Hi,

Have been usung the ESP32 with the Arduino Bluetooth Classic SerialToSerialBT.ino example and getting data sent both ways using the Android App - Serial Bluetooth Terminal 1.31 by kia-morich.

However if I try running the SerialToSerialBTM Example, which seems to have a PIN system, it fails to connect and never asks for the Pin code when pairing.

Have looked around the web and Espressifs forum, seems this is a problematic area .

Does anyone have some proven code they could share that does work with a PIN or give me a clue as to what I am doing wrong !

thanks.
