Using BLE audio examples for nrf5340 audio DK, with a smartphone

[Chillypaste_bandit]

Provided examples works when nrf5340dk boards working as source and sink, but any examples that implements an android phone as source and nrf5340 audio dk as source?. Like when making a bluetooth speaker using nrf5340 audio dk that plays audio from smartphone over BLE?

Hi,

First of all, the audio application must be built in CIS unidirectional mode (with CONFIG_TRANSPORT_CIS set to y and CONFIG_AUDIO_DEV set to 1). This is the default when building nRF5340 Audio: Unicast server, so you do not need to change prj.conf if you are running the application out of the box.

Once you have programmed the nRF5340 Audio DK, it should advertise as NRF5340_AUDIO, and you should be able to see and connect to it using your phone's native Bluetooth settings. After connecting to it, enable Le Audio in the device settings. When you have done this, you should be able to play audio from your phone on the nRF5340 Audio DK.

Best regards,
Marte

thanks Marte Myrvold  got it ! . I ran the unicast example, seemingly the issue was my phone(S22) wasn't supporting LC3, though it connects doesn't show up as an audio device. Gonna try with a newer phone. Also what are the solutions if we are using ios products? is there a workaround(AAC implementation) until apple decides to implement LC3?

Hi,

There is no workaround. I suggest that you contact vendors directly to get the status of their LE Audio support.

Hello Marte,

I'm testing this scenario using a Motorola Edge 50 Pro phone with Android 14.

I can pair my phone to the nrf5340 Audio DK board and enable LE Audio but I still can't hear anything from my wired earphones with a 3.5mm jack connected to HEADPHONE jack on the board.

I can play/pause streaming application (e.g youtube music) and increase and decrease volume with VOL+ and VOL- buttons

But no music from the headphones connected. Did i miss something?

Thanks.

Regards,

Daniele
