Cube black in Kore board fw 4.0.3 resets param

Already happened 3-4 times. cube black in Kore board fw 4.0.3 resets all params to default.

Running latest 4.0.3 stable and updated bootloader.

Everything reset to default, even missed frame type, EVERYTHING to default.

Is there any solution to this? It is very very annoying and dangerous problem.

I just updated bootloader using mission planner but i am on 4.0.3, should i update to 4.0.4 and update bootloader again?

How can we check we have latest bootloader installed?

Pixhawk 4 Mini + R1 clone receiver (Yaapu)

Following on from my previous post, can anyone tell me if I can connect directly together a Pixhawk 4 Mini and a R1 clone receiver to enable Yaapu telemetry over S.Port. The Pixhawk Mini is 3.3V on the telemetry pins and the R1 looks to be the same or is it 5v TTL.? and would need a MAX232.
Obviously I still need a the diode to ‘mix’ the two TX and RX on the telemetry to the single pin S.port.

Mower / Large vehicle compass calibration and selection

Hey all, I’ve been following a lot of the threads and youtube videos from @ktrussell and @bitdog etc and it has been a big help in getting my ZTR mower equipped with flight controller and servos. Thanks for all the posts.

My machine is driving great now in the yard by RC and I’m working on nav today. I think I’ll be able to get the U9P GPS RTK setup working today, but I can’t seem to get my external compass calibrated. I picked up the LIS3MDL board and whatever I do the calibration fails (usually “bad radius”).

Is there a better sensor I ought to be using? Are people using Large Vehicle MagCal with good success? I’ve been using QGroundControl on a Mac and I saw this was NYI (https://github.com/mavlink/qgroundcontrol/issues/8142), but maybe I need to find a Windows box for Mission Planner.

Would it be possible to kick off Large Vehicle MagCal using the mavlink console even without UI support?

Latest Windows 10 does not recognise device. (Pixhawk 2.1 Cube Orange)

Since the latest Windows 10 version 1909 update I keep getting a message off windows saying, “the device malfunctioned and the device was not recognised by windows”.
I have tried putting windows into test mode , tried turning off windows signing and other things to name a few without any success at all. It seems windows is going all out blocking unsigned drivers.
Is there anybody out there who have been successful in overcoming this problem.
I’ve spent hours trying to connect to the Cube. Even radio telemetry cannot connect now.
I beginning to hate Windows with a passion.

So my next effort is to get video to Qgroundcontrol if that is even an option? So my question can Qgroundcontrol be set up to except video from drone? If so where does one go for such I am not seeing anything anywhere.

I do see Camera under vehicle setup but not seeing anything for streaming video, all options there are re gimbal?

BTW anyone in the Dallas or North of Dallas area real good with Qgroundcontrol? Would love to find a willing tutor, lol.

GPS says NO-GPS

Last week everything was fine. Today I connected a HERE Flow to the CanBus and put on some Flow params. I am not able to get any SAT and it says GPS: No GPS.

GPS is a type 880 with Compass. GPS has blue LED on, flashing, with a brief red flash also.

So I unplugged the CanBus and that didn’t fix it.

So I reloaded a backup of the Parem file from last week, that didn’t fix it. It gets no satellites. now.

This is a Pixhawk 1 (9) from a 3D Robotics Iris. I am running the latest Arducopter 4.0.3.

Any ideas?

Visual Studio Development of MP

Hi All,

I’ve been developing in visual studio, compiling and changing software and such. And I have been running all of my git commands for pushing and committing and such in linux. (I have the folder where both visual studio and linux access it linked on my windows host)

Whenever I compile and run my debug version of MP on the windows host, doing a git status on the linux vm where my repo lives shows a whole bunch of files changed.

Is this simply windows doing something to the files that git picks up on? Is there a simple way to avoid seeing so many changes pop up when I havent changed those files?

Are all of these changes normal?

Any help would be great!

Hi guys!

I trying delete and creation a new mission during the auto flight mode.
I use this metods:
mission.stop();
mission.clear();
mission.start_or_resume();

And then I create a new command with the location specified as follow:
//First wp
cmd.id = MAV_CMD_NAV_WAYPOINT;
cmd.p1 = 0;
cmd.content.location = inertial_nav.get_position();
cmd.content.location.offset(x, y);
cmd.index = 0;
cmd.create = true;
copter.wp_nav->set_wp_destination(cmd.content.location);
mission.add_cmd(cmd);

       //Second wp
        next_wp.id = MAV_CMD_NAV_LAND;
        next_wp.p1 = 0;
        next_wp.content.location = location;
        next_wp.index = 4;
        copter.wp_nav->set_wp_destination(location);
        mission.add_cmd(next_wp);

But the problem is that it skips the first created wp and goes straight to the second. How do I make him follow both wp? I try change the index equal 0 in both.

Thanks!

Shaking up and down

I have an ARWing and a servo was damaged in a crash where the gear stripped.

I replaced that one cheap analog servo with a digital metal gear servo. I knew I should probably replace them both, but didn’t because the wire was too short and I had to solder a bunch to replace the first one. I am using Ardupilot and it was set to auto-trim, so I figured it would just adjust quickly and learn the new settings.

I flew it and it took off, then started shaking badly. It was strange in that it didn’t spin or anything, but was shaking up and down. I could see the wings “flapping” like the elevons (perhaps both of them since it was flying straight and level) were going back and force in a quick cycle.

Is this the expected result of having two types of servos? Or could something else have caused it?

Here is the log: https://www.dropbox.com/s/zsb78yl98bvjasq/2020-07-04%2012-50-45.log?dl=0

Moter spin after 50%

@Yasu wrote:

After setting the stabilizer mode and arming, gradually increase the throttle from 0% to increase the motor speed and take off. However, after putting the arm in Reuters mode and turning the throttle,
Take off when the rotation speed does not increase even if gradually raised from 0% and becomes 50% or more.

Is it possible to take off if the rotation speed does not increase even if the throttle is gradually increased from 0% after the arm is exercised even in the stabilizer mode and it reaches 50% or more?

Multi Radio Telemetry Receiver

@eM.Farih wrote:

Dear all,

I want to build a medium UAV that will travel across 200km. I have seen RFD900 could achieve 40km. Is there any solution like applying a repeater to the telemetry in each overlap section (eg in every 40km) with two GCS (one base GCS at the take off and the other one at landing)? or is there any solution to not loss the telemetry connection?

Thank you
