Send audio data to Bluetooth Earbuds

[RickLloyd24]

Thank for the great library. I am using an ESP32 WROOM and would like to send audio to some TOZO earbuds. It seems the best example is "communication-ble-server-send.ino".

When I compile the example,, I get the following 2 error messages.

C:\Users\rickl\OneDrive\Documents\Arduino\libraries\arduino-audio-tools\src/Sandbox/BLE/AudioBLEServerESP32.h:111:16: error: 'class BLECharacteristic' has no member named 'notifyAudioChange'
info_char->notifyAudioChange();
^~~~~~~~~~~~~~~~~
C:\Users\rickl\OneDrive\Documents\Arduino\libraries\arduino-audio-tools\src/Sandbox/BLE/AudioBLEClientESP32.h:259:18: error: 'class BLERemoteCharacteristic' has no member named 'registerFornotifyAudioChange'; did you mean 'registerForNotify'?
info_char->registerFornotifyAudioChange(notifyCallback);

              ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
              registerForNotify

Any help or suggestions would be greatly appreciated.

I think you are confusing here something: The ESP32 does not support any official BLE Audio Standard

I thought I could do it in software. Still learning Bluetooth.

It would work if you have headphones that support Bluetooth A2DP.

BLE Audio is not working...

The earbud manufacturer says they support A2DP. Do you know why I am getting the compile errort?

I committed a correction: you will need to install the updated version...

Thank you, I will try to get it to work.

You will need to use the A2DP examples and not the BLE ones
