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...

Abstract

In order to solve the problem of selection of a Bluetooth device provided with a plurality of input sources, the invention provides a method for pairing and connecting multiple devices and the Bluetooth device. A memory is arranged in the Bluetooth device, and a plurality of pairing device lists are stored in the memory. The method comprises the steps as follows: searching is performed, so that an HFP (hands-free profile) device in the pairing device lists is looked for; when the HFP device exists in the pairing device lists, the Bluetooth device attempts to establish connection with the HFP device; searching is performed, so that A2DP devices in the pairing device lists are looked for, and connection is attempted to be established; the Bluetooth device is connected to a first A2DP device, then the Bluetooth device searches a second A2DP device in the Bluetooth pairing list, and the Bluetooth device attempts to establish connection with the second A2DP device; and the Bluetooth device is arranged into a non-discoverable mode after connected to the second A2DP device.

Description

technical field [0001] The present invention relates to a method for pairing and connecting a plurality of devices with a bluetooth device, in particular, a method for connecting a plurality of A2DP devices and HFP devices with a bluetooth device. Background technique [0002] Bluetooth is a short-range wireless communication technology. Electronic devices can be connected to each other through a Bluetooth module, eliminating the need for traditional wires. Through the wireless receiver on the chip, electronic products equipped with Bluetooth technology can communicate with each other within a distance of ten meters, and the transmission speed can reach 1 megabyte per second. At the same time, Bluetooth supports short-distance communication of devices (generally within 10m). It can exchange information wirelessly between many devices including mobile phones, PDAs, wireless headsets, notebook computers, and related peripherals. The Bluetooth standard is IEEE802.15, which wo...
