I can connect to the voxl ap and have entered the ip address in voxl-vision-px4.conf. When starting QGronudControl it does not see px4 service. QGroundControl will make a connection using the USB connection.
What am I missing?

Did you restart the voxl-vision-px4 service with 
```
systemctl restart voxl-vision-px4
```
after modifying the config file?

Hi @daboy ,

Can you please describe your setup?  What OS is QGC on?  Ubuntu/MacOS/Win10?

If it's Win10, there's a good chance it's a firewall settings causing you issues.

Otherwise, can you ping the VOXL from the Host computer?  Can you ping the other way around?
