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,
Rajendra.

Check out this post  nRF5340 Audio - configure gateway unit also as ACL peripheral  

We are currently understaffed due to the summer vacation period, so delayed replies must be expected. I am sorry about any inconvenience this might cause.

Hi Amanda Hsieh,

Issue: Mismatched Service UUIDs in BLE Communication Between nRF5340 Audio DK and nRF5340 DK

I have tried to establish BLE communication between the nRF5340 Audio DK and nRF5340 DK, but the services are not matching.
The nRF5340 Audio DK uses a 16-bit service UUID, while the nRF5340 DK uses a 128-bit service UUID.
This discrepancy is preventing successful communication between the two device.

Warm Regards,
Rajendra

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.
