Problems solved by technology

[0004] However, if only the slave device initiates a connection, there will be some restrictions. For example, when the Bluetooth device as the master device wants to actively communicate with the Bluetooth device as the slave device, but because the master device cannot actively connect to the slave device, the Bluetooth device as the master device The device has to passively wait for the Bluetooth device as the slave device to send a connection request to connect, which will greatly delay the various connections of the Bluetooth device as the master device

Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] The method provided by the invention includes figure 1 The flow shown:

[0039] see figure 1 , figure 1 The flow chart of the method provided by the present invention. This method is applied to bluetooth devices such as figure 1 As shown, the process may include the following steps:

[0040] Step 101, when the bluetooth device is the master device, execute step 102, and when the bluetooth device is the slave device, execute step 103.

[0041]Step 102, determine the candidate master-slave switching time points associated with each bluetooth device as a slave device, check whether there is a conflict between the candidate master-slave switching time points associated with each bluetooth device, when the candidate associated with two blue...

Abstract

The invention provides a Bluetooth device and a mutual searching method thereof. According to the Bluetooth device and the mutual searching method thereof, the identity of the Bluetooth device is not constant, but can be switched automatically, so that automatic search of each adjacent device can be realized, connection with each adjacent device can be built automatically and dynamically based on a service demand, and the connection efficiency is improved.

Description

technical field [0001] The application relates to bluetooth technology, in particular to a bluetooth device and a method for mutual search of the bluetooth device. Background technique [0002] Bluetooth Low Energy (BLE) technology has been widely used due to the advantages of low cost, short distance, interoperability, and working in the license-free 2.4GHz ISM radio frequency band. [0003] At present, devices applying Bluetooth low energy technology (referred to as Bluetooth devices) are divided into master devices and slave devices. Once the master and slave identities of Bluetooth devices are determined, identity modification will not be performed in the future. The Bluetooth protocol stipulates that the master device cannot actively connect to the slave device, and only the slave device can be used as the initiator to connect with the master device. By scanning the broadcast connections sent by the slave devices, the master device can obtain which slave devices exist ...
