Does anybody has a lead to the problem of driver compatibility of, here2 GPS with arducopter latest code ?
the time values from GPS aren't correct
"GPS1 configuration checks failing"
i have here+ also, but the problem is still there

If I wanted to create a PR for the Plane complete parameter list, should that be a bug report or just on its own from a branch?
Henry Wurzburg
@Hwurzburg
@TunaLobster what is the issue?
Henry Wurzburg
@Hwurzburg
you can do either, if its a bug you think needs fixing, post a bug report issue....and if you have a proposed fix, issue a PR off a branch you have made from the current master branch and fixed...if its an enhancement you do either (create an issue for requested enhancement) or both....if you have a PR, you might want to test it in SITL yourself before posting...

@TunaLobster
@Hwurzburg It's just documentation stuff. It's a change to the AP code since that part of the wiki is generated from the comments. No changes to what the autopilot is doing. I'm reading through it as a way to learn capabilities and catching small things as I go.

Good news @peterbarker I have found a way to reduce the CMSIS DSP library flash usage by 70k. The majority of the size is in the FFT twiddle tables. If you only select the ones you want the linked size goes down considerably.

Can somebody help me with the position controller? I was going through the loiter code and I figured out that in loiter pilot's inputs are considered as accelerations, then these accelerations are integrated to be used as desired velocities and finally these velocities are integrated to be used as position targets. So far so good, I don't understand the reason of feeding-forward the desired velocities and accelerations directly into the the calculated targets ( line 997 in AC_PosControl.cpp ) and ( line 1053 in AC_PosControl.cpp ).

@rmackay9 @tridge What version of Rover has (or will have) the fix for param reset on boot....I can't seem to find the commit that addressed that....It happened to me for the first time today on my boat...came home and attached to MP only to find that I now had a Ground Rover instead of a boat....using stable Rover 3.5.1

I have been hearing about drone attack in the news from terrorist overseas and it's not cool. I would love to write a module for ardupilot that deams certain areas no fly zone to help prevent this. If you guys are ok with that I would contribute 100% to prevent further attacks!

@Hwurzburg, I've also seen the param reset problem but only once and it was using Copter latest (i.e. not a stable release). I was not aware that we have a bug like that in our stable releases...
@BabakAkbari, re the feedforwards in Loiter, I suspect this is because it adds a much faster response. So the vehicle leans much like it does in AltHold mode.

How can I know when the copter is ready to take off? What mavlink message to watch for?

Hi all, what's the process for getting upstream mavlink changes into the ArduPilot fork? ( mavlink/mavlink#1215 )

@arjunkapoor763
can some help me with getting system time function
like which function needs to be called
hal.util->get_hw_rtc()/1000
will this returns the gps time in UTC in seconds?

@DorkMatter
Hi all, I'm trying to setup ArduPlane with gazebo using the ardupilot_gazebo plugin, however when launching the zephyr_delta_wing I get an error from Gazebo saying that it can't find the imu_sensor and it aborts loading the plugin. I have two colleagues who are experiencing the same issue. I've tried manually setting the plugin path to point to the gazebo imu plugin, but it's still throwing the error. The error persists across Gazebo versions (at least version 9 and 7).

@DorkMatter
I should clairty that I'm using the zephyr_delta_wing model from @SwiftGust

@OXINARF
@m-sasha What do you think ready to take off is? There is no such exact state in ArduPilot.
@naruto-raj No and no
@IamPete1 You have to open a PR against our fork. As @khancyr said, @amilcarlucas usually ports stuff periodically
@arjunkapoor763 You asked two different things, do you want system time or UTC time?
Peter Hall
@IamPete1
@OXINARF @khancyr Thanks, I can do a PR to rebase ardupilots common messages on mavlinks or would it be better to just PR my change?
Francisco Ferreira
@OXINARF
@IamPete1 I'm not exactly sure what you mean by rebase (it can mean multiple things). What @amilcarlucas usually does is port all commits that have changed common. You can just PR your change, it's not a problem.
Peter Hall
@IamPete1
great, Thanks!
Peter Hall
@IamPete1
PR in, its here if anyone wants to take a look ArduPilot/mavlink#108
Peter Barker
@peterbarker
@m-sasha If you're asking, "when can I arm the vehicle", that's slightly easier - check the autotest suite's wait_ready_to_arm function. It's not great, but seems to work (except Rover seems to have changed behaviour....)

is there a particular reason why AC_PID_2D doesn't have a kD() getter like it does for P and I? AC_PID.h does have all 3 getters. https://github.com/ArduPilot/ardupilot/blob/1a7284ca73dc06ab6a311f86c7922e21769d1ef4/libraries/AC_PID/AC_PID_2D.h#L49

@andyp1per I might have found an answer. Mavproxy's GUI client in Windows shows what tasks are causing overruns if sched_debug = 3https://imgur.com/TVOLdyi

@OXINARF i want UTC time

@arjunkapoor763 Anything wrong with AP_RTC?
arjunkapoor763
@arjunkapoor763
no no i just checked it is working absolutely fine @peterbarker

@AndKe
How do you compile SiK radio recently? - the issue is described in ArduPilot/SiK#53
I think there should be a fix to that, some compiler-option that make it work again.

@AndKe
@rmackay9 ArduCopter have been at the North Pole (geographic north pole) ! - this is far more exclusive than most other spots on earth. EKF handled the proximity (<500km) to magnetic north just fine. Look at the fun icing near prop hub on one of the many places we flew:

And another place (different conditions):
20190825_235240.jpg
In any case: this is a fun-fact to add to ArduCopter history :)
Francisco Ferreira
@OXINARF
@AndKe can you make a blog post about it? That would be a pretty great story to have

Are you guys cross referring the Lidar distance with baro?
While on the ground I get several hits at a distance >80 meters. Also are you averaging the results from rangefinders?
