Hi @Divy, thanks for the update, and glad to hear you managed to get things working!
The NTF_LED_OVERRIDE parameter allows changing from the autopilot’s standard notification functionality to instead being controlled by MAVLink or Lua scripts - I presume that’s what was used?
There are already some LED-related example scripts, but if your use-case isn’t well-covered by them then it would indeed be helpful if you can share your process, so others who want to do something similar have a basis to do so
