user36761: Using this as a tutorial, I've tried to connect the master Bluetooth module from my Nano to the slave module in my Mega. After following the steps in the tutorial, when I enter the command to my serial monitor:
AT+BIND=98d3,31,30690

I receive:
ERROR:(7)

After looking up the error, I only get results for ERROR:(0)
Does anyone know what the error means or how to fix it?

user36761: I found the solution.
Apparently, both of my modules were at 9600 baud rate when the optimal rate is of 38400. I had to use AT+ORGL in command mode to reset both slave and master. Afterwards I was able to connect them manually.
So apparently ERROR:(7) represents a failed connection? Just don't forget to make sure everything is exactly like the tutorial that's teaching you.
