronous links are directed packets that support both symmetric and asymmetric connections (either one-to-one or one-to-many). The master is responsible for controlling the link bandwidth and deciding how much bandwidth each slave in the piconet can occupy and the symmetry of the connection. The slave device can only transfer data if it is selected. The asynchronous link also supports the reception of broadcast messages from the master device to all slave devices in the piconet.
The use of bluetooth for playing inducement information (e.g. music or navigation voice) is based on the A2DP (Advanced Audio Distribution Profile) protocol, where the A2DP protocol is a high quality Audio protocol running on an asynchronous link that defines the protocol and procedures for transmitting high quality Audio information, such as mono or stereo, over the asynchronous link. Therefore, the guidance information played by the vehicle-mounted terminal is transmitted to the vehicle-mounted terminal by the user terminal through the asynchronous link. And when the A2DP protocol has problems, the vehicle terminal is caused to play the silence. Therefore, for this situation, the user can manually trigger the bluetooth device broadcast control on the user terminal, and then the user terminal switches the bluetooth link connecting the vehicle-mounted terminal to the synchronous link in response to the bluetooth connection setting request when the vehicle-mounted terminal is broadcasted to be silent.
Further, since the synchronous link is mainly used for answering a call, in order to avoid that normal conversation is affected due to abnormal sound channels caused by link switching, when the bluetooth link connected with the vehicle-mounted terminal is switched to the synchronous link, whether the user terminal is in conversation is judged at first. If the Bluetooth link is not in the call, the Bluetooth link connected with the vehicle-mounted terminal can be directly switched to the synchronous link; if the vehicle-mounted terminal is in the call, and when the call is monitored to be ended, after delaying a first preset time, switching a Bluetooth link connected with the vehicle-mounted terminal to a synchronous link, wherein the first preset time is 2 seconds as an example. The purpose of the delay is also to ensure that the call has been completely ended, and avoid the occurrence of channel abnormality.
Specifically, the link switching process at least includes: detecting whether a synchronous link is started, and if so, switching to the synchronous link; if not, further judging whether the user terminal supports the synchronous link, if so, starting the synchronous link connection to switch to the synchronous link.
Further, after the bluetooth link connected with the vehicle-mounted terminal is switched to the synchronous link, the successful switching message is fed back to the user terminal in a broadcast mode.
S102, setting the audio mode of an audio manager on the user terminal as a call mode.
Because the voice is transmitted through the synchronous link in the normal call state, and the Audio mode (i.e., Audio mode) of the Audio manager on the user terminal is also automatically set to the call mode during the call, the embodiment of the invention broadcasts the guidance information by using the synchronous link when the broadcast is silent, but the Audio mode is not actually in the call state, so the guidance information can be transmitted by using the synchronous link only by actively setting the Audio mode to the call mode. It should be noted here that, due to different configuration capabilities of the user terminals, the set call modes may also be different. For example, the MODE _ IN _ COMMUNICATION MODE may be used, and the MODE _ IN _ CALL MODE may be used. The embodiment of the present invention is not limited thereto.
And S103, sending the voice data of the current application software on the user terminal to the vehicle-mounted terminal for broadcasting through the synchronous link.
The voice data of the current application software is also the guidance information, such as music or navigation voice, and after the voice data of the current application software on the user terminal is sent to the vehicle-mounted terminal through the synchronous link, the vehicle-mounted terminal broadcasts the received voice data. It should be noted here that sending the voice data of the current application software on the user terminal by using the synchronous link does not affect the user to answer the call, and when the call comes, the user can answer the call and listen to the guidance information at the same time, thereby ensuring that the user can listen to the call while listening to the guidance broadcast.
In the embodiment of the invention, when the vehicle-mounted terminal is silent in broadcasting, the user terminal switches the Bluetooth link connected with the vehicle-mounted terminal to the synchronous link according to the Bluetooth connection setting request of the user, and sets the audio mode of the audio manager to be the call mode, so that the voice data of the current application software on the user terminal is sent to the vehicle-mounted terminal through the synchronous link for broadcasting. Therefore, the condition that the induction broadcast cannot be played due to the vehicle machine fault is ensured, and the user can normally receive the induction information broadcast by the vehicle-mounted terminal. And the induction information is broadcasted through the synchronous link, the answering of the call can be considered at the same time, and the driving safety is improved.
Example two
Fig. 2 is a schematic flowchart of an information broadcasting method based on bluetooth connection according to a second embodiment of the present invention. The present embodiment is further optimized based on the above embodiments, and the volume setting and the related operation of closing the synchronous link are increased.
As shown in fig. 2, the information broadcasting method based on bluetooth connection provided in the embodiment of the present invention may include:
s201, responding to the soundless broadcast of the vehicle-mounted terminal, and switching the Bluetooth link to the synchronous link.
S202, setting the audio mode of an audio manager on the user terminal as a call mode.
S203, the audio stream type of the media player on the user terminal is set as the audio stream for music playing.
The audio STREAM type (StreamType) includes a calling sound (STREAM _ VOICE _ CALL), a SYSTEM sound (STREAM _ SYSTEM), a telephone RING (STREAM _ RING), a MUSIC playing sound (STREAM _ MUSIC), a warning sound (STREAM _ ALARM), and the like, and when a certain type is set, the audio STREAM type (StreamType) is adjusted only for the sound volume of the certain type, so that the influence on the sound volumes of other types can be avoided. For example, if the sound tone is set to be large after STREAM _ MUSIC is set, the volume at the time of the next call is not affected.
In this embodiment, the sound type of the guidance information belongs to MUSIC playing sound, so that before the voice data of the current application software on the user terminal is sent to the vehicle-mounted terminal through the synchronous link for broadcasting, the audio STREAM type of the media player on the user terminal is set to STREAM _ MUSIC, so that it can be ensured that the user can adjust the volume of the broadcast through the volume key of the user terminal.
And S204, sending the voice data of the current application software on the user terminal to the vehicle-mounted terminal for broadcasting through the synchronous link.
In this embodiment, after determining that the guidance information does not need to be continuously broadcasted, the user may trigger the current application software to quit sending the voice data, for example, quit the navigation interface and return to the main interface of the navigation application. And the user terminal executes S205-S206 to finish quitting the induced broadcast according to the monitored user triggering operation.
S205, if the current application software is monitored to quit the operation of sending the voice data, closing the synchronous link.
And when the current application software exits the operation of sending the voice data, closing the synchronous link and recovering to a default channel. Furthermore, in the process of closing the SCO, a phenomenon that some terminals swallow words can occur, so that the broadcast is blocked, and therefore a mute strategy is adopted in the process of closing the synchronous link.
Specifically, if the current audio stream is in the synchronous link, the synchronous link is closed after the volume of the current audio stream type is set to be mute; after keeping silent for a second preset time, which is 2 seconds as an example, the volume of the current audio stream type is restored to avoid silence abnormality.
S206, setting the audio mode of the audio manager on the user terminal to be the original mode.
After the synchronous link is closed and the default channel is recovered, the message of successful switching is fed back to the user terminal in a broadcast mode. The user terminal sets the audio MODE of the audio manager from the call MODE to the original MODE (MODE _ IN _ NORMAL).
Further, after the synchronization link is closed, the type of the audio STREAM of the media player on the user terminal may be set as an audio STREAM for MUSIC playing, that is, set as STREAM _ MUSIC. Thereby ensuring that the volume key can normally adjust the volume.
Further, since there is a situation that the speaker of the terminal is turned off due to a failure of the terminal or the software system, it is necessary to detect whether the speaker of the user terminal is turned off after the synchronous link is turned off in order to ensure that the user uses the terminal normally. If it is detected that the speaker on the user terminal is turned off, the speaker is turned on.
In this embodiment, after switching to the synchronous link, the audio stream type is set to an audio stream for music playing, so as to adjust the volume of the broadcast. And in the process of closing the synchronous link, a mute strategy is adopted, and the phenomenon of broadcasting card pause caused by the word swallowing phenomenon is eliminated. In addition, after the synchronous link is closed, the state of the terminal loudspeaker is detected, and the normal use of the terminal is further ensured.

S308, set the audio STREAM type (StreamType) to STREAM _ MUSIC.
Through the operation, the user terminal switches the Bluetooth link connected with the vehicle-mounted terminal to the synchronous link, and correspondingly sets the Audio mode and the Audio stream type, so that the user terminal can normally transmit the induction information to broadcast through the synchronous link under the condition that the induction information cannot be broadcast due to the vehicle machine fault, and meanwhile, the adjustment of the volume of the induction information broadcast can be supported.

s310, whether a synchronous link is started or not is detected, if yes, S320 is executed, and if not, the operation is finished.
