However, CIS / BIS is also a periodic reservation time slot, which also occupies more time slot bandwidth, so TWS+CIS / BIS multi-connection will make the Bluetooth time slot bandwidth of the TWS master and slave more congested and even insufficient

[0018] combine figure 1 As shown, a bandwidth improvement method of a Bluetooth audio system includes:
[0019] Step S1, build a TWS monitoring system, the TWS monitoring system includes a gateway, a TWS host and a TWS slave, wherein the gateway establishes a first link with the TWS host, the TWS host establishes a second link with the TWS slave, and the TWS host passes through the second link. Send the connection information of the first link to the TWS slave, and the TWS slave establishes a TWS monitoring service link for monitoring the data packets sent by the gateway to the TWS host;
[0020] Step S2, after the gateway sends the data packet to the TWS host, the TWS host sends the packet to the gateway according to the receiving state of itself and the TWS slave, and the TWS slave performs the non-listening service in the time slot of monitoring the packet sending of the TWS host, and the non-monitoring service is the TWS slave. The service selected by the scheduling syste...

The invention discloses a bandwidth improvement method of a Bluetooth audio system, which relates to the field of wireless Bluetooth technology, including: building a TWS monitoring system, the TWS monitoring system includes a gateway, a TWS host and a TWS slave, wherein the gateway and the TWS host establish a first link. , the TWS master establishes a second link with the TWS slave, the TWS master sends the connection information of the first link to the TWS slave through the second link, and the TWS slave establishes a TWS monitoring service link for the monitoring gateway to send to the TWS The data packet of the host; after the gateway sends the data packet to the TWS host, the TWS host sends the packet to the gateway according to the receiving status of itself and the TWS slave, and the TWS slave executes the non-monitoring service in the time slot of monitoring the packet sent by the TWS host. Use the slave to monitor the host's TX time slot, send and receive non-monitoring services, improve the system's time slot bandwidth capacity, and improve the bandwidth performance of TWS+ non-monitoring services.
Description
technical field [0001] The invention belongs to the technical field of wireless bluetooth, in particular, to a method for improving the bandwidth of a bluetooth audio system. Background technique [0002] TWS (True Wireless Stereo true wireless stereo) system can be divided into two categories of services according to the link: TWS non-monitoring services and TWS monitoring services. The Bluetooth TWS monitoring system generally consists of a gateway (mobile phone tablet device), a TWS host and a TWS slave (including but not limited to Bluetooth monitoring team devices such as headphones and speakers). At present, the mainstream TWS headsets use the monitoring scheme of the TWS slave. After the TWS host establishes a connection with the mobile phone, the TWS host sends the connection information to the TWS slave through the connection between the TWS host and the TWS slave, so that the TWS The slave machine can monitor the packets sent by the gateway to the TWS host, so tha...
