I have recently bought two HC-05 to be able to communicate between two arduino boards. I need to switch one to master mode but after watching tons of videos and tutorials, I just can't get it right !
I get how to enable the AT mode and I know I have to write AT+ROLE=1 to put switch it to master mode but I don't know where I am supposed to write it. I mean am I supposed to write it in the serial monitor of Arduino ? And if so how do I program it ?
For info, I am using an AT mega 2560 and I have a PC.
Thanks for your attention and for your help I hope !
