So I want to communicate between two arduino uno microcontrollers using two hc-05 bluetooth modules.
I know that one device has to be master and another should be slave.
By default hc-05 is in slave mode. I can change the mode of one module to master using AT commands.
My question is that in order to pair how do I send the Pass key to the other module using AT commands?
There is AT command to pair with a specific bluetooth device by mentioning its address but then I couldnt figure a way to send the Pass key.
At the end I just want to pair these two bluetooth modules and communicate between them.
