Sending the AVIONICS_MASTER_1_SET event does not toggle the avionics when starting dark and cold with the default DR400.
However the event is able to toggle it off (and then back on) if and only if it was first activated from the cockpit. It seems that triggering the event acts like a necessary condition, but not a sufficient one.
I noticed that the BUS CONNECTION ON:2 simvar happens to be set to 1 or 0 when the button is clicked on/off in the cockpit, but NOT when the event is sent from SimConnect. Its value remains untouched, so the avionics are not actually turned on.
Some other observations :
- Setting a keyboard mapping does not work either.
- MASTER_2_SET and MASTER_SET do not work either.
- Everything works as intended with the C172 (events, keyboard mapping, ...)
Thanks for any help !
