ouster_fix_ip - IRS-group/isr_tiago_docs GitHub Wiki
To access the Ouster consistently they provide a hostname that is converted to an IP. This only seems to work when there is internet.
To guarantee Ouster operation in all scenarios, we fixed Ouster IP to:
192.168.1.50
To do this we used the following command on a terminal, where x.x.x.x is the current sensor IP and y.y.y.y is the new static IP you want to use:
curl -i -X PUT http://x.x.x.x/api/v1/system/network/ipv4/override -H 'Content-Type: application/json' --data-raw '"y.y.y.y/24"'
To revert this process go to the browser and type the ip in the webpage bar. In configuration you can reset network configurations.
