Problems solved by technology

However, it has been found in practice that if the time slice round-robin scheduling method is used to schedule the link state, in the case of scheduling conflicts in the link layer, the time duty cycle of the link layer state with low priority will be reduced, which will affect the corresponding link state. The execution of the business, which in turn affects the realization of the application corresponding to the link state in the Bluetooth host, and reduces the experience of using Bluetooth low-power devices

Abstract

The invention discloses a Bluetooth communication method and device supporting a multi-antenna transceiving channel, the method is applied to a Bluetooth device, and the method comprises the following steps: setting a state identifier corresponding to each target state in a link layer of the Bluetooth device according to all started applications in the Bluetooth device; judging whether a scheduling conflict exists in the link layer or not according to the state identifiers corresponding to all the target states; and when the scheduling conflict exists in the link layer, opening a plurality of antenna transceiving channels of the Bluetooth device. Visibly, when the link layer multi-state of the Bluetooth device is effective, the scheduling conflict of the link layer can be reduced by opening the multiple antenna transceiving channels, so that the situation that part of services cannot be executed or are delayed to be executed is reduced, and smooth execution of all services in the Bluetooth device is ensured. And the scheduling queue of the antenna transceiving channels can be shortened by opening the plurality of antenna transceiving channels, so that the execution efficiency of services in the Bluetooth device is improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a Bluetooth communication method and device supporting multiple antenna transceiving channels. Background technique [0002] In real life, Bluetooth is widely used in information transmission as a short-range wireless connection technology, and Bluetooth low energy consumption is one of the modes of Bluetooth. Due to its extremely low power consumption, it is widely used in the field of Internet of Things, Small data transmission field. [0003] Bluetooth low-power devices are usually composed of a Bluetooth host and a Bluetooth controller. The Bluetooth host is used to implement Bluetooth applications and includes a combination of various standard application protocols. The Bluetooth controller includes a link management module, a baseband and link control module, and a modem Tuning module, RF front end. When the Bluetooth host starts an application, the Bluetooth contro...
