Hi Jean
The definitive Ultra spec is part of IrMC, not IrWW. The IrWW version is
specific to Shimokura-san's watches.
Speaking as one of the authors, though, please don't base a new
implementation on Ultra unless it's specifically to talk to watches. Ultra
was a solution to a problem that didn't really exist, we just didn't know
it. At the time, we hadn't been exposed to IrDA Lite's ability to cut the
main stack down to really small model device sized byte counts. (Ultra
predates Dave Suvak's IrDA Lite by two meetings.) If we had, we'd've never
written Ultra.

If you want to keep the complexity down on the microcontroller
side, use Ultra (the spec is available inside the IrWW package). We
are currently using bare Ultra, and we plan to go Obex over Ultra.
Advantages :
o much, much, much simpler to implement
o More robust than full IrDA
o faster than full IrDA
