Hi. I need to implement a one-directional transmission over IR. The distance between the Palm and the IR Sender is too big to establish a connection (the Palm IR led is too weak for this distance). On the PalmDev website, it says that the Palm OS 5 irDA protocol stack allows connectionless data transmissions using IR. But looking at the OS 5 API, I can't find any function allowing me to send or receive data in a no-connection mode. All suggestions appreciated !
The only connectionless IrDA protocol I'm aware of is 'ULTRA', and at least according to the OS5 docs, it isn't supported (referring to page 1305, 2nd paragraph of the OS5 ref manual). Maybe the docs are wrong, though :-/
The other option is to use TST frames from within IrLib - has some overhead, and is limited to the NDM baud of 9600, and the payload/time is limited as well. see "IrTestReq" in the ref manual for more ideas.

PS there are other ways to send your own IR packets - through the serial API, for example - but it's not reliable across all OS5 devices. Search the comm-dev-forum archives on "Raw IR" for more info.
