Embodiment Construction
[0023] As mentioned in the background technology, HFP describes how to use mobile phone devices to make and receive calls in hands-free Bluetooth devices. Using HFP, mobile phones with Bluetooth functions can be allowed to be placed in pockets, cars, briefcases, etc. And use the hands-free bluetooth device to realize the call function. A2DP describes how to stream stereo audio from an A2DP playback device to a Bluetooth device. A2DP can support a variety of specific codec methods. When a Bluetooth device is connected to multiple HFP devices and A2DP devices, there is a problem of device connection priority. In this embodiment, the Bluetooth device will connect with the device according to the priority of the protocol. According to HEP, since connecting with HEP devices should be the first priority, configure Bluetooth devices to first search for HPF devices (such as mobile phones) and try to connect to them, while standalone A2DP devices (such as MP3 players) will have secon...
