Disclosed are systems and methods to modify the Bluetooth mono HFP protocol to support bi-directional stereo operation for high bandwidth audio including 12-KHz wide-band, 16-KHz super wide-band (SWB), and 24-KHz full band (FB) audio. The techniques leverage the larger packet size and longer duty cycle of the 2-EV5 transport packet and expand the block size of the audio frames generated by the AAC-ELD codec to increase the maximum data throughput from the 64 kbps of the mono HFP protocol to 192 kbps using a stereo HFP protocol. The increased throughput not only supports stereo operations, but allows the transport of redundant or FEC packets for increased robustness against packet loss. In one aspect, the AAC-ELD codec may be configured for dynamic bit rate switching to flexibly perform trade-offs between audio quality and robustness against packet loss. The stereo HFP may configure the maximum throughput based on the desired audio quality.

Disclosed in the embodiments of the present application is a headset communication system. The headset communication system comprises: a bone conduction headset, comprising a first Bluetooth module; an intercom device, comprising a first external interface; an external communication module, comprising a second external interface and a second Bluetooth module.

A BLUETOOTH communications system includes a true wireless stereo (TWS) BLUETOOTH headset and a terminal device, where the TWS Bluetooth headset includes a first earbud and a second earbud. The terminal device controls the first earbud to collect a sound signal and the second earbud to play a sound signal. When an audio application on the terminal device is started, the first earbud collects a first sound signal, performs sound effect processing on the first sound signal to obtain a second sound signal, and sends the second sound signal to the second earbud. The terminal device sends accompaniment audio to the second earbud, and the second earbud performs audio mixing processing on the accompaniment audio and the second sound signal for playing.

This application discloses a Bluetooth reconnection method, and relates to the field of short-range wireless communications technologies. The method includes: When a charging case is closed, a first earbud breaks a Bluetooth connection, where the first earbud stores a Bluetooth address of a terminal and a Bluetooth address of a second earbud. When the charging case is opened, the charging case accommodates only the first earbud, and a first preset condition is met, the first earbud sends a first paging request to the second earbud based on the Bluetooth address of the second earbud. The first preset condition is that the Bluetooth connection includes a Bluetooth connection between the first earbud and the second earbud. In this way, reconnection duration of the first earbud when the charging case is opened can be reduced.
