Hi Team,
I currently need to use the device CC85DK-Headset to realize the uplink function in which one CC85XXDK-Headset should be connected to 2 Bluetooth devices. How should I configure it?
Kind regards,
Katherine

Hi Katherine,
The CC85XX uses proprietary radio communication which does not support the Bluetooth Specification or protocol. The maximum slave count can be increased from the Analog Input Master's Radio Module of the PurePath Wireless Configurator.

Hi Ryan,
Could you specify how to configure the master and slave of the application role? For the master, I have set the maximum number of radio slaves to 2, but when I use two slaves to communicate with the master, there is only one slave that can transmit the sound to the host. When I power off the slave that can transmit audio, another slave can transmit sound.
Below is my configuration information.

Katherine
Hello Katherine,
You will need to use Mono microphones for your slave configuration, otherwise one slave will require both upstream audio channels. See these relevant E2E threads for more information.

Hi Ryan,
After I configure and modify according to https://e2e.ti.com/f/1/t/777057, currently only one slave (logical channel: Microphone0) can transmit audio, and the other slave (logical channel :Microphone1) is unable to transmit. Below is my configuration:
Host:
Slave 1:
The modifications that I made to Slave 2:
For slave 2, I changed the logical channel to Microphone1.
At present, according to this configuration, slave 2 cannot transmit data. I think I only need to change the I2S channel to RIGHT. But there is no way to modify this.
For the above configuration, the uplink 1 drag 2 function cannot be realized. How to modify the current configuration?

Katherine
Using bidirectional audio allows for LEFT/RIGHT I2S channel configurations for both master and slave devices. Please be aware that I have not tested this configuration so although the project does not have any errors I am unsure as to the results

Thank you so much. I used bidirectional audio and the communication was successful.

Katherine
