Interpretation of ACK_TIMER

[eldoMS]

Hello,

Is it correct that a 0x0000 as an ACK_TIMER response indicates a "come back immediately for the requested and queued data"?

Yes, that is correct.

I have to ask though, if you are ready immediately then why ACK_TIMER?

[ericthegeek]

If you need a bit more time than 176us, but don't need the 100ms minimum value allowed in ACK_TIMER. The shortest possible RDM packet is around 1.3ms, so by the time the responder can send you the GET QUEUED_MESSAGE you'll have the data it requested.

Hi Eric/Scott,

Yes, indeed this can serve quick turn-arounds, even a little bit more than 1.3 ms, depending on the application the ACK_TIMER reply itself (also 1.3 ms) as well as the max delay to response (2 ms) could be added together, of course depending very much on application.
