Esp-idf: I cannot use AVRCP mode without initializing A2DP (IDFGH-580)

[Marc-Aurele]

I want to use only the AVRCP mode so i started with the following example : a2dp_gatts_coex
When i flash it onto my board, here is the ouput of bluetoothctl :

[bluetooth]# info 20:47:DA:FB:93:65
Device 20:47:DA:FB:93:65 (public)
    Name: ESP_COEX_A2DP_DEMO
    Alias: ESP_COEX_A2DP_DEMO
    Class: 0x002c0414
    Icon: audio-card
    Paired: no
    Trusted: no
    Blocked: no
    Connected: no
    LegacyPairing: no
    UUID: Audio Sink                (0000110b-0000-1000-8000-00805f9b34fb)
    UUID: A/V Remote Control Target (0000110c-0000-1000-8000-00805f9b34fb)
    UUID: A/V Remote Control        (0000110e-0000-1000-8000-00805f9b34fb)
    RSSI: -50

That is working nicely enough so far - but now I want to get rid of the A2DP-part. My intuition was to just remove the esp_a2d_

I would have expected to now only see the UUIDs for "A/V Remote Control" - but there is just no UUIDs at all.

Hi,

Is there someone who has already worked on a workaround for this issue. I really need AVRCP without AD2P ? If you have any idea, feel free to share :)

Best regards,

Here is the kind of configuration i want :

Do you think it is possible with the current library ?

Please help answer this question, thanks.

@Marc-Aurele Sorry to tell you that we can't use AVRCP without A2DP, now.

Hi @blueMoodBHD
Thank you very much for the reply. Indeed, we were suspecting that, as a result, we have switched on HID over GATT profil.
