Re: [Paparazzi-devel] Ground Station Communication Stuff

[Pascal Brisset]

Hi,

the datalink_time variable counts the number of seconds since the last 
message received from the groundstation (dalalink.c:58, main_ap.c:414). 
So you can do a test on this variable in your flight plan and be 
derouted in another block. There is an example in basic.xml:

     <exception cond="datalink_time > 22" deroute="Standby"/>

Note that the link agent sends a PING message to each aircraft every 5s
