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.

Wireless telemetry for spectra modules and A9 has arrived!


have a radio A9

you already have the wifi system for android compatible with telemetry hitec?

gostarai of adiquirir one

thank you

Spectra Module Interface to Bluetooth

Hey fellows,

I have a blog post that shows how I made the Spectra Interface from a Teensy and Bluetooth module. Here it is:

I will be updating it soon based on some information I received and tested out. I will be adding external pull up resistors to the I2C lines, using the internal pull ups on the AVR cause problems and I am not going to use them anymore.
