I have a problem with the esp32 a2dp sink mode connected to a smartphone. If the smartphone's Bluetooth version is 4.2, connected OK and volume up and down is worked OK. But if the smartphone's Bluetooth version is 5.0, connected OK but volume up and down is not worked.
There is another problem, that module is not auto connected with paired devices.( no version 4.2 & no version 5.0)
My module is ESP32-WROOM32
IDE is Eclipse with esp-idf v4.2
Regards.

I want to know , that this issue is limitation of hardware or bug of firmware and libraries.
Is that for Bluetooth 4.2 device?
Thanks.
