Hi @erik,
I flashed the POE device with the new config.json bootloader to set a static IP, and power cycled the POE Camera but do not see the device via ping or dai.getAllAvailableDevices().
When I try to ping the new IP 172.16.15.201 ping halts and does not even say the host is unreachable. The old IP before flashing was assigned via DHCP as 172.16.15.70 so if I could reach the old IP, I don't see why I couldn't have reached the new one. Do you have any suggestions?
For reference I created a script below (thanks GitHub CoPilot) to create a new JSON file that was used to flash the device via "python3 bootloader_config.py flash new_config.json". bootloader_config.py said the flash was successful.
