I have an avid interest in the Arduino board and have sucessfully programmed it for may apps.
Now I would like to use Bluetooth and have purchased the popular JY-MCU module.
However I cannot get this to reliably pair with my iMac, most of the time it just reports Pairing Failed. Just a few time it acheives connected, but very rarely.
Any inputs about how to solve this one?
