Modal M500 Voxl Streamer
-
I need to take screenshots off the hires camera feed from the M500 every quarter second and save the screenshots to my computer. Is there a way to modify the voxl streamer script or another script on board the aircraft to do this?
-
@Samuel-Bryan This command:
voxl-send-command hires_snapshot snapshotwill take a snapshot and save it to the/data/snapshotsdirectory. You could write a small script to call that every quarter second. -
@Eric-Katzfey I tried that command, but I got the error "Unable to find valid pipe that accepts control commands at: hires_snapshot". I am using voxl-suite 0.9.4, with system image 4.0.0.

@Samuel-Bryan Can you update to the latest SDK and try with that? With what you have now what do you see in the
/run/mpadirectory? -
@Eric-Katzfey I tried update it with the latest SDK but it says it is out of space. I have a Windows machine, are there instructions for installing the latest SDK onto the Modal M500?
-
@Samuel-Bryan I would recommend setting up a Linux workstation (ideally Ubuntu) as you'll have an easier time working with that.
Can you post a screenshot or paste the output of the error you're getting?

I was able to get the SDK upgraded to Voxl 1.2.0. However now it won't communicate with Q Ground Control. When I open it, it shows that it is disconnected despite there being a wifi connection between between the laptop and the M500. It connects to the laptop fine and I can SSH into the aircraft. Is there a setting somewhere on the aircraft that I have to change for it to connect with QGC again?
-
@Eric-Katzfey Do you have a list of voxl-send-command commands, or is it listed in the documentation somewhere?

@Samuel-Bryan There are some examples here: https://docs.modalai.com/mpa-camera-interface/#sending-commands-back-to-the-server
