Hello,

I'm trying to connect to the UA-651BLE blood pressure monitor, I am able to successfully scan for the device, and issue a connect from the scan call back. After connect, when a services discovery is done, the BPM immediately turns off with E 10 as error code. The same happens on your test app as well. Do you know why? Below is the log snippet. I am using a Moto G4 running Android 7.0
