Hi Roman,

you started a session, probably "Flight address@hidden".
As you can see the link is looking for the modem under /dev/paparazzi/xbee
And your modem is not available under that device. You can make your
specific modem available under that name by creating an appropriate
udev rule if you want.
Also you started the link with "-transport xbee", but I guess you use
transparent mode...

So just make a new session for yourself with the appropriate
parameters, I'm guessing
.../paparazzi3/sw/ground_segment/tmtc/link  -d /dev/ttyUSB -s 57600

Cheers, Felix
