Failure when selecting different UDP port

[KaiBotics]

epc.tofCam660.tofCam660.TOFcam660 allows specifying the UDP port to which the camera should stream data. When selecting a port other than the default port, no data can be received.

Minimum (not) working example:

from epc.tofCam660.tofCam660 import TOFcam660

cam = TOFcam660(udp_port=45455)
data = cam.get_distance_image()

leads to the following error message: 2025-06-19 13:44:49,183: ERROR [TOFcam660] - Failed to receive image data: list index out of range (tofCam660.py:332)

Looking into the code it is quite clear that locally, the UDP port is opened at the right port but the port number is never transmitted to the camera, which consequently streams to the default UDP port 45454, regardless of the configuration.

You're right, this feature is misleading and was initially added for debugging reasons. As of now, the TOFcam660 cannot change udp port. However, we are working on a solution for that.

OK, great. In the meantime we found a workaround by running an additional service on the default udp port that redirects incoming packets to other custom ports depending on their origin IP address. This enables us to run multiple streams on one Ethernet interface.
