Drone losing position / crashing in Offboard mode
-
@Eric-Katzfey I tried using the modalai forked repo in the cube and this is the outcome, when I switch to offboard it is still going to home but not like crashing how it was previously, but goes near home and hovers very close to the ground, and I get autopilot disengaged and switches to land mode and lands.
@Jetson-Nano Interesting. Can you share the log from that flight?

Hey @Eric-Katzfey, here are the logs for the flight test.
In this flight test, I set the offboard mode to trajectory and did the flight test
In this flight test, I changed the offboard mode to figure_eight and still the result is same, it goes very close to ground at 0,0,0 and hovers there.

@Jetson-Nano I'm guessing that you don't have an odometry mavlink stream setup so the Cube Orange isn't sending out vehicle odometry mavlink packets that the offboard mode needs.

@Eric-Katzfey How do I setup that?
@Jetson-Nano I would recommend reading through the PX4 documentataion on Mavlink messaging. It discusses how to enable streams. https://docs.px4.io/v1.14/en/middleware/mavlink.html

Thank you @Eric-Katzfey , I'll check and get back if needed anything.

@Jetson-Nano The command would be something like
mavlink stream -r 30 -s ODOMETRY -u 14556and would be added to one of the startup files. -

@Jetson-Nano The command is the same regardless of whether the message is custom or not. Another thing you can do is enable some of the debug flags available with
voxl-vision-hubto see things like which mavlink messages it is receiving and which mavlink messages it is sending out. There are a variety of flags to choose from and that would help to figure out what is going wrong. -

Hey @Eric-Katzfey , I think I solved it. I got the odometry stream to VOXL2 from Cube. I had to run
mavlink stream -r 30 -s ODOMETRY -d /dev/ttyS0after this I got odometry stream on the
voxl-inspect-mavlink mavlink_onboard

@Eric-Katzfey I haven't done the flight test. I'll do the flight test and get back to you.

@Eric-Katzfey I haven't done the flight test. I'll do the flight test and get back to you.
@Eric-Katzfey , I did the flight test and it works fine. Thank you.
But there is a problem, when I am checked 1st time it worked fine, later after a reboot and once again I ran the Mavlink Odometry stream, the terminal was lagging. The terminal with the output of voxl-inspect-mavlink mavlink_onboard this is lagging. The Odometry Hz was somewhere around 5 - 10, all the output in the terminal was lagging, so I though it was some WiFi issue and again tested offboard mode, but this time the drone went back to home.
So I rebooted the system and again ran the mavlink stream and waited for sometime until the lag in the voxl terminal is not there anymore, then when I tested offboard it was fine. I tried both figure eight and trajectory, both worked fine. I will attach the logs, can you please tell what might have caused the lag?

And I have one more question @Eric-Katzfey , I have to start the mavlink stream everytime. Is there a way to start the mavlink stream as soon the system is powered on?

@Jetson-Nano Yes, there is a way to do that. Probably best to consult the PX4 documentation or ask on the PX4 forum for best way to do that on a Cube Orange.

@Eric-Katzfey What about the previous question I asked?
@Jetson-Nano I really don't know what would cause that lag. You say it goes away if you wait awhile. How long do you have to wait for that to happen? And what is the baud rate of the UART that connects the CUBE Orange to VOXL 2? It's possible that the UART has too much data going over it and needs a higher baudrate.

@Eric-Katzfey The baudrate is 921600, sometimes I'll have to wait for more than 5 minutes and sometimes within seconds it will be ready to fly with required Hz
