I am building a series of devices that are interconnected with bluetooth. I use the HC-5 module for this, as a master (MODE = 1) and as a slave (MODE = 0). I have set the masters via AT commands to bind with only one specific slave. This is done by setting CMODE = 0 and entering the address of the specific slave bluetooth module in BIND. However, when I put a master and slave next to each other and turn it on, the master binds to the slave, even if it is not the specified slave. Does anyone know why this is and what I can do about it?
