Navio2 led color meaning

I see this no where in the documents and I am tired of not being able to deduce whats going on without a ground control station. At times I dont feel like using my laptop and tower is very limited as far as I am concerned. If there was a way I could calibrate everything on the fly from an android device and read mavlink warnings etc that would be great.

As a side note. I have a turnigy 9xr is anyone aware of how read telemetry data from navio2?
