[Paparazzi-devel] telemetry not working

[Adrien Fallou]

Hi everybody,

   I've been trying to get paparazzi working for some weeks now. I'm using a PPZUAV tiny 2.11 board with FTDI utility board, with Xbee pro Znet 2.5 upgraded to Xbee pro ZB through X-CTU, and Paparazzi running on Ubuntu Lucid Lynx (10.04)

    I have flashed both parts of the modem using X-CTU, set the baud rate to 9600, and checked that the airframe is correctly configured. As I wanted to be sure of that, I also tried with the funjet_example airframe, which matches my hardware, but still have the same issue.

    Using the X-CTU terminal, I have checked that the two parts of the modem communicate : I do receive the messages I'm sending through one of them with the other one.

    

     My problem is that when running paparazzi, I get a blank GCS, and no messages, but I don't get any error. I have read that this could be because it is waiting for a telemetry signal, but I don't understand why it's not getting any. As I don't have any blinking LED on any part of the modem, it seems that paparazzi is not able to communicate with it. Do you have any idea why ?

   Thanks for your answers,

Adrien
