friends,
i am new to esp32.. i am interested in bluetooth and am trying to develop Bluetooth speaker with lcd display.. i just want to display the tracks playing and the number if any calls.
1. Is that possible without any special app.. by
just pairing esp32 and android phone like in
various company music systems.
2. how to change bluetooth symbol when paired.
and add a headphone symbol?
3. another doubt is what kind of Bluetooth communication is used in nowadays Bluetooth headset...? is it classic Bluetooth or BLE?
Please help folks..
