    The HC-05 module data suggests it can either connect to any device (CMODE=1) or connect to a fixed address (CMODE=0)

    Having used the AT+RMAAD, AT+BIND, AT+LINK commands and Set CMODE=0 the unit still seems to connect to the first device it finds after a reboot rather than the specific address I would prefer.

    I have one HC-05 configured as master and a number of units set as slaves, by setting the individual MAC address for the target I would like to be able to select which slave I am communicating with. Is this possible ? If so what am I missing ?
