Bluetooth AVRC volume control
Posted: Thu May 14, 2020 8:48 am
Hello,
Based on the A2DP_SINK example.
I'm having some issues with the esp_avrc_ct_send_passthrough_cmd to control the bluetooth device's sound volume.
It works with play/stop commands, e.g:
but not for the volume:
I updated my project to IDF v4 (was on 3.3), but same result.
Also tried esp_avrc_ct_send_set_absolute_volume_cmd but it doesn't seem to work either....
Any ideas?
Thanks!
