Flow of command while switching from guided to loiter
@Asher wrote:
I am preparing for a test where I will use a companion computer to send position targets to the drone frequently.
During my initial tests, I need to make sure I can recover control over the copter in loiter mode if anything about the copter makes me think the test is failing. I just want to make sure I understand the flow of control in this situation.
- I turn on the copter
- I connect my remote which will have ch5 high set to loiter
- I set ch5 to high
- I connect my companion computer which will send a change mode to guided request through mavlink.
- At this point, is the copter in guided? Even though ch5 is still set to loiter?
- I want to switch back to loiter, so what can I do with ch5 on my remote to set it to loiter?
Do I need to switch ch5 from low to high again? Causing the copter to be in the low-set flight mode momentarily? What if I had both ch5 high and low set to loiter? Like in the Arducopter code, is the flight mode changed simply when the RC input transitions from one range to the next?
Thanks to anyone who can help clarify! Just trying to cover my bases in case my code has bugs (and I can assure you that it has bugs).

Calibrage esc sur pixhawk
@tristanyves wrote:
Bonjour à tous.
Je bloque sur un problème de calibrage sur un controleur de vol pixhawk 2.4.8
quand je fais le calibrage les 6 moteurs en même temps tous ce passe bien ,les moteurs fonctionnent
tous instantanément et la variation est parfaite ,mais quand je redebranche la batterie pour réinitialiser la pixhawk,la variation de vitesse a un temps de décalage et la courbe varie seulement sur les premier 50%.
Merci pour vos réponses si quelqu’un a déjà eu ce problème.

Unknown crashes

Hi
I am having this unknown crash problem when hovering but only sometimes. I have done full missions before but about 2/10 flights result in a crash as if the motor/s lose power and start tumbling down. Here is the log file : https://drive.google.com/file/d/15J3tNBz5YqSBHfddGQIRICnn79sj2xAX/view?usp=sharingAny help would be appreciated !

2 Pixhawks for 1 Drone
@Renzo_Zuleta wrote:
Hello, i am currently seeing older videos and stories of long time flights being dropped out because some pixhawk failure. Now the questions i am enquiring is, is there a way to attatch 2 pixhawks onto 1 plane in order for redundancy. So incase the plane’s primary pixhawk goes malfunctions, is there a way for it to switch to the second pixhawk to continue its desired course of action?

Simulated copter lands when switching to Loiter
@armadillo wrote:
I am getting some strange behaviour from my simulated vehicles, the setup is the following:
Starting a simulated vehicle, e.g. via sim_vehicle.py -v ArduCopter
Connecting via udp port 14550 on QGroundControl
Taking off via the takeoff button of QGC and then clicking on the map to send the vehicle towards a GOTO point (vehicle switches to GUIDED).
If I switch to LOITER (via the drop down mode menu), the vehicle stops and immediately descends, lands and disarms. It acts as if I have switched to LAND, although the mode is clearly LOITER.Am I missing something?

How to pass it on
@bok555 wrote:
Last June we had help to install the driver: (https://github.com/ArduPilot/ardupilot/blob/master/libraries/AP_GPS/AP_GPS_NMEA.cpp)
to include the GPHDT sentence from our GPS Compass (Hemisphere V103). And it has worked fine apart from the fact that it is not being registered as a compass in ArduPilot.
Here it is in my back garden showing a YAW of 89.66, and the HDT message from the V103 says 89.79 and 89.96 so that is only minor differences. See the images here: https://drive.google.com/drive/folders/1JBcYNLrUGkxz3B5xXilkwony0HbonoFl?usp=sharing
So, how do we pass it on, so that it is shown on the HW ID list as a compass ? Is it maybe an amendment to the driver, that is needed ?

Bad LiDAR health when transmitter is ON
@Jet94 wrote:
Setup:
- Cube Black running AC4.0.2 (parameters attached)
- LidarLite v3 plugged in through PWM
- FrSKY X8R plugged in through the SBUS port
The rangefinder stops working as soon as I turn my transmitter (Taranis) ON, the ‘sonarrange’ value stops updating and the display shows ‘Bad LiDAR Health’.
It is however all fine if I power on the quad with the transmitter off…
I have tried power them separately but the same thing happens. Any thoughts on what I should be looking at?MP1.3.70 AC4.0.2 HPO014.param (17.9 KB)

Taranis X9D 6-position switch for flight mode selection
@neo2001 wrote:
A while ago, I added a 6-position switch to my X9D (OpenTX 2.3.5) and set it up as S3. On the radio itself, I’ve selected S3_1 to S3_6 to select the OpenTX flight modes and named them in the same order I have selected on the flight controller (I know this is not needed to change the actual flight mode, but I wanted it to be like that).
Now I want the same switch to select flight modes on my ArduCopter Multicopter (Pixhawk with S-BUS R-XSR receiver). I’ve mapped S3 to channel 5, which seems to be default for flight mode selection on Copter. But the PWM ranges between switch steps do not “fit”. I’m not sure which way I should choose to correct this. With OpenTX and some logical switches or with a curve? Or even change something on the flight controller?
I’m looking for the “recommended” or least complicated way to do this.

Mavproxy as exclusively proxy, no commands
@Asher wrote:
Hello,
I am trying to test some new ground control software I have been working on. I’ve tested thoroughly using SITLs and now I want to try it outside on real hardware.
For this test, I want to use MavProxy with two outs, one out for my GCS and another for mission planner. However, I want my GCS software to be the only one sending anything back to the drone though MavProxy. This means I need the Mission Planner out to have “set mavfwd false” (I’ve got that part down) and I also want mavproxy itself to send no Mavlink packets to the drone. I think Mavproxy will request parameters etc. to be sent on startup. I don’t want that to happen, I only want Mavproxy to forward mavlink packets to/from my GCS.
Can mavproxy be operated this way or do I need to look somewhere else?
Thanks for any insight!

Hexacopter Crash - Loiter - Stable then a random flip
@tremmert wrote:
Hello,
I am struggling to understand why I crashed in Loiter mode with my Hexacopter. I took off and held the aircraft stable at about 2m, then it randomly flipped over and went straight into the ground. Ugh…Running the following hardware:
- Optical Flow
- LedderTech Lidar for altitude
- GPS disabled
All sensor values look OK to me when reviewing. Does anything stand out to you or can you suggest what I can look at?

Using Mavlink for avoidance via companion computer
@JohnLongland wrote:
Good day all
Getting my feet wet with Mavlink.
I would like to add object avoidance to my drone and I have been reading a few
posts on this topic. Including this one:My setup -
quad-copter
pixhawk 2.4.8
450 frame
Sensor TFMiniPlus ( lidar )
companion computer : Teensy 4.0( I actually have two quads. This one is based on the pixhawk 2.4.8 and I am
starting with this one as this is my “try-it-first-drone”. But ultimately I want
to transfer it to my other quad based on the Pixhack V3x )On the 2.4.8 I am running copter 3.55 and on the pixhack V3 I am runing 4.06.
I have coded the sensor-interface code and I can also receive the heartbeat messages from the 2.4.8.
Port 2 on Teensy : connected to drone ( Mavlink )
Port 3 on Teensy : connected to TFmini+I have checked the contents of the message been sent to the drone and it seems correct. BUt my MP still says : Bad LiDAR health. Which to me means it is not receiving the messages I am sending.
Oh… my settings are
RNGFND_ORIENT 0
RNGFND_TYPE 10
PRX_TYPE 4Now my question:
From what I have been reading , certain commands ( like Param request ) will result in a response.
Does the mavlink message MAVLINK DISTANCE MESSAGE also yield a response that I can look out for ? If so, then I can use the response or lack thereof, to judge if the FC is receiving my message ?I couldn’t find a place where MP can show me the mavlink messages, hoping I can use that to see if the FC is receiving my message.
Many thanks

What to do in home isolation? Build another rover!
@count74 wrote:
Here in Germany we are supposed to stay at home (this will probably turn into a curfew soon), so I decided to build a new rover. It is just the chassis with RC control for now:
https://drive.google.com/open?id=1kVoN3iVS6OF8vqLkbPdvyrAoOHFqO9aP
The body is a Hammond aluminium case, the rover is upside down in the pictures. It is driven by two Planet Hobby 510kV brushless outrunners powered by two 4000mAh 2S lipos in parallel. The wheels are 1/8th scale RC wheels, fixed to 8mm solid steel axles with 17mm hex adapters. The drivetrain has a ratio of 1:7.5. First stage are pinion gears, the second stage is a GT2 belt drive. The ESCs are sensored/sensorless 60A car ESCs for now, VESCs are in transit.

Strange Compass Motor Calibration results
@vosair wrote:
Has anyone ever seen anything like this? No interference and then a huge spike? It seems to fly pretty good with the exception of the compass health not being very good when I throttle up or down, which made me think I should do a compass motor calibration. The GPS/Compass I’m using is the mRo Location One.
