Hello Modal AI team,

I am trying to enable and run voxl-io-server. I was successfully able to enable it but when starting the system, it would not run. I ran into this error when I asked for its status

voxl2:/$ systemctl status voxl-io-server
● voxl-io-server.service - voxl-io-server
   Loaded: loaded (/usr/bin/voxl-io-server; enabled; vendor preset: enabled)

Did you try running `voxl-configure-rangefinders`?

Yes I have, and these are the outputs: 

voxl2:/$ voxl-configure-rangefinders
missing required argument

Start wizard with prompts:
voxl-configure-rangefinders

Shortcut configuration arguments for scripted setup.
factory_enable will reset the config file to factory defaults
before enabling the service.

voxl-configure-rangefinders disable
voxl-configure-rangefinders 1_on_m0141
voxl-configure-rangefinders 1_downward_on_m0141
voxl-configure-rangefinders 4_on_m0141
voxl-configure-rangefinders 1_downward_on_m0173
voxl-configure-rangefinders enable

1_downward_on_m0141 is for a downward sensor, this enables mavlink
broadcast to the autopilot as a landing sensor

show this help message:
voxl-configure-rangefinders help

is there a certain option I should select?

@Eric-Katzfey I figured out that I did not need it for my project, Thank you thought!
