Problems solved by technology

However, this way of initiating a connection back is prone to connection failure. For example, while the peripheral device is paging (page) the central device, the central device may also initiate a page to the peripheral device. The two page requests will collide, causing the Bluetooth connection to fail.

Abstract

The invention discloses a Bluetooth reconnection method and a related device, the method is applied to a Bluetooth connection system, and the Bluetooth connection system comprises a first device and asecond device. The method comprises the steps that after Bluetooth connection of the first device and the second device is disconnected, the first device sends a BLE broadcast signal to the second device; if the second device determines that the received broadcast signal is the first BLE broadcast signal, the second device does not need to page the first device and waits for receiving a page datapacket sent by the first device; and if the second device determines that the received broadcast signal is the second BLE broadcast signal, the second device actively pages the first device, and thefirst device waits for receiving a page data packet sent by the second device. In this way, the problem of page request collision caused by the fact that the second device and the first device initiate pages at the same time can be avoided, and the success rate of Bluetooth reconnection is increased.

Description

technical field [0001] The present application relates to the field of electronic technology, and in particular to a Bluetooth connection back method and related devices. Background technique [0002] Bluetooth (Bluetooth) is a commonly used data transmission method in people's lives. It can realize short-distance wireless transmission of data between electronic devices (such as mobile terminals, notebook computers, wireless headsets, handheld computers, etc.), which is convenient, fast, Advantages of flexibility and security. Generally, as the distance between electronic devices connected with Bluetooth increases, the Bluetooth connection may be disconnected. [0003] In the prior art, in the case that the Bluetooth connection is disconnected due to non-human operation, in order to restore the Bluetooth connection, peripheral devices (for example, wireless earphones, smart speakers, smart watches, etc.) will contact the connected central device ( For example, a mobile ter...
