Hi everybody,

I just begin to manipulate Paparazzi hardware and software. 

For now : 

- I succeed in working with flight plan simulation

- I succeed in uploading software into my Lisa M AP 

- I succeed into programming my Xbee modules with XCTU (windows) with the PPZUAV FDTI utility board. 

BUT : 

when I plug the FTDI board with xbee module (coordinator) by USB on my ubuntu computer, I have the following error when starting a session : 

Failure("Error opening modem serial device : fd < 0 (/dev/ttyUSB0) ») : 

RUN '/home/nicolas/paparazzi/sw/ground_segment/tmtc/link -d /dev/ttyUSB0 -transport xbee -s 57600'

Failure("Error opening modem serial device : fd < 0 (/dev/ttyUSB0)")

Broadcasting on network 127.255.255.255, port 2010

 Read Socket : Connection reset by peer

FAILED '/home/nicolas/paparazzi/sw/ground_segment/tmtc/link' with code 1

I have checked with dmesg that /dev/ttyUSB0 seems to be the good place for the board.

I have added the current user  to the modems group as explained in the FAQ (http://wiki.paparazziuav.org/wiki/FAQ). 

I made the xbee module set as coordinator, with baud rate set to 57000 

My Xbee is a 868 LP 80 K modem. 

On the PPZUAV FTDI board the red led is ON. 

The green led is ON (but not flashing).

Have you any idea of my mistake, or configuration that I did not do ? Are there some drivers to install for the FTDI board, or a configuration to put into the xml files ? 

Thanks in advance

Best regards

Nicolas
