Hi Kristoffer

Kristoffer DEPTHAI_PROTOCOL: tcpip

Don't use environment variables. Especially not the protocol. The device discovery is UDP, which might be blocked after using this setting.

Kristoffer Do you use the internal Windows DHCP server or a third party program?

DHCP on a router connected to the switch.

Kristoffer I am also interested in how you installed Depthai and its dependencies.

Installed via installer (so dependencies are installed). Then went to some custom directory, pulled depthai-python, did install_requirements.py inside examples/ and then inside /utilities as well. Ran python examples/mixed/multiple_devices.py.

EDIT: also used python3.11 since 3.12 is not currently supported unless on the python312 branch.

Thanks,
Jaka
