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,

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,

Hi Nordic team,

I've just received Pixel 7 with LE Audio support and I still cannot connect to any of NRF5340 Audio configurations (headset/gateway, CIS/BIS). Is it possible? Here's the screenshot from NRF Connect application:



Thank you,
Warm regards,

Hi Pavel,

You cannot see the gateway in CIS mode because gateway scans for headsets, does not advertise. However, in BIS mode gateway advertises to other headsets and they should be able to find it and connect to it. 

It is phone that should act as a gateway. Why do you want to use nRF5340 audio DK as a gateway when connecting to the phone? 

Best regards,
Dejan
