I'm trying to get data from my 3d printer through tcp port 35. I was able to sniff the packages between my computer and the printer with wireshark, but I was not able to get data with node red. It seems that there is a communication with custom json. I've tried to inject the json data directly through the tcp request node but I got a connection error.
I've attached some pictures of the wireshark dump because I am not able to upload the dump as zip file.
There are 3 packages sent repeatedly:
- from the host to the printer with a length of 54 bytes
- from the host to the printer with a length of 183 bytes including the json data
- from the printer to the host with a length of 775 bytes with the result
Is there anyone who is familiar with wireshark who can help me here?
Thanks in advance
