Hello Everyone,
I am currently trying to fly Starling2 drone indoor in off-board mode. I was trying to take-off and hover the drone at at specific height drone was holding position higher than I programmed it to be. And when I gave the landing command drone came close to the ground but did not land and then it started to move around even when the ros2 node that was controlling didn't have any other function other than to hold the position at given height. also drone is unable to repeat the hover program consistently sometimes it works sometimes it starts to drift then loses the control.
when I started to monitor its position estimation from ros topic /fmu/out/vehicle_local_position I can see that position estimation is off. like for example when given the land command drone gets close to ground but does not land, in this situation /fmu/out/vehicle_local_position shows z-position is ~0.0m when I engaged the kill switch to stop the drone and land it on the ground the /fmu/out/vehicle_local_position shows positive value for z-position ~0.2-0.5m.
I have tried recalibrating sensors but it still behaves the same. has anyone else had the same issue and how can I find the work around it

@ApoorvThapliyal Thank you for your help. also I was able to work with jazzy by only subscribing and printing with node. since error only occurred when I tried to echo the topic and not when another node is subscribing it. but using docker seems like most viable option to me since I m using ubuntu 24.04. Thank you for your help again

@ApoorvThapliyal does my ros2 version on my computer could be an issue. I have ros2 jazzy running on my computer where drone has foxy

@ApoorvThapliyal sorry for the late reply. my drone got bricked so I had to reinstall everything. I am still facing the same issue.

here are the sdk versions
voxl-sdk is 1.6.3
voxl-mpa-to-ros2 0.0.7
voxl-microdds-agent 3.0.0-0
voxl-ros2-foxy 0.0.1
voxl-px4 1.14.0-2.0.133

also one more thing I forgot to mention before was I was initially was not able to see ros2 topics from drone on my computer but when I install netcat on drone then I was able to see those topics. but I still can't echo them

@ApoorvThapliyal

This is how its being showing

@ApoorvThapliyal I forgot to mention that the error occurred on drone side for voxl_mpa_to_ros2_node. While on computer it is not printing anything

@ApoorvThapliyal I was trying to echo /imu_apps

@ApoorvThapliyal, Hi, I set ros domain id on both drone and the pc. they are connected it through the access point. I can ping both drone and pc from one and another and I can even connect drone to qgroundcontrol. That is why I am thinking it might be the ros side issue. I also check for micro dds agent and it was enable and running. I have setup the static ip on drone. I added following command in /etc/dhcpcd.conf file

interface wlan0
static ip_address=192.168.x.xx/24
static routers=192.168.x.xx
static domain_name_servers=8.8.8.8

Let me know if you need anything else you need.
