When connecting by IrDA I got "Couldn't open PHONET device: No route to host" message. What can be wrong?

Something's wrong with the irda device setup. Try to run:

pkot@bzzzt:~$ echo 115200 > /proc/sys/net/irda/max_baud_rate

and see whether it helps.

Other hints:

  • Check if infrared transmission is still enabled on phone (it is automatically disabled if not used for some time).
  • Check if there are obstacles between IR port on phone and IR port on computer.
  • Check if communication is stuck (use irdadump).
It sometimes happens with my stir4200 USB-IR adapter and I need to unplug and replug it and restart irattach irda0 -s
