Looking at this guide:

VOXL m500 Using VIO

ModalAI technical documentation for VOXL and VOXL 2 Companion Computers for PX4 and ArduPilot Obstacle Avoidance and GPS-denied navigation, assembled in the USA

ModalAI Technical Docs (docs.modalai.com)

I seem to be able to run some of the commands, but not all of them:

voxl:/etc/modalai$ voxl-qvio-server-configure
bash: voxl-qvio-server-configure: command not found
voxl:/etc/modalai$ 

voxl-qvio-server-configure in particular isn't available, but the service seems to be running anyway, however voxl-qvio-client also doesn't work so it's hard to verify that it really is indeed the case of it working - looking for a way to fly without GPS initialization indoors

@Steve-Sager said in Issues with Docker, and WiFi connection:

The WiFi on the aircraft will not connect to the local guest WiFi network (while in station mode) even after following the steps in the instructions

Have you tried \ as an escape char before the _ or space of your wifi name in order to get it to connect (when running the adb shell voxl-wifi station <name> <password> command)

@Steve-Sager said in Issues with Docker, and WiFi connection:

@Cristian-Adam Yes the wifi ID name I'm trying to connect to has spaces, but to get around that you can just put a underscore where the space would be.

I'm not understanding if this means you were able to get the wifi working via a work-around or not, I needed to escape the underscore as well

does your wifi that it can't connect to have any special characters in the name or password that need to be escaped? (like spaces)

Trying to follow this ros_environment guide

that came about from the mavros page indicating docker is on the drone/needed to run stuff, but docker-on-voxl seems to be out of date, so figuring out how to run docker on voxl is being challenging - loading voxl-docker support seems like it worked correctly however -

unable to run

docker load -i roskinetic-xenial_v1_0.tgz

it errors out with:

ERRO[0511] Handler for POST /v1.21/images/load returned error: Untar re-exec error: exit status 1: output: write /482b910388d5d604cb01d5c10b07ab3dcf243a34d4f539749fe9249671a41856/layer.tar: no space left on device

I have tried running this from the /data directory where there is space, but I am not sure how to re-map where docker expands images into or if I can (should) use the SD card slot for this instead

There seems to be room on the disk, just not where it's being run from:
