Problems solved by technology

When using Bluetooth technology for business data transmission, each type of data can contain control data and user data of the same business, and can also contain data of different businesses. However, the urgent need for scheduling transmission of control data, user data and data of different businesses In this way, the Bluetooth control layer can only process these data according to the principle of first arrival, first processing, which may cause some urgent data not to be processed in time, resulting in business freeze or connection link disconnection

Abstract

The embodiment of the invention discloses a data transmission method and a related device. The method comprises the following steps that according to the priority of data to be sent, the electronic equipment transmits the data to be sent to a logic channel of the priority; and when the electronic equipment triggers an air interface data packet transmission event, to-be-sent data of the logic channel with the highest priority is selected from all the logic channels with the priorities to be packaged and sent. Therefore, the electronic equipment can perform priority packet transmission on the to-be-transmitted data of the logic channel with the highest priority, so different service quality requirements are met.

Description

technical field [0001] The present application relates to the technical field of Bluetooth communication, in particular to a data transmission method and a related device. Background technique [0002] At present, in the Bluetooth standard protocol, the Bluetooth protocol stack includes two parts: the Bluetooth host HOST and the Bluetooth control layer Controller, and the data between the Bluetooth host and the Bluetooth control layer is divided into asynchronous connectionless (Asynchronous connectionless, ACL) data, synchronous (Synchronous Data, SD) data and network layer protocol data three types of data. When using Bluetooth technology for business data transmission, each type of data can contain control data and user data of the same business, and can also contain data of different businesses. However, the urgent need for scheduling transmission of control data, user data and data of different businesses The characteristics may be different. In this way, the Bluetooth...
