I've been having an ongoing issue with it disconnecting, some time I could see breaks in the blue signal display for the present day but still working but some times it just disconnected and I had been pressing reset to get it going again...some times it would work with no problems for days on end.
Recently it was happening regularly - tried all sorts of fixes - removing and then reinstalling the app - tech support told me to ping it ? and make sure my firmware was up to date....nothing was fixing it. Finally today I removed it to make it easier to press the reset button while fault finding and had it plugged into my computer usb supply and would you believe it it worked perfectly, so reinstalled it outside and the same fault happened again. This has led me to suspect the usb power supply that I have used which was an old Garmin usb supply for my bike computer...i think. So have removed it again and have it next to me here powered by my computer usb and it is working perfectly....so it was the USB power supply - when I first installed it I tried powering it with a cheap Chinese usb supply but it would not work at all with that.
