voxl-wifi command line parameters
Yesterday I spent like two hours figuring out why my voxl won't connect to my AP at work. After I had it, I felt kind of stupid:
I simply copy&pasted the password but apparently it contained a dollar sign so only the prefix ended up in wpa-suppicant.conf and the rest was interpreted as bash variable. I guess the script should expect a single quoted psswd to prevent these kinds of user errors or explicitly check.
Also, a language setting for wpa-supplicant would be neat. Our wifi was configured to use channel 13, which is apparently only recognized with a "de" setting in the config.
I can also make a PR later. Thanks!
