If the 2 outside lights on your Ray are both red then it's a signal that the GOFAR device is NOT connected to the GOFAR app.

Opening the app or toggling bluetooth off and on again will usually fix this.  Failing that following the steps in GOFAR is not connecting to my phone.

The Ray will still work normally during your trip, changing colour as you accelerate and brake.

The unit will still score and track your trip, you just won't get a map for the trip, as it wasn't connected to your phone.

As soon as GOFAR reconnects to your phone, the 2 side lights will go blue again.
