I’m having a small problem with a 250 quad. After changing the propellers to have less noise and tuning the pids accordingly I got a nice flight. Especially had to lower the P. Now after a week trying again it is not working anymore. It looks like trembling and I have no control over it. Looking at the logs I see that the motors 1&3 are alternating to 1800 and motors 2&4. Not sure where to look. I’ve tried adjusting the pids again, but not finding position where it goes away. Any clues? Thanks!
I’m Alessio from Florence Italy, I work with Pixhawk and Arducopter since 2014 , but I found a problem with a new machine.I start with Pixhawk 2.4.8 clone , FW 3.6.1 Copter , Serial 4 , protocol 10 , baud rate 57, I can’t found the signal from pin 2 (TX) of the Serial 4/5 connector , but if I change protocol to Mav (1) I found output serial data.
What can it be that escapes me?
Thanks
Node 2: ATS10 = 2, ATS11 =don’t care, AT+F0=1,3, AT+F1=3,1 // forward 1->3, and 3->1
after setting up , my flight controller rfd900x (node 1) get binds with gcs rfd900x (node 3) in between i just powered on node2 rfd900x … Seems to be the data is not relayed via node 2
please help me how to make the setup for data communication relay
My file logs size in Pixhawk 2.1 (the cube) are about 80MB for 30 minutes flight. I thought this was normal but a frind of mine told me his log files are never bigger than 5MB. My parameter LOG_BITMASK=65535.
How can i achieve an autonomous mission without a radio controller, my supplier has failed to send it to me and the demo is in 4days to come please help!
Hye guys can anyone guide me from a-z how to make the remote can control the motor that connected to apm 2.6.
My project is to build an autonomous boat. And the due date is this wednesday. I hope someone can help me go through all of the step. I will appreciate so much for your help.
we are testing Here+ RTK GPS on our surveys using NTRIP connection with success results, but I have some questions regarding to this.
I suppose “RTCM Base” are the absolute coordinates of the antenna which give us our absolute position on site. Is that right?
In this case, that given position is the one I use to start surveying and guide the Rover with good accuracy. But the thing is that I don’t see this absolute coordinates anywhere and if I use the “Save Current Position” button in order to save it it, gives strange numbers starting with ceros.
Is there anyway to know our global position?

Hello,
When I try to use my Ardupilot 2.8, I faced this problem
The gps is not fixed all the time. I tried to use it outdoor but no response
Any can help me to solve this problem?
I have two TS100 mini RadioLink GPS/Compass (QMC5883L) bought at different times. Both should be ok.
And they’re both works good on Nuttx 3.6.1rc2 on my pixracer.
But they both doesn’t work normally nor on first 3.6 versions nor on latest rc2.
So all what I found at the moment (this is only on ChibiOs):
Compass #1 (external) hangs in 90% cases in 5-20 seconds after a battery connection. If the compass is selected as primary then “Bad compass health” error also appears.
Compass #1 never hangs after soft reboot (CTRL+F => reboot pixhawk)
Weird! But opposite to compass #1, compass #3does hang after a soft reboot!
Compasses #1 (external) and #2 (internal) reading are different after hard reboot and soft reboot. But compass #3 readings are always the same.
I.e. on every battery connection mx=-207, mx2=330; but after every soft reboot: mx=319, mx2=140
Opposite to that, mx3 reading always the same regardless of reboots.
This all is repeatable and is not depends on power source. I did tests with battery and USB power.
So, how it looks like: I connect the power => FC boot up and external compass hangs after a few seconds. Reboot via mavlink command => FC boot up and external compass works good this time but internal compass #3 hangs.
Hope these facts could help someone to understand on what’s going on. Because I have no idea what to check further.
I live in an area where a snow plow is not needed but this just begs for ArduRover and I could make it do something useful, but I don’t believe the specs. Anybody familiar with it? It sounds too good to be true: Weighs 230kg, battery life is 36 hours continuous, charges in 5-8 hours. What!!! Costs just $200!
Hi there I am having some problem with my pixhawk, it was working all fine but when I powered it up using power module it started giving some problems
on powering up it is giving main rgb light continuously red
Both power lights of fmu and i/o are still
On connecting with mission planner the com 16 port is not visible
When I insert the SD card with my SD card adapter on my pc the SD card is also not visible on my pc
Can anyone please solve my problem, I guess my power module was faulty, though I didn’t checked it in the start but the controller was working fine when it was plugged with data cable with mypc also the buzzer is not working and safety switch is not giving any light
I’m getting a PreArm: GPS 2 failing configuration checks and a message saying GPS 2: was not found
I never got this error until I updated from 3.57. I also have GPS_RAW_DATA set to 0: Disabled
How can I disable this message?
I just tried to interface pixhawk with garmin lidar lite v3 using pwm method as mentioned in wiki , but i want to do the obstacle avoidance for UAV with the same setup.Could anyone provide some info on that that how to start or what to do
Hello, I have a project on AI/object avoidance and i am trying to find a direction here. I plan to run a 3D drone simulation using SITL and gazebo to train my drone. I would like to ask:
Do i need to program the dynamics of the drone if i am using gazebo with ROS?
If ROS have the dynamics of quadcopter, then i just need give instruction to the drone?
in the end can i transfer the program to my drone after the drone is done training? or is it just for simulation?
do i need anything else other than gazebo/ROS, SITL to train my drone?
Thanks guys. Drone using APM2.6 as flight controller. plan to use Raspi to control the flight controller.
Hi,
1 - Do Arducopter transmits GLOBAL_POSITION_INT_COV messages?
2 - Do Arducopter transmits DISTANCE_SENSOR messages? If not, which message do the Arducopter send that include range finder (I know it sends the data since its available in MP)
I can’t see any of the above messages when trying to interpret the data using an Arduino…
Hello all.
I’ve got a GPS hard mounted in an airplane I’m converting to Pixhawk and AP 3.9.2, and I’d like to use it with the original pixhawk. Can this be done? I found the pinouts and the protocol elsewhere, but I need help that’s more idiot/newbie level. What to hook to what? It’s an early Eagle Tree unit.
Or is it not worth the effort?
