Hi @adammhaile.
Can you please answer a few questions about the “LightBurn Bridge” device?
- Can you tell me on which ports I need to send packets so that they reach the laser?
- Will it be enough for me to send the same packets, but instead of the UDP protocol, use the TCP protocol?
P.S. → I will be glad if you can answer my questions. Thanks in advance.

@jkwilborn - Thank you very much for your help.
You helped me a lot.
Can you please do one more thing.
I need you to run one command directly on this device “LightBurn Bridge”:
sudo netstat -tulpn | grep -i ‘LISTEN’
I need to know what other open ports are listening on this device.

Hi @adammhaile,
Can you please answer to my question.
“LightBurn Bridge” use TCP port 5005 instead of UDP ports 50200/40200.
- 0x4C + 2 bytes UDP packet length + UDP packet with checksum.
I need to know, what TCP port using instead of 50207/40207 UDP ports.
Thank you.

Didn’t get any values…
pi@lightburnbridge:~/mjpg-streamer/mjpg-streamer-experimental $ sudo netstat -tulpn | grep -i ‘LISTEN’
pi@lightburnbridge:~/mjpg-streamer/mjpg-streamer-experimental $
Without ‘grep’
pi@lightburnbridge:~/mjpg-streamer/mjpg-streamer-experimental $ sudo netstat -tulpn
