Hello,

First if this is posted in the wrong place feel free to redirect me to a better forum.

I've been following this tutorial.  I've got a FTDI cable connected as described (without the +5v connected) and that seems to be working.  I've set the baud rate as described.  When I get to the section to enter the command "mavproxy.py --master=/dev/ttyUSB0 --baudrate 1500000 --aircraft MyCopter" here is what is shown through the terminal:

odroid@odroid:~$ mavproxy.py --master=/dev/ttyUSB0 --baudrate 1500000 --aircraft MyCopter

Connect /dev/ttyUSB0 source_system=255

no script MyCopter/mavinit.scr

Could it be that I missed something while installing the packages listed in the tutorial?

Any help would be greatly appreciated!

Hi Loren, it seems that initially it works well (otherwise you wouldn't get parameters, heartbeat, and mode). Are you running Ubuntu 14.04?

Yes I believe so

It's failing to resolve the DNS name to get the terrain data.

what version of MAVProxy are you using and ArduPilot?

mavproxy --version

I connected the Odroid to a network that had internet connectivity today and it worked.  Do I need to have access to the internet for my Odroid to run mavproxy properly?  Or did I misunderstand the DNS issue?

MAV Proxy should fail gracefully, but it doesn't. (bug)Copter doesn't use terrain following yet.

Try making sure TERRAIN_ENABLE is set to 0 in the FW so it does't make a request for the data. http://copter.ardupilot.com/wiki/arducopter-parameters/#terrain_dat...

And feel a bug against MAV Proxy
