Multi-member Bluetooth device, and related primary Bluetooth circuit and secondary Bluetooth circuit

Abstract

The application relates to a multi-member Bluetooth device, and a related primary Bluetooth circuit and a secondary Bluetooth circuit. A multi-member Bluetooth device for communicating data with a remote Bluetooth device is disclosed including: a main Bluetooth circuit and an auxiliary Bluetooth circuit. In the period during which the auxiliary Bluetooth circuit operates at a sniffing mode, the auxiliary Bluetooth circuit sniffs packets transmitted from the remote Bluetooth device while the main Bluetooth circuit receives packets issued from the remote Bluetooth device, and the auxiliary Bluetooth circuit switches from the sniffing mode to a relay mode if the throughput of packets sniffed by the auxiliary Bluetooth circuit is lower than a predetermined threshold. In the period during which the auxiliary Bluetooth circuit operates at the relay mode, the main Bluetooth circuit receives packets transmitted from the remote Bluetooth device and forwards the received packets to the auxiliary Bluetooth circuit, and the auxiliary Bluetooth circuit does not sniff packets issued from the remote Bluetooth device.

Description

technical field [0001] The invention relates to bluetooth technology, especially a multi-member bluetooth device capable of adaptively switching operation modes in response to changes in received packet data types, and a main bluetooth circuit and a secondary bluetooth circuit used in the multi-member bluetooth device. Background technique [0002] A multi-member Bluetooth device refers to a Bluetooth device composed of a plurality of Bluetooth circuits that are used in conjunction with each other, for example, a pair of Bluetooth earphones, a group of Bluetooth speakers, and the like. When the multi-member Bluetooth device is connected with other Bluetooth devices (hereinafter referred to as remote Bluetooth devices), the remote Bluetooth device will treat the multi-member Bluetooth device as a single Bluetooth device. When a traditional multi-member Bluetooth device operates, one of the member circuits is set as the main Bluetooth circuit, which is responsible for two-way ...

AI Technical Summary

Problems solved by technology

[0004] When the data type of the packet sent by the remote Bluetooth device changes, if the collocation operation between the main Bluetooth circuit and the secondary Bluetooth circuit cannot be adjusted adaptively, it is easy to reduce the overall operating performance of the multi-member Bluetooth device, reduce the standby time, and cause usage Inconvenience or even inability to complete certain operations (for example, firmware updates)
