How to read IRDA data from cell phones ?

[serandre]

Is there any code to get/send data from a cell phone (Nokia 6600) via a IR link ?

Thanks

Not off the top of my head, but have a look at the link below, there are many papers written on the subject

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://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).

What PIC are you planning on using? How are you planning on getting the update in to your cellphone? MOST phones (including Nokia) don't like to receive file extensions they don't know about (for security) so generally receive them and hide them, or reject them. You COULD make a MASTER programmer which uses IrDA or RF or whatever, and then you won't have to worry about the complexities of having different chipsets trying to chat with eachother.

ALSO remember that if YOU can use a cellphone to upgrade a PIC using "point and shoot" (I assume you are looking for some kind of commercial application) then I can use a cellphone to rob your information, AND I can use a cellphone to sabotage YOUR product.

I'm not making money with my gadgets; I leave this up to far more qualified people than me

Security is not an issue since my circuit is an ir-remote (only simple-minded people are willing to hack a TV or DVD remote signal, no?)

The remote has to "learn" the ir pattern from an original remote. Instead of having to learn it that way, I thought it would be interresting, if you'd have lost the original remote, still to be able to send the original pattern to my remote.

Grabbing around the web, I could find some interresting infos on this excellent site http://www.lirc.org/ with a lot of details about the different ir patterns used in today's remotes. I could use some of them and transmit them via a mobilephone to my remote.

I don't need any transmission protocol; I would like the phone to send the ir-pattern like a remote would do. I found some softwares and will test them shortly.

Btw, I'm using a 16F88.

Actually sounds like a good project to me Roger. Let us know how you get on. How do you propose to write the data to the PIC once the IR data has been received?
