Bluetooth data interaction method and Bluetooth device

Abstract

The invention discloses a Bluetooth data interaction method and a Bluetooth device, wherein the method comprises the following steps: detecting whether a Bluetooth connection between a slave device and a master device is interrupted in real time; if that Bluetooth connection between the slave device and the master device is interrupted is detected, caching all the packet data in a cache region bya Bluetooth on the slave device, wherein the packet data comprises to-be-transmitted packet data and the packet data which is not completely transmitted; through a Bluetooth antenna on the slave device, broadcasting identification information of the salve device to the master device which is in Bluetooth connection ever before the connection is interrupted; and after the slave device newly buildsa connection with the master device, continuing to perform packet data interaction with the master device according to the packet data cached in the cache region. In the embodiment of the invention, after the Bluetooth connection is interrupted, rapid reconnection can be realized, data packet breakpoint resume can be realized, and reliability of data interaction in Bluetooth connection is promoted.

Description

technical field [0001] The invention relates to the technical field of bluetooth communication, in particular to a bluetooth data interaction method and a bluetooth device. Background technique [0002] Bluetooth Low Energy (BLE) devices communicate at low data rates / intermittently, but require high data reliability scenarios. In this scenario, the following limiting factors need to be considered at the same time: low power consumption, which cannot significantly destroy the low power consumption characteristics of Bluetooth; intermittent, that is, there may be uncertain disconnections or lost connections between the Bluetooth device and the Bluetooth host Situation; Reliability, that is, in the case of uncertain connection, it is necessary to ensure that the data interaction between the Bluetooth device (BLE Slave) and the Bluetooth host (BLE Master) can continue without loss at a low data rate. [0003] However, on the basis of the existing technology, it is often possibl...

Problems solved by technology

[0003] However, on the basis of the existing technology, it is often possible that due to the lack of penetrability in the Bluetooth signal transmission process, the Bluetooth connection is likely to be dropped during the Bluetooth connection data transmission interaction process between the device and the device. After the line is reconnected, it cannot effectively realize the breakpoint resume transmission of data transmission interaction, etc.
