Input_key_listener and audio_event_iface_listener don't work simultaneously?!
Posted: Sat Oct 14, 2023 1:30 am
Hi there,
I was trying to implement an audio player like the one in examples/player/pipeline_sdcard_mp3_control example that can stream the audio to a bluetooth sink like examples/player/pipeline_a2dp_source_stream.
For this i need the 4 buttons Play,Set,Volup, Voldown which are handled by the Input_key_listener like this:
1.
2.
3. where "input_key_service_cb" is the custom callback function.
This works fine unless I also set an audio event listener. I do this with the following lines of code:
1.
2.
I only use this audio event listener just for some Bluetooth_events! However it also listens for button events because the buttons are also an esp_peripheral and need to be initialised and started for the input_key_service to work with the "esp_periph_set_handle_t set".
As soon as the "audio_event_iface_set_listener(esp_periph_set_get_event_iface(set), evt);" line is called, the input key listener from above doesn't work anymore.
Does anyone have a solution for this?
Or am i missing something obvious here?
