How to communicate the nRF5340 DK and the nRF5340 Audio DK over BLE.

[RajendraN]

Hi,

I am currently working on communicating between the nRF5340 DK and the nRF5340 Audio DK over BLE. Could you please share the information flow?

Warm regards,
Rajendra.

Hi, 

You can use the 'ACL' which runs alongside the ISO to control the stream as a regular BLE connection. Please be aware of the current limitation of Softdice Controller concurrently supporting 2 ISO + 2 ACLs, which means you could do 2 ACL + 2 BIS, or 2 CIS (since 1 CIS requires both 1 ACL and 1 ISO).

See an example of how quickly/easily additional services can be added to the nRF5340 Audio reference application here.

Hi amanda,

I am a beginner at Nordic. Could you please give me more information and any source code or video communication.

Warm Regards,

What service did you add to the audio application? 

What service would you want to connect on the nRF5340DK?

Hi Amanda,


Thanks for response,

I'm successfully communicating between the nRF5340 DK (GATEWAY) and the nRF5340 Audio DK (HEADSET) over BLE.
However, when I try to share the audio stream from the GATEWAY to the HEADSET, I'm getting a beep or sinusoidal sound on the nRF5340 Audio DK.

How can I correctly transmit the audio data to the nRF5340 Audio DK.

Could you please guide me on this.

NOTE: ADDED EXTERNAL MIC ON NRF5340 DK


Warm Regards,
Rajendra.

Hi, 

The latest issue is away from the original issue. Please create a new support case.

Hi Rajendra,

I'm too trying to configure nRF5340 DK as a GATEWAY as my other device is a nRF5340 AUDIO DK running as a HEADSET. I tried in many ways but, I failed to configure the nRF5340 DK as a GATEWAY. Its good to know that you are successful in the attempt. Could you tell me the sample file you used for this? I tried with central_uart BLE sample but, it was of no use. 

Please guide me on this. 

Thanks & Regards,

Lalith.
