I'm trying to configure a Stream Deck button to hold down a Primer button until released. I've tried setting up a Long Press at 100 ms, but all that happens is the button goes up and down repeatedly. Same thing happens on every other method I've tried.

That is not possible in the SD actions alone, you need scripts for key down and key up - and the correct method. This is not easy to do, because the SimConnect simulator interface doesn't allow events "being held", they are always "momentary". What button is that exactly?

"long press" means that the button assignment fires after a period of time. Nothing else to it.

It is the primer button in the Cessna 400 TT.

OK, I've looked into that one. Keeping this button pressed is only possible with the mouse, not with outside controls.

To operate this button it is necessary to manipulate the O: vars that are assigned to it, and that has never been possible - until the latest SU of MSFS 2024. The option to access O: and I: variables will be available in version 4.59 of AAO.

If you want, send an email with your proof of purchase to the support address (on the last page of the manual). Then you can have the 4.59 to try it out.

For completeness sakes, here are the scripts:
Key down:
1 (>O:ENGINE:ENGINE_LEVER_PRIMER:_Interaction_Is_Locked, Number) 1 (>B:ENGINE_PRIMER_Toggle)

Key Up:
0 (>O:ENGINE:ENGINE_LEVER_PRIMER:_Interaction_Is_Locked, Number) 1 (>B:ENGINE_PRIMER_Neutral)

Remember that they only work in AAO 4.59 onwards, which is still being tested.
