If i understand correctly, you want to send a command for the second time only after a certain time, right? Couldn't you also use the puls command for it? if you set puls the signal could be 500ms on, 500ms off, 500ms on, etc...
When it is not useful to send the command multiple times you could always use the release event.
The delay option looks to me as if the command is ran after 500 ms when the event is triggered (even for the first time).
I can confirm at least the site license and some basic commands work with the iTach Flex. I haven't had an opportunity to test it thoroughly but it should be OK. The module type I added to the project was "iTach IP2IR"
I think that is essentialy what is requested in this topic. Quite a few people have voted for it and it is planned. Maybe someone from iRidium Support can give an estimate of a probable completion date.
