I'm trying to use dronekit-python and am currently setting up SITL on windows, following the instrcution as below:
I've installed MAVProxy and Cygwin, downloaded all the files and have made them without any errors. But when I started MAVProxy and trid to move on, I got a problem with this step in the instruction:
"Configure the vehicle by loading some standard/test parameters into the MAVProxy command prompt:
param load ..\Tools\autotest\copter_params.parm"
The command prompt of MAVProxy reported an error : "failed to open file '../Toolsautotestcopter_params.parm' ".
Then if I try to move on to the next step, which is "Change to GUIDED mode, arm the throttle, and then takeoff", the copter won't take off due to "RC not calibrated".
I've tried removing all the files and started over, but same problem occured.
Has anyone seen this problem before? Could anyone help me out here? I'm not good with cygwin, and I couldn't identify the problem
Thanks A LOT!
I had the same issue. Fix by using forward slashes "/" in the command.
param load ../Tools/autotest/copter_params.parm
Thx for replying. Will try that later. Pretty sure it would solve my problem! I was so silly didn't even check the path LOL
Just checking the obvious but with the error:
reported an error : "failed to open file '../Toolsautotestcopter_params.parm' ".
It looks like you didn't add the '\' to the path and it was looking for the ../Toolsautotestcopter_params.parm file in the current directory. Ensure you are actually typing the forward slash.
You also, once running, need to set ARMING_CHECK TO 0 to avoid the RC calibration warning..
Thanks for replying!
I do use the correct sim_vehicle.sh script every time, and I've tried setting ARMING_CHECK to 0. It worked! Thanks a LOT!
But the params loading still fails. Could you please be more specific about the ' -w ' ? I'm sorry I don't really understand.
Again, thanks for your great help!
sim_vehicle.sh -w --out=10.0.1.17:14550
That just resets the EEPROM to defaults on start, you only need to do it once, next run would be
if you want you can add locations to Tools/autotest/locations.txt and start in your location
sim_vehicle.sh -L GLEN --out=10.0.1.17:14550
where i added the line
The last two params are start alt in metres and heading in degrees
Hi Bill Sorry to bother you again, but I've got a new simple problem. I'm actually kinda new to this world of MAVProxy, Python and dronekit. My MAVProxy has not yet been compiled and copied into my Python directory, and I have two questions here:
i. The tutorial says that I should start MAVProxy by entering some command line like 'mavproxy.py', but I do not know where to enter it. Do I enter it in python shell?
ii. The tutorial also says that I have to install something, with at first a command line like 'cd path\'. Again I'm confused where should I enter this line, in the shell or IDLE? They both seem to deny the cd command.
I'm sorry if these questions is to lousy for u to answer, I just got started with these and a lot of new stuff puzzles me. Please help me if you have some time free, I kinda got stuck here lol.
Thanks for replying again!
I've went through your instructions, but the MAVProxy still fails to open the .parm file.
But there seems not to be any problem, and I don't wanna bother you any further.
Anyway thanks again! Great Help!
