I bought two RN42-XV Bluetooth Modules and I was wondering if it was possible to have them communicate with each other. I have them connected each one to a micro controller, i set one blue tooth as the master and one Bluetooth as the slave. i set the baudrate of one to 9600 but when i try to set the other one (master) to 9600 i get an error message. i factory reset the settings and tried to again but i still get an error message

Are you planning on telling us what this mysterious error message is?

“error message” … Do we have a need-to-know?
