Possible solution if unable to connect Windows with ESP32 board via Bluetooth

[progen]

I registered for an account specially to tell other users who might be facing the same problem but have yet to find a solution.

This is what you can try if your Windows system and ESP32 board cannot see each other no matter what but other devices can.

And no, it's nothing to do with the Arduino IDE core file. Not that 1.0.4 trick. Wasn't the cause. I'm using 2.0.9 now with my Wemos D1 R32 board.

THE SOLUTION IS TO MOVE THE ESP32 BOARD AND BLUETOOTH RADIO VERY CLOSE TO EACH OTHER LIKE IN MY VIDEO.

Once detected and paired, the board and Bluetooth radio device can be moved further apart.

Have tried running it with my coffee roasting software a few times. Rock solid connectivity so far even after one hour.
