I am using two HC-05 Bluetooth modules with two Arduino Nano boards
I have the blue tooth pairing OK
the code I have wrote seems to work OK too
what happens when I put power to the project a LED comes on the master controller and when I disconnect the slave blue tooth the LED go's off this is what should happen
The two controller are connected to the same computer for power
the problem is when I change to a different power supply the LED comes on but when I disconnect the slave the LED stays on
when I plug the Nano into the computer they seem to pair with them self's as the red LED on the board flashes together
can someone help me please
can you post the circuit wiring and the code?
