nRF5340, Audio transmission delay between 2 peripherals (Tx1 and Tx2)

[tommy]

We could have found "transmission delay" in 2ch Audio recording sequence.

Here are the detail about the environment of DUT, and phenomenon.

Please find the attached file.

 

Would it be possible to let us know the possible cause of this delay?

 

We are using ver2.3.0 as NCS.

In addition, this phenomenon has been found in our pre-production model.

And if you can suggest any test environment provided by nordic's EVK to immitate, it would be highly appreciated.

Hello,

I just had a discussion with our R&D and was informed that this has already been discussed directly with them.. In short, we don't have synchronization mechanism for L and R send back to the central.. Synchronization only happens on the headset side.. It was informed to us that Canon will upgrade the SDK shortly.. But even then, this is a missing feature.

Best Regards,

Swathy
