GCS connection problems

[nishant-raman]

Upon running FlyNetSim.py, and hitting Connect on the Ground Control Station window, the XTerm terminal remains displaying "Waiting for connection...". The GCS never manages to connect and proceed to activate the ARM button.

Following is what the terminal displays:

[MAIN] Starting the network simulator: xterm -T Network_Simulator -e 'cd ~/FlyNetSim/NetSim/ns-allinone-3.27/ns-3.27 && ./waf --run="uav-net-sim"'

It looks like the ns-3 is not working correctly. I have added a script "FlyNetSim_direct_no_ns3.py" that directly connects GCS and UAV bypassing ns-3. You can try running that. If that works fine, check your ns-3 installation. Also while running, do run with "-v 3" to print with verbose mode; the number 3 indicates that it prints logs from UAV, GCS and ns-3 all three of them.

Hi,
One suggestion of to configure ns3 properly before trying out the UAV simulations. You may wish to run some simple examples in ns3 prior to the UAV simulation. Please check and suggest if this fixes your issue. Please comment if you need any further help. Thanks.
