<![CDATA[TELEMETRY DATA]]>Hello support,

How can I get telemetry data for my starling 2 drone? Is there an App available?

Thanks.

Regards,
Taiwo

Why do I have that unpredictable behavior ? I have attached images of my controller to show the toggling i meant.

Kindly advice.

What SDK version are you using. Anything over version 1.5.3, we recommend using the openvins VIO implementation rather than Qvio.

Typically a different XYZ value from actual indicates VIO reset during flight. What you want to try 1st is a bench test to confirm vio is set up correctly. Essentially power up the drone on a level surface, then connect to it and bring up voxl-portal (http://<ip of the drone>) and goto the VIO page. The page will show the drone in local space (0,0,0 xyz) if you pick up the drone and move it in a 3D plus pattern the vio page in portal should reflect that. If it does not, then we a configuration issue.

I have another issue, when i toggle the controller from manual mode to position mode, sometimes he drone holds it height, but sometimes, it just flies away and crashes. I have calibrated the compass, gyro and accelerometer, it still exhibit same behavior (infact thats how all the drones behave), so that means there is something I am not doing right, or I am missing. I ran ros2 topic echo /fmu/out/vehicle_odometry to see whats happening with the VIO, this was the output:

reset_counter: 25
quality: 0

This is weird because the drone is on the ground, why is my Z reading -7.352?
Also, i keep getting heading_good_for_control: False (what can i do to fix it?)

I moved the drone round the lab to capture features, yet the quality is still zero, and why does it keep resetting (from the reset_counter)?.

Kindly help.
Thanks
