Hmmm, a lot is missing in the wiki :-(
You have to run the session "Flight address@hidden" or "Flight 
address@hidden". If your board has been flashed with the 
funjet1.xml airframe configuration, then you want the Maxstream session 
(because of the -DDOWNLINK_TRANSPORT=XBeeTransport flag). The speed is 
9600 in this airborne configuration so:
 - run the Flight address@hidden session
- stop the Data Link agent, replace 57600 by 9600 and restart it
- you should get information on the GCS (the battery level for example)
- from the Tools menu in Paparazzi Center, run a Messages agent to see 
all the telemetry messages
- Save your session for later use (from the Sessions menu)

Hmm, the wiki is incomplete and out of date :-)
