Not able to connect nRF5340 LE Audio to Android

[Paveletu]

Hi support team! I hope you're well.

I'm trying to connect nRF5340 Audio DK (gateway) to my Pixel 6a. The problem is there's no `NRF5340_AUDIO` detected via Bluetooth when I flash the sample in CIS mode and in BIS mode it's detected but cannot be connect (please find a screenshot from nRF Connect application attached).

Is there any way to make nRF5340 connectable to a phone?

Also, does my phone require to have a "LE Audio" supported chipset (like the once listed here: www.qualcomm.com/.../bluetooth-le-audio) on it to even be connected? Will Bluetooth 5.2 and OS support (Android 13 has support for LE Audio profile) not be enough?

As a side note my question is very similar to this one: https://devzone.nordicsemi.com/f/nordic-q-a/91856/nrf5340-audio-dk-connection-to-phone

Many thanks,
Warm Regards,
Pavel

Hi Pavel, Dejan,

I can confirm that i am seeing the same as this issue. when the gate way is programmed to NCS v2.1.0-rc2 using the python build script, The gateway is not visible, however I assume this is because it is scanning for the headset and not advertising.

I have also tried the headset, and this is visible, and I can see all the services with the latest Build. but as soon as I pair via the android OS everything disappears and the device is not able to be connected on the phone again until it is reprogrammed and cannot be used as a headset.

I have the same issue in the NRF app suggesting I don’t have LE Audio capabilities, Mobile is a Oneplus 10 Pro processor:  Snapdragon 8 Gen 1 – which has a Bluetooth 5.3 stack and Android 13 which is LE audio compatible to my knowledge.

Regards

Jack

Hi,

Could you please check the behavior with NCS v2.1.0?

Hi,

Regarding LE Audio support, it might be the case that mobile vendor has not enabled the LE Audio feature in your phone (in public release) and nRF Connect App reports that.

Thank you for backing me up on this question, Jack!

Thank you, Dejan! It makes sense. Still surprised there's no detection at all in CIS mode. Fingers crossed, the new Pixel 7 will support LE Audio and allows us to test nRF5340 Audio DK in the real life scenario

Warm Regards,
