HerePro V2 LUA LEDs not working

Hello all,

I’m currently trying to control the LEDs of the HerePro V2 using a LUA script.
I set these parameter inside the HerePro V2: GPS_TYPE = 1 and NTF_LED_OVERIDE = 1. I’m not sure if there are other parameters that should be set as well.
I then tried to upload this script: https://github.com/ArduPilot/ardupilot/blob/master/libraries/AP_HAL_ChibiOS/hwdef/HerePro/scripts/hereproled.lua.
After uploading, the LEDs still behave the same as before the upload (so the script does not seem to work).

What am I doing wrong?

Best regards, Max
