Add peripheral support with BIS enabled.

JimmyOu

Hi,

I am currently working with the nRF5340 Audio DKs and have successfully implemented the gateway and handset functionalities.

Now, I want to extend the system by enabling the peripheral role and GATT services to modify the broadcast information.

I've attempted to configure this by adjusting the relevant settings and connection intervals, but I haven't had success so far.

Additionally, when I connect the device to my S23, it seems to time out easily.

Your assistance would be greatly appreciated.

Thank you.

    Hi Maria,

    Sorry, I haven’t tried that with nRF Connect SDK v2.9.0 yet.

    I'll try it once I have time.

    Thanks for your reply.

    Best regards,
    Jimmy
