Hi Patrick,
what specs?

Do you mean telemetry protocol for Hitec in general or only for the vario?

I made some reverse engeneering of the transfer protocol.
The output from the spectra module is comparable with the description which you can find for the DIY sensorstation in the web.

The advanced sensorstation sends a third bytearray which contains the new sensordata e.g. airpressure, variometer and the 4 servocurrent values.
The variometer sends 2 words (16Bit). You have to calculate yourself height and if you want generate a variotone. The values seems tio be raw pressure values.
We have already discussed in this thread the protocol specs for the adv. sensor station.

RC Telemetry Released


It is a little tardy, but I went ahead and released my app to Google Play. Feel free to download it, there is a replay of a stored flight in there.

Many thanks to SWinn for all the help.
