Problems solved by technology
[0003] In the existing solution, the earphone responsible for connecting and forwarding consumes more power, and the actual battery life is greatly reduced. Due to the limitation of sending and receiving mode A, when forwarding information, it will not be able to receive information for a short time, and there will be certain information interruption and Delay, and the connection compatibility with smart devices is poor. After A is disconnected, B needs to reconnect to continue to receive new information, so B's music will be interrupted for about a few seconds. This method can only realize two devices sharing music

Embodiment Construction
[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0018] see figure 1 , in the embodiment of the present invention, a signal sharing connection method based on Bluetooth communication, the first connected Bluetooth device A sets about 50ms to broadcast connection information and audio synchronization information through Optek Link, other devices (can be expanded to 3) Receive connection information and audio synchronization information and establish a connection with the mobile phone, which can realize audio ...

The invention discloses a signal sharing connection method based on Bluetooth communication. The Bluetooth device A in the first connection sets 20-100 ms broadcast connection information and audio synchronization information through Optek Link, and other devices (which can be extended to three) establish connection with a mobile phone after receiving the connection information and the audio synchronization information, so that audio information sharing can be achieved; and a control command (such as a key command, pause and the like) of the B can be transmitted to the A, and the A feeds the control command back to the intelligent terminal to achieve control. Multi-path connection (at most four paths) can be achieved through the sharing mode, compared with a traditional mode, connection ofthe mode A earphone and other earphones involved in the invention is real connection rather than forwarding, so that power consumption is reduced, compatibility is changed, endurance is more durable,and interruption of received information and delay protection points are avoided through the sharing technology.
Description
technical field [0001] The invention relates to the technical field of bluetooth communication, in particular to a signal sharing and connection method based on bluetooth communication. Background technique [0002] As the current mainstream wireless transmission technology, Bluetooth headset has a wide range of applications. Through this technology, it mainly solves the problem of sending and receiving short-distance information, and is no longer limited by the quality of the Internet network. For the needs of practical applications, Bluetooth communication The technical requirements are getting higher and higher, and the demand for multiple people to connect to the same smart terminal at the same time is also increasing. At present, there are few multi-channel Bluetooth device connections on the market. The conventional connection method is realized by forwarding, that is, smart terminals and Bluetooth After the headset A is successfully paired, the Bluetooth headset A for...
