File Transfer via irDA
 
How do we transfer files via irDA?

Seems we only have options:
Send via Bluetooth
Share via service(which is fMMS)
Send via E-mail

Is there an application we need to install to enable file transfer via irDA?

N900 does not have IrDA. The IR port can only send, not receive.
File transfers are not possible.

What???

I checked our manual (page 15)
Quote:
None of the pre-installed applications of your device use the infrared port, but it enables the development of third party applications requiring an infrared port. The infrared port is not IrDA compatible.
So, do we have any application for the IrDA?

Irreco is a remote control software which uses IrDA.
By the way, is it possible to build an app to send files over IrDA, not to receive?

Again. The IR port of the N900 IS NOT AN IrDA PORT.
IrDA requires two way communication, as do file transfers in any direction.
The only thing that can be done with N900's IR port is stuff like IrReCo...

@kenraali The problem is that we only have the ir emitter and not a receiver.

This means, in a developer perspective:
1) we cant comply the irda file transfer standard (because we need the receiver too), so you need to develop a custom irda protocol, from the emitter part (n900) and the receiver part (the PC? what device are you trying to communicate with? you need to develop the custom receiver software for each one)

2) you can't verify the data that you are sending. If you are sending a 2mb file, you really cant know if the file gone corrupt in the transfer operation.

I can't imagine why Nokia would put the Ir emitter and not a receiver. What could we use it for? Any advantage?

cheaper for them. And almost noone uses IrDA anymore.

Cheaper for them than what?

A real IrDA compliant IR port with emitter and receiver.
The IR diode they used only costs them a few cents.
