its more of a deficiency found in your "troubleshooting guide" to connections re Android and Bluetooth,for Bluesmart charger IP22 and smart monitor 712. It doesnt say how to best connect, I was able to connect only after resetting the PIN, nothing else allowed connection, I only read elsewhere that you must insert the PUK code, then the PIN resets to default.Only then you will obtain a connection. I dont believe your instruction clearly tells you this. I was going in circles until I did this. Thanks,
