Infrared reception..??


Does anyone know how to use infrared reception in linux?
The goal is to synchronize my nokia with kde-pim.

looks like there's a bunch of how-to's and related info on this:

and there's others on getting IrDA to work (needed as a basis), I got links by sticking "infrared phone linux" into google.

that should get you started, at least enough to start asking more questions about it. I haven't done it or know much about it myself

more IR struggles

I too am attempting to get an IR connection from linux to phone/pda. Let's compare notes; I've made some progress but no connection yet.

The hardware: old Sony F-150 laptop to Nokia 3650 phone. The linux install: Mandrake 9.0 distro install, followed by kernel and other minor updates.

Stage 1 would seem to be: what is the IR controller and its configuration? I downloaded the irdautils package, and it (mostly) built without incident. findchip says:
# /usr/sbin/findchip -v
Found SMC FDC37N958FR Controller at 0x370, DevID=0x01, Rev. 1
SIR Base 0x3e8, FIR Base 0x140
IRQ = 10, DMA = 1
Enabled: yes, Suspended: no
UART compatible: yes
Half duplex delay = 3 us

Now there's a kenel module named smc-ircc, but when I try to load it:
# modprobe smc-ircc
/lib/modules/2.4.22/kernel/drivers/net/irda/smc-ircc.o: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg
modprobe: insmod /lib/modules/2.4.22/kernel/drivers/net/irda/smc-ircc.o failed
modprobe: insmod smc-ircc failed

Finally, I note that the hardware auto-detect during my Mandrake install wrote the following:
# cat /etc/sysconfig/irda
... bit it didn't call for the loading of any IR modules at boot time.

So here's my current questions and thinking:
1) I'm presuming that I need a hardware-specific driver module as well as the irda module loaded? Do some more searching to verify this. I've read the IR-HOWTO, it's not too helpful with "big picture" questions like this.
2) Go read the code for the smc-ircc module; find out where it gets its configuration information.
3) Are there intermediate points of success I can try for? What are they?

Finally, where are you in this process? What have you tried? What works and what doesn't?

regards, John

Uhmmmm, didn't quite get as far as you did, totally newbie on hardware, and drivers on linux.
I'll try it as soon as possible.
