APM Planner 2.0.25rc1 no parameter received

I am not receiving parameters from my autopilot ardupilot 3.6-dev.

The parameters bar shows 0% and 0/?

QGC can read the parameters successfully though. tried with APM Planner 2.0.18 has the same problem.

Any ideas?

I can’t reproduce your issue - just connected to a new build arduCopter 3.6-dev SITL with the current master of APM Planner. All parameters were fetched without any problem. System: Kubuntu 16.04; Qt 5.6.2

I have the same problem, not getting flight controller parameters/logs/live flight data, nothing…

  • Pixfalcon
  • Arducopter 3.5.2
  • Ubuntu 16.04.3 (gnome)
  • APM Planner 2.0.24

APM planner was working fine, QGC still works. I presume a linux update has messed with something - I’ve also removed and reinstalled APM Planner and run the “remove modemmanager” command again.
I’ve also deleted the connection and rebooted in various combinations, no change.
QGC tells me the connection is already in use if I try to use both QGC and APM Planner at the same time (by accident).

I’ve pasted in some sections of the APM Planner log. Note that when this problem exists tlogs are not created, only 25 or 50 bytes.

Not sure if it will help, but maybe try installing a newer build:

https://discuss.ardupilot.org/t/error-opening-logs/21212

I updated to 2.0.25 and still the same issue exists - no working connection, no live flight data, no logs, no parameters.

I noticed that the only modemmanager component installed is: libmm-glib0
If I select to remove it, almost everything else (desktop and most packages) is selected to be removed too, so I havent tried to remove this yet.

@xfacta Using nearly the same configuration I cannot reproduce your issue. All the same but I am using a PixHawk.
Are you (your user) in the “dialout” group?

Thanks for checking Arne. I checked the dialout group membership, it was OK.
I think I’ll rebuild the laptop and start fresh since I couldnt see any specific errors in system logs either.

I thought it was an APM Planner issue because QGC still works fine, and APM Planner was working well and just stopped a few days ago.
Thanks to anyone else that tried to help, or even read the posts and pondered the issues.

Before you rebuild your computer, open Nautilus and press Ctl-H to show the hidden files. Go to .config and find the ardupilot folder. Either delete the APM Planner.ini you’ll find in there, or rename it APM Planner.ini.old

Log out to make sure all processes related to APM Planner are stopped. Log back in. Fire up APM Planner2 and try it again.

I just tried that Chris, Thanks. It didn’t help though, I still get a connection for about a second or less then “Link lost…”

I’d already removed APM Planner and dependencies, removed/reinstalled everything else I could think of, deleted all related APM Planner directories, removed and re-added myself to the dialout group, rebooted, reinstalled APM Planner and dependencies … (the list goes on)

I tried APM Planner on a similar Ubuntu install on a virtualbox VM, passed through the USB/Serial device and it all works perfectly. I didn’t test firmware updating though.

I’ll keep working on it and update here. I’d prefer not to rebuild if I can get away with finding and fixing the underlying issue.

Try running command ldd on the APM binary. If you could do that for your Ubuntu install so we can compare, that would be cool too.

Here’s ouput from running ldd on Ubuntu:

I ran the ldd, at first glance everything is there but the 0x00007fef… numbers on yours are 0x00007fa8… on mine.
I’m guessing that indicates some sort of file versions, and my system has updated to something that’s not working with APM Planner

Thanks. The number is the memory location the library was loaded, so no big deal there. I guess it is a little interesting that libQt5Script.so.5 was loaded on yours and not mine, but probably OK.
What is the output from this command, ls -la /usr/lib/x86_64-linux-gnu/libQt*

Hopefully you will see something like this:

I tried that, saved your output to a file and my output to a file and did a “diff”. I couldn’t see any great differences apart from all your “5.5.1” versions are “5.7.1” in mine - that is because I just updated ubuntu from 16.04 to 17.04 to match my VM where APMPlanner does work - and it didn’t make APMPlanner work…
So currently I’m using QGC for all modifications, calibrations, downloading logs, then switching over to APMPlanner just to read the logs and graph them.

I just tried installing Mission Planner, it seems to run OK but I have the same issue - no connection to the PX4.
QGC still working OK.

It’s got to be a permissions or file version somewhere…

Hmm…maybe install Qt 5.5.1 and see what that does?

Make sure 5.5.1 is found (on the path) before 5.7.1.

I’ve been trying periodically to get this fixed without rebuilding the laptop (and that’s a whole other story…)

I thought I had it fixed today when I’d uninstalled everything qt5* and libqt* that I could without breaking the system, and a few things like mumble, vlc and openshot got uninstalled because of dependencies. Also there were a couple of different nvidia packages installed, got rid of those! Intel video will work fine for now.
I reinstalled APM Planner and dependencies.

I thought I had success as I was able to plug in the Pixfalcon to USB, start up APM Planner and it connected and stayed connected - usually it connects for a second then the heartbeat is lost. But alas, I couldn’t reproduce this behaviour. It’s gone back to not connecting for more than a second.
I still cant see anything special in system logs or APM Planner/mavlink logs that I haven’t already posted earlier.

I downloaded qt5.5.1 (as per above) and ran the installer, everything goes into to /opt but I’m not sure if any lib files were meant to go into /usr/lib/ or how to get them there.

I’ll keep trying, since I probably wont be able to easily rebuild this laptop,

There is a Vagrantfile which allows you to bring up a virtual nachine to
build APM Planner on.

There’s a PR which contains fixes to the Vagrantfile here:

(I should have made a separate PR for the Vagrantfile fixes!)
