So I have the Status -1 today when trying to connect with my main Android.
Made sure to kill the Mooshimeter program, cleared the Wireless Settings, sill no connection.
Tried to scan for the Mooshimeter BT, did not see it on the meter.
Turned off the BT on my phone that was on my belt.
Finally decided to restarted the tablet and instant connection.
Not sure what is going on, something maybe with the BLE stack in the tablet, I use a number of different standard (non BLE) Bluetooth wireless OBDII interfaces on this tablet an never have a problem with these, this is the only BLE device I think I connect to so far with this tablet.
