Re: [Paparazzi-devel] Multi tiered telemetry solution

[Tilman Baumann]

I must have fallen on my head today.
Can someone point me to the code that runs the serial telemetry link in 
the ground segment?
I suppose there is a programme that parses that and lifts it into ivy?

This is, where I would think I would have to attack the problem...
