How to read IRDA data from cell phones ?

[flotulopex]

Hello,

I'm wondering if anyone already tried to use IrDA "OBEX" (OBject EXchange protocol) or "Point And Shoot" to send some data from a cellphone to a PIC.

I could find some interresting stuff, especially these documents:

http://www.irda.org/associations/249...l%20Basics.pdf.
http://netwinder.osuosl.org/pub/netw...oot%20v1p0.pdf

Amongst all IR protocols, OBEX and "Point And Shoot" look to be the ones to use for data transfer in this situation.

It may appear simple in the docs, but simple doesn't always mean easy.

So if anyone used this before and could share some info, it would be welcome.

NB: my goal is to find a way to update a PIC's program without having to connect it via wires nor using a particular programmer (thus my idea: use a cellphone).
