Analog RSSI on Omnibus F4 Nano V6
@avi8orn8 wrote:
Is it possible to read an analog signal somehow on the Omnibus F4 Nano V6? This is the only type of RSSI my receiver will output. I have tried setting RSSI_TYPE to 1 and RSS_ANA_PIN to 103 (using the SBUS port) but this does not seem to work.

Hi Folks,
i have weird issue and i cannot solve it.
i build new platform witch is H Copter, i have FC Matek F765 witch arducopter 4.0.3 and GPS module Drotek zed f9p on board, on the ground i have second zed f9p to get RTK. like a telemetry and rc signal i use rfd900x.I done few test fly and everything was ok, but sudenly after change battery to next flight i get error “prearm: 3D fix needed”, at the same time my GPS onboard shows about 20 satellite and 0.5-0.6 HDOP.
i am fighting with that issue few days. i change firmware in FC to older, bring all settings to default - in FC and in GPS module but there are still has the same issue.
anyone know what go wrong?

Copter 3.6.10 Problem Axis YAW
@White wrote:
Hello guys.
I have drone Octa Quad. Engines - MAD 8108 170KV , ESC - T-Motor 60A FLAME HV, Propeller - 22.2x7.2, battery - 12S 16000 mAh.
The drone holds well in the YAW axis without the wind - Yaw does not rotate, it holds the drone in one place, but during gusts of wind (5-7m / s) it suddenly rotates in the YAW axis, after which it returns and it is good again. Does anyone know what it is caused by?
I put logs and parameters.

Autopilot in narrow places
@ecabanas wrote:
Hi all,
I have finished mounting my skidrover with an A2 lidar and everything looks fine.
I have parameterized the robot to try to get it to pass between one wall and another that is about 3 meters wide.
The problem I have is that the rover doesn’t work well, it goes backwards, goes forward, starts circling and ends up stopping.I have the object avoidance set up as Bendy ruler.
I’ll give you a screenshot in case you see something strange, okay? I’ve tried a thousand things and it just didn’t work right.
Thank’s all guys

DJI Battery Support

Topic: DJI Battery Support
Proposal type: Software [] , Other[]
Description: I have already integrated and using DJI battery(tested and working with Phantom3, Phantom4 and Mavic Batttery, need to test other models) along with ardupilot, that can be connected with Serial Port with ardupilot and show battery voltage and percentage currently (Can read each cell voltage too but the feature not available in ardupilot), Is there any legal issues to add that in ardupilot Master ? can I proceed with Pull request as usual?

Autopilot Landing and Takeoff
@Flash wrote:
Hello,
I am new here, please be kind.
I have been looking at building an octocopter based around a FC that will run with the Ardupilot system.
There is a couple of questions that I havn’t been able to find an answer for in the documentation for Ardupilot.For my project I need my drone to be able to fly a fully pre-programmed mission, for this the Ardupilot system seems perfect.
But, the area/distance needed to be covered is too big for the drone to handle with the battery power onboard, therefore I need to program an automated landing, then the batteries will be replaced, and the drone should then continue with the mission by executing a takeoff and then go to the next waypoint.
Is this possible?I see another solution to this, however, I am not fully aware of how to do this;
The alternative is to power the FC from its own battery (if possible), and power the ESC’s, motors etc from a seperat set of batteries. Is this possible?I have a ton of questions as this is my first big built, however have been operating drones for a decade, mainly S1000 and phantoms.
I hope there will be some friendly souls out there who willing to help me out.
Thank you in advance.

(Developers) Getting started with the MP codebase? Control messages
@Dan_Maher wrote:
Hi everyone,
I’d like to modify MP to send out controller values on a pub-sub bus called DDS. Got the source code and I am experienced, but having trouble understanding where to begin.
Looks like there’s some facility for CAN bus traffic, which is also interesting to us.
I can compile and run fine, just curious if someone could point me to this area in the code.
Best regards, and thanks,
Dan

Is there a way to detect when the plane with a parachute lands and collides onto the grounds?
@aharon.moto wrote:
Hi everyone,
Do you know if there is a way to determine the timestamp when the plane reaches to the ground when parachute is open? Is it implemented in the software now?
If no what kind of conditions would you consider to detect the ground collision event?

Cannot Connect to Mission Planner on a Windows 10 PC
@flyingw wrote:
Suddenly and randomly I cannot connect a Navio2 running ArduRover 4.0.0 to Mission Planner on a Windows 10 PC. Sometimes it connects and works perfectly. The next time I try to connect, it will not and I get this diagnostic:
I’ve:
Told windows Defender to let Mission Planner run
Allowed UDP port 14550 from any IP address to the inbound firewall rules (also to the outbound rules but I think outbound uses a different port).
What else do you think it could be?
Thanks,

Ultra Wideband (UWB) Local Positioning Systems
@SteveOsborne wrote:
There seem to be a handful of UWB systems that may be applicable for drone usage. I’m left wondering whether they are all more-or-less equivalent, or if some of these perform better than others.
My goal is to simultaneously localize up to 100 drones, all within roughly a 50 x 50 m area and with a max altitude of 50 m.
Two systems I’m considering are Pozyx (looks to be Ardupilot-ready: https://ardupilot.org/copter/docs/common-pozyx.html) and Ciholas. Then there is the DWM1000 module itself that might be used directly (the same chip is used by both Pozyx and Ciholas).
Does anyone have experience with using these systems and can comment on the pros/cons? Am I crazy to even consider using UWB over GPS-RTK? The UWB tags seem cheaper, but they would need some number of anchors positioned around the flying area.

Tailsitter not able to fly in SITL
@phunthomas wrote:
I’m trying hard to get the default tailsitter model flying in SITL but without success so far. I’m running ./sim_vehicle.py -v ArduPlane -f plane-tailsitter -w --console --map and after initialisation the hdg keeps turning, roll changes a lot and pitch is -89. AHRS and EKF is mostly red. When I change to qloiter or qhover the pitch changes to 0, roll also moves to 0 but hdg keeps changing. Trying to arm I get the message gyros inconsitent. Turning off the pre arm checks and setting rc 3 to 2000 the current goes to 50A but the tailsitter stays on ground and doesnt move.
I started with default params and also played around with
AHRS_EKF_TYPE 0 and 3
EK2_ENABLE 0 and 1
EK3_ENABLE 0 and 1
but never got it working.
I have no problem taking off and flying the dafault quadplane. I’m using latest master.
Any ideas what I’m doing wrong?thanks and best

Quadplane with no control surfaces?
@emilalbert wrote:
Hello I just stumbled over this exciting webpage.
I had the following idea: when building a quadplane with four quad motors for lifting, and one motor for forward flight, could you just leave out all the control surfaces? The quad motors should give full control over all axes. Maybe that does not work at higher speeds though?

Pixhawk 2.4.6 and Taranis Plus simulated Failsafe
@Shamrock wrote:
Setup the Failsafe function up on my Pixhawk 2.4.6 and Taranis X9D. Once completed I decided to run a test. Using the Failsafe page in Mission Planner, I turned off the Taranis X9D, which was in Stabilize mode it changed to RTL then Land. Test seemed to work, so set Taranis X9D to Loiter mode and back to Stabilize mode to reset system again. But the Pixhawk did not want to reset, ran reset profile again still nothing. The only indication I have on the Pixhawk is (two) Green LED's (one) LT. and (one) RT. with a Yellow and Blue on LT. side of Pixhawk. Have no control of drone at this point. Any help with resetting the Pixhawk 2.4.6 would be greatly appreciated.

Elevator control of tiltrotor tilt angle

Does vectored yaw only work for rudder input? The convergence tilts both front motors fore and aft with elevator input, but I dont think arduplane does that.
