Hi Mike,
Thanks for the link. I have that information and all the information I found on the web seems to be based on it. There are some Youtube videos showing AT commands being used and the device being used in the transmit mode but that was with a mobile phone so the pairing would have been initiated from the mobile phone. One thing that does not work as expected is the Aux_det input. (Pin 18) When that is held low (The state to select the Aux inputs) the device does not enter pairing modes with the two LEDs flashing. (The red LED is permanently on.) I have a suspicion that the device is being shipped with different versions of the firmware. I have not seen any information about different firmware versions or how to reload firmware.
Les.
