I apologize for writing in english, but I don't speak german. First of all I'd like to give congratulations to the authors of this amaizing project. I belong to the FPV spanish community "aeromodelismovirtual.com", from where we are following this project
enthusiastically since some months ago. Some of the users who began building are already enjoying their antenna trackers based on yours, the most of them are using direct GPS Telemetry protocol, and now some of us are testing the FrSky protocol.
Regarding FrSky Telemetry, we are experiencing some issues. In my case, I installed a frsky DR4-II Rx reciever on a mini multicopter equipped with a GPS onboard, and the telemetry over softwareserial provided by cleanflight (NAZE32) is injected to the DR4-II Rx serial port.
At the ground station I use the Turnigy 9x RC transmitter with a FrSky DJT tx module, from which the telemetry stream is extracted throughout a bluetooth module. The stream is sent to the antenna tracker which is equipped this another bluetooth module, and the blue led of the Crius SE flight controller is continuously blinking, and no data is shown on the LCD display. It seems like if the crius se couldn't decode any frame from the telemtery protocol.
I have verified with the android app FrSky Dashboard that everything works fine, and It display the GPS position, voltage, altitude, etc... from the FrSky telemetry stream. What do you think that could be happening? Is it right extracting the FrSky telemetry directly from the DJT module of the Turnigy 9x transmitter, or must I use a specific device for a previous decodification of the telemetry packets before sending them to the antenna tracker? Thanks so much.
