TSA9840B (TinySine) Mono/Stereo Programming Issue

I have a TSA9840B (TWS/Apt-X) module I'm wanting to change from stereo to mono. I keep getting an error each time I try to connect. I've followed the instructions on the TinySine website but no luck. I keep getting a Read Config Error (unable to read product ID) has anyone been had this same error? If so, how did you resolve it?
