I know this code is really old, but has anybody had troubles with this error?
Traceback (most recent call last):

It's a really frustrating issue, and it happens even with a different bluetooth adapter

Yes, run the command as root, or use setcap on bluepy
sudo setcap cap_net_raw+e /home/waylonflinn/.local/lib/python3.8/site-packages/bluepy/bluepy-helper
sudo setcap cap_net_admin+eip /home/waylonflinn/.local/lib/python3.8/site-packages/bluepy/bluepy-helper

Ok thanks now it doesn't make that error anymore. But looks like my lightouses don't seem to care 😢
The script exits without any error but the stations do not start

Update: just noticed the script is supposed to say when it found a lighthouse. But I'm getting no output whatsoever, so i guess it's not finding them

Hi,

Please take look at https://github.com/DavidRisch/steamvr_utils, it expnads on this script, and maybe it will work for you.

Fixed the problem, I forgot my base stations where 1.0 and not 2.0 so it would not be able to find them anyway. https://github.com/risa2000/lhctrl this is the script for 1.0 if anyone is interested
Thanks for the help :)
