CIS bidirectional communication / nrf5340 audio

Hello Team,

NCS: V2.2.0

I am using three nrf5340 audio dk to test bidirectional ble audio application. I have added CONFIG_WALKIE_TALKIE_DEMO=Y in the prj.conf file.

When I was testing CIS bidirectional communication, I found that the audio is streamed only to one nrf5340 audio DK (configured as left). The gateway does not communicate with the nrf5340 Audio DK which was configured to output right channel data.  The LED1 on the gateway and Audio DK (configured as left) lights up, but the LED1 on the Audio DK (configured as right) does not light up and stream audio. 

Document states that "Only one headset can be connected when using the bidirectional mode or the walkie-talkie demo.

What does the "headset" means here? A TWS or a mono stream supported headphone?

Can't I stream bidirectional audio using a common TWS configuration using both Audio DK configured as Left and Right? 

Thanks in advance.

Best regards,

Adarsh
