* esp32-hal-bt.c free Bluetooth LE memory if CONFIG_BTDM_CONTROLLER_MODE_BR_EDR_ONLY is set BLE memory can be released if bluetooth-classic - only is requested * tStart( add error output * ble mem_release only for esp32 * disable BLE with BT_MODE define * BluetoothSerial add begin()+disableBLE; add memrelease * btStart with BT_MODE parameter * beautification * Update BluetoothSerial.cpp fix wrong merges --------- Co-authored-by: Me No Dev <me-no-dev@users.noreply.github.com>
