Infrared port
 
I am glad to see an infrared port on the N900, but the manual says that it does not support IrDA.

This does not bother me, as I will be using Bluetooth instead, but it then makes me wonder why Nokia bothered to add an IR port at all.

I'm looking forward to using the IR port with Irrecco, but as it is on the long side of the device, it is not ideally placed for this.

CIR, not IrDA. It's for blasting media center electronics, not sending notes to your Palm buddies.

That is why it would have been nicer to have the port on the short edge at the top, as Irrecco has portrait mode support. I did not realise that Nokia were thoughtful enough to have intended the IR port to be used for this.

Great. This what i am looking for.

I'm just glad they could squeeze in the Ir port and deemed it a worthwhile component. I guess only time will tell if location actually yields problems when running Irrecco in portrait mode. I often bounce my signals from my bedroom TV remote off the wall behind me. Works like a charm when pillows/blankets get between me and the TV.

Would much rather have a compass than a CIR port...

Didn't Nokia announce some home automation thing a while back - last year?
With the N900 having IR - it fits into that idea.

Regarding the IR on the side - could still work in portrait, depending on the strength of the IR.

CIR, as in this ?
http://en.wikipedia.org/wiki/Consumer_IR
Never heard of CIR before.
What's the difference between CIR and Irda ?

One's for transferring lines of text between Palm Pilots, the other is for remote controls.

Bluetooth has replaced the need for IrDA, but I used to use it a lot to sync between my ThinkPad using PC Suite.

I still prefer IrDA for such things. Line of sight atleast means nobody is trying to be sneaky ;)

The fact it is CIR is brilliant.

IrDA most often is useless more than about a foot away, in which case you are close enough to press the buttons.

As said above, there would be little point it being IrDA anyway as the N900 has much better technologies for file transfers. My old laptop had IrDA and it was next to useless for transferring to my phone, would lose the connection all the time as it was such a poor signal.

They did, but then lost interest and There picked up the pieces.

The only problem I see is the missing receiver, which kills an use case I find important -- learning.

Like with the resistive/capacitive "debate", there are IrDA ports and then there are good IrDA ports. I could drive my TV up to quite a few meters with the older Palm m130, but then I could barely drive it at a few centimeters using my newer Palm T|X.

True, unless Nokia has the same catalog as Logitech (harmony) - which is probably not the case.

Jason404 2009-10-02 20:18

Re: Infrared port
 
Yes, there is no need for a receiver to 'train' anymore, as there are databases of the required codes all over the place. eg. http://lirc.sourceforge.net/remotes/

I have never had any problem with using IrDA on my ThinkPads and Nokias. It worked very well, but now Bluetooth is more convenient.

I thought CIR and IrDA were just protocols, anyway, and that IrDA could be implemented on the N900 through third party software, if anybody really wanted to?

(Actually, of course, if there is no receiver, you cannot use IrDA, so disregard that last line)

but it would be nice to have your n900 plugged in to your home theater and control it with a remote! I'm not sure about this being CIR only, the chip is capable of fast IrDA and it might be some close to hardware coding needed to make it working as both (which could be the actual reason why nokia left this out for now, most of newer IrDA devices are able to do CIR as well. the used OMAP3430 supports it
http://focus.ti.com/general/docs/wtb...emplateId=6123

and for the records: just 2 days ago I pulled out my old mobile to use its IrDA to transfer a phone-book from an IrDA-only to a bluetooth-only mobilephone

Re: Infrared port
 
If I look at the IR ports on my IrDA devices, I see two IR diodes (or whatever you call them). One must be for receiving, and one for transmitting. I would guess that the N900 only has a blaster for transmitting, just like a TV remote control unit.

Sweet, I see it all now......"starts dreaming"........

I sit on couch, n900 plugged into TV out, Harmony universal on my lap. N900 skype call rings. I switch to PiP (pause: someone updates Skpye on n900 to include video)..I see whos calling onscreen and answer using the Harmony remote over CIR. I Switch PiP to fullscreen and show off the grandkids to the mother in law in Canada while talking about my Christmas list.

........come on amazon.........

this is pretty cool. Too bad extras-devel is down.

Re: Infrared port
 
So is it true that it is not possible to conrol the N900 via infrared?

I had hoped for a setup that would allow me to store movies on the N900, attach the device to the TV, use it like a mobile DVD-player and control it from the couch with a remote control...
