My mission is to make my drone fly without GPS, i thought to connect optical flow to the drone, which i believe help the drone to save its position(even if there is wind).
So my Question is - is it really going to help me to save position? or i have to add something else?
@Guohao91 I received this two errors:

But the problem is, when in the callback function, I am trying to set value of a parameter like
vehicle.parameters["param1"]=1.0,
I am getting "error timeout setting parameter PARAM1 to 1.0", although that parameter is being set to 1.0. And in some cases, it is giving rise to "CPU load reaching 100% " in pixhawk cube 2.1.
Any solution to resolve this?
TELEM2="-A udp:127.0.0.1:14540". I am assming this is do-able and it is just me! Any ideas?
Hi there. I'm trying to connect dronekit to my 3dr solo. It's worked fine before with a small nanoPI payload computer over UDP using python 2.7. Now I'm trying to connect a Jetson Nano computer with the same 3dr solo using udp and python 3. I get connected, but just after connecting the console reads:
CRITICAL:Autopilot:APM:Copter solo-1.3.1
CRITICAL:autopilot:PX4: 5e693274 Nuttx: d48fa307
etc...
I have 3D GPS lock and the vehicle reports that it's armable and in Standby-mode.
I flies fine using the remote control, but I cannot get my python script to change vehicle mode to guided or anything else.
I suspect it's because of the CRITICAL statement, but I cant see what should be wrong or critical. QgroundControl reports no errors as well, so it seems to be related to dronekit.
