It's all really rather random. Sometimes it records trip data sometimes not. Sometimes it creates battery test results without prompting which if it's own trip data is to be believed would have been while I was driving. Sometimes it won't connect to the device at all. At the end of the day leave me wondering if the data it generates is random or can it be believed?

The app keeps disconnecting when "mobile data" is on. After turning off "mobile data" and restarting the app, the bluetooth connection works as it should.
