I am re-posting also here in the telemetry forum after writing it in the radio forum http://rcmodelreviews.com/forum/viewtopic.php?f=6&t=279
I received my new Aurora 9 yesterday.
I also ordered HPP-22 device for connecting radio to pc and also the HTS-SS Sensor Station, but these devices are currently unavailable and will have to wait.
I am excited about its telemetry features, and I am planning to study the protocol used between the sensors and the receiver. I think it could be an I2C protocol.
Will definitely try to find some more information.
The basic idea would be to decode the protocol so to add my own sensors on the plane, and to send to the pilot the collected data via the receiver data port thru the downlink channel.
On the piloting side, my idea is to build a small datalogging interface device to be used at fly field, to be connected to the data port of the spectra AFHSS module, so to log telemetry data to flash memory.
The flash memory could then be read on the pc.
I think that such a project could be very useful for Hitec Aurora9 users, and eventually for other telemetry capable radio systems.
What do you think?
Anyone interested to do some coordinated hacking?
I will also post updates on my blog: http://marco.guardigli.it/2010/09/hitec-aurora9.html
