Hello! post #3 has mentioned Classic bluetooth (Bluetooth to serial example) SerialBT.begin("ESP32test"); //Bluetooth device name.
I have the same problem as the spikespiegel's post. Windows 10 don't find SPP bluetooth of the ESP32....
Before, I used Bluetooth LE Explorer software to check Bluetooth characteristics, service names, etc (laptop can find BLE by Bluetooth LE Explorer) .
@spikespiegel Have you solved the problem yet?
