Hi,

We are trying to capture lidar data from Livox Mid 70 sensor from Rasberry Pi 4, with Python library openpylivox (https://github.com/Livox-SDK/openpylivox)
We have connected the LAN cable from Livox to the Raspberry Pi ethernet port and ran below code (we assigned a static IP to the sensor).

sensor.auto_connect("172.25.25.100")

Note: 172.25.25.100 is the IP address of Rasberry Pi

We are getting this error:
self._cmdSocket.sendto(connect_request, (self._sensorIP, 65000)) OSError: [Errno 22] Invalid argument

Would be very grateful if anyone can help to get this working..

Hi @nikhilpTF ,

I don't know if you managed to get it and I don't know that library, but in case someone finds it useful you can check the user manual (https://www.livoxtech.com/mid-70/downloads) and to try the default config:
"The default subnet masks of the Mid-70 sensors are all 255.255.255.0, and their default gateways are 192.168.1.1."

For example, your IP address could be 192.168.1.5 with the submask 255.255.255.0

I hope it's useful

I am having the same issue with a Livox Tele-15. The address of the Tele-15 is 192.168.2.196. I am running this on a Jetson Xavier. I've set the IP address for eth0 to 192.168.2.1 with netmask 255.255.255.0. When run the demo I get:
airm@CalFixture:~/devl/OpenPyLivox$ python livox_controller_demo.py

Any suggestions?
