Ruida RMA - Remote Mobile Application

Hi @adammhaile.
Can you please answer a few questions about the “LightBurn Bridge” device?

  1. Can you tell me on which ports I need to send packets so that they reach the laser?
  2. 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
