You’re welcome! You’re not off topic at all. I admit I have not tried these yet (I could report back in a week or so, when I have time to experiment with these myself).
A quick search online revealed to me that:
- Boardlink products do not currently support the “long press” (or “hold”) function (see reddit)
- There is no concept of “hold” in IR, it’s just multiple blocks sent over a period of time
- As such, the common suggestion is to write scripts that send the instruction N times over M seconds, see e.g. here
I’ll try it out at some point and let you know
