dmx | A Simple Go library to send DMX messages

I have a device in the network at 192.168.123.204 which broadcasts UDP datagrams(Artnet) as 2.168.123.204 to 2.255.255.255:6454. (The network address is 192.168.123.204 but the datagram is sent with 2.168.123.204 as source.) The address 2.255.255.255 can't be changed (no setting for that).

My Python script runs on the device 192.168.123.148. I can receive the datagrams there with wireshark: but a Python socket bound to 0.0.0.0:6454 can't receive them. Binding it to 2.168.123.204 or 2.255.255.255 does not work. The script is working, since I can receive Packets from 127.0.0.1.

If it can't be solved with Python can I redirect the UDP broadcast with iptables (linux)?

After about a year of writing these files by hand, I'm looking for a way to generate QC files. I have tried just hard coding the commands in a list and just writing out the the command and its value as text, but this feels very brute force-ish, and I'm figuring there must be a more elegant way to populating the file. If it matters, my end goal turning this into an add-on for blender. EDIT: Adding example output/QC file

I have a page with 50 records on and when you save a value it fires off 31 form params for each of the 50 records. So this means a lot of code which wont compile because of JVM limits. It's also very much repeatable code.

So I wanted to create a method like this:

I want to learn python and gekko but i have an issue. I want to write this matlab code again with gekko, for learning gekko. Here is matlab code that is working very well:

i am trying android WorkManager, The code is throwing error "More than one file was found with OS independent path 'META-INF/proguard/androidx-annotations.pro" when running, I tried the following answer, it was not helpful.

i am getting:

TypeError: Cannot read property 'split' of null

in error object from mongoose.connect, in CircleCI, and later on tests timeout, first one fails with 500 error. It seems like mongo/mongoose error, am i doing something wrong with tests, i mean i am sure i do, since with simple non-async test i am not getting this error. Btw, this works fine locally, no errors, just fails at CircleCI tests.

I am starting a project in java where I want to control a Lights from my computer using a Terminal Window. I am using a piece of hardware called an Enttec Open DMX USB Converter. So I am writing this question, to ask the community if anyone has an idea of how to send data to this Enttec device to control lights. Where would I start? I already know how to write terminal command aliases and execute .jar files so I don't need help with that.

What I have tried so far is to look at an open source project called "Open Lighting Project" that I know can control the device and learn how it works and how can possibly make my program. But I got stuck looking at the java code folder in the Github Repository, trying to find a DmxData.java class that it says OlaClient.java is importing. So I am very confused where it is getting it from.

I have also tried looking at the developer tools on the Enttec Website, and they don't work. More Specifically I looked at the file package called Java Wrapper, and tried running the test and kept failing every time with different errors.

These are the links:

Any help would be appreciated!

Thanks!

I have a Django application which works just fine. Problem is that it needs to be migrated and that brings some changes.

Whole application used to be in PostgreSQL schema intake.
Problem is with following models.

I have searched for 2 days and found many, many questions/answers to what appears to be this same issue, with some differences, however none really seem to provide a solution.

I am implementing a library for controlling a DMX system (ColorKinetics devices) directly without an OEM controller. This involves communicating with an Ethernet-enabled power supply (PDS) connected to my home LAN, through a router, which drives the lighting fixtures. The PDS operates on a specific port (6038) and responds to properly formatted datagrams broadcast over the network.

I can successfully broadcast a simple DMX message (Header + DMX data), which gets picked up by the PDS and applied to connected lighting fixtures, so one-way communication is not an issue.

My issue is that I am now trying to implement a device discovery function to detect the PDS(s) and attached lights on the LAN, and I am not able to receive datagrams which are (absolutely) being sent back from the PDS. I can successfully transmit a datagram which instructs the devices to reply, and I can see the reply coming back in WireShark, but my application does not detect the reply.

I also tried running a simple listener app on another machine, which could detect the initial broadcast, but could not hear the return datagram either, however I figure this wouldn't work since the return packet is addressed to the original sender IP address.

I initially tried implementing via UdpClient, then via Sockets, and both produce the same result no matter what options and parameters I seem to specify.

Here is my current, very simple code to test functionality, currently using Sockets.
