Hello guys,

I just reinstalled from scratch the SDK and the operating system of my voxl2 (from flashing the firmware to SDK 1.2). I can access the voxl2 portal, seeing cameras and similar. However, when I try to configure my UAV using QGroundControl, it is very slow to download the parameter list (20% of package loss rate). However, when it finished I had the error: Unable to retrieve the full set of parameters. 

Sadly, in this state, I cannot access the configuration options of Qground (ie. RC configuration, flight mode and similar). 
Where I am wrong? Before reinstalling everything, Qground was working!

Thanks,

@jocacace13 It sounds like you have a weak network connection between voxl2 and your host machine.

@tom Thanks for the reply. I thought the same at the start. I also tried connecting with the ethernet cable, and the results were the same. Do you mind if any other issues can cause the same behaviour?
