Low latency DMX gear does not work correctly with esp_dmx

[maxroseGIT]

I have a problem on transmitters that transmit DMX512 without much latency (no breaks between data frames).

In my case only the first LEDs respond correctly to the DMX signals send by this type of DMX Controller.

The fixture is self-built with an ESP32-DMX device (DMX shield plus ESP32 from sparkfun)

A more detailed description of my setup (hard+software) is mentioned here in the issue tracker of WLED.

My question is: Does the esp_dmx libray and the ESP32 in general set any timing limitations on the break signal detection?
