DMXsend problems with certain devices

[tlundi60]

Hello and thanks again for the great library
It works really well in my experiments. (dmx send)
but with two devices (cheap goods) the device reports a DMX signal
but not responding to input.
I've done some research and have an opinion on the issue
timing or DMX refresh rate ;

Is there anything you can change to see if it has an impact?

Hi,
if you thing this is some sort of overload, you can simply try to reduce the from the Art-Net source. Maybe the software has on option for frames per second (FPS)?
My library puts out what it can/gets.

If this is not possible, you can implement a "rate limiter" in the onDmxFrame() function.

static int counter = 0;
counter++;
if ((counter % 4) == 0) {
  return;
}

This will drop every 4th frame. This will give your device a bit more time to process the data.

Hello and thanks for the support
I'll experiment a little, I suspect that the cheap DMX devices probably don't buffer the input, because after a few tries I have the DMX commands displayed for about 1-2 seconds before the lamp goes dark again
