Drove for an hour or so, the device is still working, stopped at the store. Car is turned off, USB is still activated on the phone, went back turned on the car, opened the app, the app is now connected, calibrating message.
Drove for 5 min, and still calibrating, I forced the app to close and reopened the app. and the devices are connected and displaying.
@Julieta do you think this is a glitch in the software, as this happen to me more than once, or is it normal behavior, once you turn the car off you need to start a fresh, the app wont keep working in the background and update it self when the device is powered back on.
I will keep an eye on that and will keep you posted and updated,
