I am just testing the RTK injection with a Drotek RTK system and MP 1.3.44.3
Questions:
- I can't enter a lower accuracy setting than 2 m. When I enter another value, is set back to 2m again when I switch screens
- where can I find a description of the parameters settings and status messages?
- what does "In progress: false" mean?

I'm trying to run a simple Auto Mission (3 waypoints) and when Auto is selected it doesn't throttle up. The steering moves like it's ready to head for the 1st waypoint but the vehicle doesn't move. I have good manual control of the vehicle and I see no errors in the log so I'm stumped as to why it won't start. I have a lot of experience with Missions with Copter where the mission will start by selecting Auto mode and raising the throttle. I have tried that here to no avail.
Well, as it turns out it was just the throttle chan max range was off. I was sure I calibrated the radio but in any case the vehicle starts now.

My problem:
- I cannot arm copter 3.4 in LOITER mode.
- I cannot switch to LOITER mode after take off in ALTHOLD.
My setup:
- PX2 controller with Copter 3.4.5 stable firmware.
- LIDAR Lite v2 set as range finder.
- PX4FLOW Optical Flow sensor reporting good values.
- ALTHOLD flight mode works well.
- No GPS is attached.
My symptoms:
- I get a pre-arm check error: "Need 3D Fix"
- When I switch in-flight to LOITER, I get an error message in the logs: "Subsystem:10 ErrorCode:5", which I believe is: ERROR_SUBSYSTEM_FLIGHT_MODE and ERROR_CODE_DEST_OUTSIDE_FENCE.
- There seems to be no effect when I switch to LOITER mode during flight. The copter has significant drift.
What I have tried:
- I have gone over the PX4Flow setup instructions several times and confirmed that I am getting good values from the sensor.
- I have triple-checked that my EK2_GPS_TYPE is 3 for optical flow.
- I have triple-checked that the geofence is disabled.
- Set GPS_HDOP_GOOD to a high value (9999)
- Upgraded firmware from 3.4.3 to 3.4.5.
- Confirmed that the GPS pre-arm check is disabled.
Any suggestions greatly appreciated! Thanks!

Hello all!
My name is Guilherme Sousa, I'm an Aerospace Eng. 5th year student currently working on my MS thesis in Flight Control at ENAC in Toulouse. First of all congratulations to ArduPilot on getting selected for GSoC this year. I'm opening this topic as I am interested on the improvement the flight cotrolers for the Single and Coax copters. I've been running some simulations on SITL and the singlecopter even with the presence of wind seemed to perform similarly to a quadcopter on waypoint missions. What would be the next step testing the existing controller of the singlecopter?Thanks!

In Mission Planner my drone responds accurately to increase or decrease of the trim for both sticks. However when the actual sticks are moved up and down nothing changes. The only thing that does work is the throttle which shows up how it is suppose to when it is moved up and down. Basically the right stick, the pitch and roll stick does not work but the trim still works so the reciever is working fine. I have looked at factory reset but people said to do it only if you have to. Is there anything else I can do to fix this?

Hi guys. This is my first ever post on a forum.
I have a hex running a pixhawk (with latest firmware).
I have been getting quite a few EKF Primary changed messages occurring while I'm in the air (Err.EKF_Primary-1 & Err.EKF_Primary-0 in the log) I don't know if this is normal or an indication of something sinister brewing. I can't find much info online.
A week ago I got a lot of these in a flight and seemed to partially lose control of my drone. I was also getting 'Inconsistent compass' warnings on the ground prior to the flight so assuming the two were related I re-calibrated my accelerometers & compasses.
I flew again this weekend albeit on a very windy day. The inconsistent compasses issue has gone but I still got a few 'EKF Primary changed' messages. Could wind gusts be causing these latest EKF messages?
I've attached the log file from my latest flight if anyone has a moment to look.

I have a working configuration with AC3.3.3: I can adjust the shutter min/max values for the gimbal in MP (connected on RC9) and control a nick servo on RC12 via passthrough the servo signal to RC12. Then I updated this config to AC3.4 and it doesn't work no longer. I can put in some min/max values for the trigger, but these changes have no effect on the servo. On the other hand I'm not able to get a simple servo working on any other RC-output on the servo rail in "passthrough" mode. Are there any hints or workarounds for this issue? I need this functionality in 3.4.5 immediately!

I am using Pixhawk from the chinise company Holybro.
for the external compass which is always automaticaly assigned by the pixhak as compass1 I get very high offset values:
like. x -344 y-98 z 155I changed yaw to 90° 270° and none
The large offsets do not change, only the values move to Y and x
When I want to start the copter it goes to one side and I have not the guts to give full throttle.
First time flying and I am a beginner never ever had a RC in my hand.
maybe you can advice
regards
PS:second compass has normal offset values as far as I can judge (20)

On Saturday I upgraded to AC3.4.5 and after calibrating everything again, my test flight went fine. I then tried to program a ROI mission in the latest version of Mission Planner using the Circle Mission option. The quad flew the mission circle just fine, but it never changed its orientation towards the ROI as it was circling.
According to the Wiki, since AC3.2 you only need to set the ROI once and the quad will face it through the mission,but this didn't seem to work. Am I missing something?
Any help appreciated.

I found "Example" folder in each libraries.
there was only *.pde files.
All file's format in the library folder was *.cpp
What does it mean "example"..?
is it essential for running Ardupilot firmware?

Hi Everyone.
I have developed a Simulink model for ArduCopter for tuning. i have a problem on the validation process where ArduCopter altitude mode uses stabilize mode. the problem is the quad tries to self stabilize when you give it a step input. anyone know how to disable self-stabilizing mode would be very helpful.

Hello,
My name is Ilie-Ablachim Denis and I am a student of the Faculty of Automatics and Computers Science. I hereby express my interest for the Copter Object Avoidance and also wish bring a contribution to it.
Currently, I am in the senior undergraduate year and am working on my Bachelor’s degree. I wish to approach a new field, with broad perspectives, but also with the potential of making a strong impact. This is why I chose to introduce the following concept: UAV trajectory control and image processing techniques for smart agriculture decisions.
I would like to bring my contribution to this project by including an algorithm for the AUTO mode. This is also a main object of my Bachelor’s thesis. Based on readings from Google Maps, the user should be able to mark their area of interest by choosing a number of border points. After this step, the program should run a basic algorithm to find the shortest path for data recording during the flight. Thus, I discovered I would need an avoidance algorithm for my drone and I am trying to implement something based on 2 articles of one of my teachers from university ( https://www.dropbox.com/sh/cpepa51229o8jbu/AABBJWJMWs5Jv-BUyCjfeRUea?dl=0 ). So far, I have access to 2 drones from my Faculty: a DJI F450 and a hexacopter with ArduPilot.
I would like to know more about this project and to discuss the possibility of implementing this for any drone model using ArduPilot. Also, if you have some datasets or records which I could use in my work, I would be more than grateful if you could provide them.
Thank you in advance!
Sincerely,
Denis

Hello i'm the one who uses the arudpilot and emlid navio2 hardware with RPI2.
I'm using the latest ardupilot software (2017.3.4 commit 2631bdbe64e32a9607bda642125a87f5979aafc6)
(Just in case, u need to build with 'waf --targets bin/arducopter' not 'waf --targets bin/arducopter-quad)
Actually the issue i'm trying to mention is irrelevant with the software version.Anyway, whenever i run the ardupilot software on the RPI with Navio2,
i suffred some sensor failure like barometer when the ardupilot initializing, very often.And when i initially calibrate the drone with mission planner or APM planner,
the software does not work with errors like AHRS failure, and any other error with barometer.Therefore, at that time, i really search the web, but i can't find the solution and it just worked after several tries.
Now, i think i figured out the source of error. It's the hardware-wise problem, not software.
As you see at the image below, now i make the board float a little bit with dumping ball.
I didn't have those dumping balls before, so i just made it stick to the substrate screwing it to the substrate.
I think the RPI with Navio2 leak the current to the substrate or interfered by the substrate, sticking to the substrate.
Therefore, the value of the barometer or other sensors on Navio2 does not work properly.In conclusion, i'm just writing the article wishing there would be no one suffering the same problem like me.
Because i saw some same issues here around with title "Failed to initialise ADNS3080” Problem".
I guess it's also same issue.
Thanks.

Hi
I've compiled most recent version of ArduCopter but, motor_test app does not exist.
However, if I compile 83d39 (most recent stable version), that shows motor_test app.
Does anyone knows why?

Hi,
Can somebody please help with a RTK com port connection error that I’m getting?
I’ve had RTK here+ base connected to a Windows 10 Laptop for a couple of days and it’s been working fine on com port 10. Then this morning on connecting I get this message “Error connecting”. It doesn’t see com port 10 anymore in the drop down box next to the green connect button. I haven’t made any changes to the laptop.
A few of things that I have tried:
Updated Mission Planner to latest beta, didn’t fix the error msg.
Uninstalled MP and reinstalled older version, still get the error.
Tried a 2nd RTK base on this windows 10 laptop and it produced the same error.
Change the sample rate which didn’t make any difference.
Installed U-Blox U-centre (VCP) and can connect to Here+ on com port 8 and it works fine/ can see all sats working.
Win 10 laptop has the latest drivers.
Mission Planner sees RFD900 radio modem on com port 4.
Tried it on old Win7 laptop, initially had the error but then updated Mission Planner to latest beta and now works fine.Nearly drive a man to drink!
Appreciate any help?
Thanks,
Steve

Issue details
iv'e buy a new pixracer and load Ardupilot 3.45 firmware, but i've a problem.
I set up all the sensor, soft tuning ad seam go fine.
But when i switch on for the first time and arm it for the first time, the drone fly fine, but when a rearm for the 3-4 time Qgroundcontrol tell me Arm check: gyro still setting and the drone is not stable.
If i see the gyro are not set correctly on horizon, but when i disarm ti fix yourself.
Then if switch off and switch on again the drone go fine and very stable until to the 3-4 time that i arm and disarm again i have the same problem.
I've test it with an other board and it do the same thing.
What is the problem?Version
3.45

[ ] All
[ ] AntennaTracker

So it looks like it's time for some more OBC development!
From what I can tell so far the main differences to last years event are:
- 3 separate prizes depending on level of achievement
- $25,000 for completing the mission with the highest points
- $25,000 for using type 2 autonomy (now being redefined as "no controller/user interference, but with constant comms link to controller)
- $25,000 to avoid Dynamic No Fly Zones (details yet to be disclosed)
- Manual hand launches are no longer considered autonomous (excluding them from getting type 2 prize)
- Layout of course is different, with only the first two waypoints needing to be completed in order and the inclusion of no fly zones
Still the same:
- Range and VTOL required to pickup the blood sample from the remote landing site
- Aircraft size allowances, propulsion etc
- Geofence requirements (addition of no fly zones)
- Comms required when retrieval aircraft is on the ground at remote landing site (ADS-B transponders might be introduced)
Overall it seems like the biggest change in comparison to the last one in 2016 is the emphasis on, and the extra prizes for automation. The aircraft platforms can be the same, so our last one should work fine.

Hello everyone, just made my setup for aerial mapping. I'm using pixhawk (arduplane latest fw) with dragonlink v3, and canon s100 with CHDK fw, and tuffwing shutter cable for canon. Made everything according to instruction on manuals and guides and it won't work, however with ArduCopter fw it works fine. And yes I'm noticed those warning notification on wiki page that work only on copter fw, and I'd like to be sure will it work DO_Digicam_CONTROL mission command during auto flight. Any thoughts?
