Embodiment Construction

[0023] Classic Bluetooth and Bluetooth Low Energy work in different modes, using time-division multiplexing to work. In the dual-mode scheduling process, in order to prevent the connection event (Connection Event, CE) of Bluetooth low energy from being occupied by the synchronous link data packet of classic Bluetooth, the CE of Bluetooth low energy can be predicted to switch to low power in advance. Consumes bluetooth mode. However, in most cases, the received synchronous link data packet of classic Bluetooth is a short-slot packet, for example, the received synchronous link data packet is only a 1-slot packet. Switching from the Bluetooth mode to the Bluetooth low-power mode will result in waste of time slot resources in the existing switching method.

[0024] In the embodiment of the present invention, when the current synchronous link data packet receiving operation of the classic Bluetooth is performed, the time slot length occupied by receiving the synchronous link data ...

Abstract

The invention provides a bluetooth data reception control method and apparatus. The method includes when the synchronous link data packet in the classic Bluetooth mode is received, acquiring the time slot occupied by the current synchronous link data packet from the packet header of the currently received synchronous link data packet; and when a connection event in a low-power Bluetooth mode is detected within the slot length, abandoning the current synchronization link data packet and switching to a low-power Bluetooth mode to receive the connection event of a low-power Bluetooth. According to the method and apparatus, the waste of time slot resource can be effectively prevented.

Description

technical field [0001] The invention relates to the field of bluetooth communication, in particular to a bluetooth data receiving control method and device. Background technique [0002] In Bluetooth 4.0 and subsequent protocols, there are two parts: Classic (Classic) Bluetooth and Low Energy (LowEnergy, LE) Bluetooth. The Bluetooth low energy protocol was introduced in the Bluetooth 4.0 protocol, and the maximum length of data in a data packet is 39 bytes (byte), which is transmitted at a rate of 1Mbps (megabits per second). The data length in the classic Bluetooth data packet is up to 1023 bytes, and the transmission rate can be 1Mbps, 2Mbps and 3Mbps. [0003] Classic Bluetooth and Bluetooth Low Energy work in different modes, using time-division multiplexing to work. In the dual-mode scheduling process, in order to prevent the connection event (Connection Event, CE) of Bluetooth low energy from being occupied by the synchronous link data packet of classic Bluetooth, th...
