Problem description:

I ordered these parts (from adafruit) and tried setting up the sensor/remote with the instructions on the wiki.

It tells me to run the following commands via SSH:

Terminal

xbian@xbian:~# sudo su
root@xbian:~# /etc/init.d/lirc stop
root@xbian:~# mode2

And after I run the "mode2" command, nothing happens, and I either wait a long time or reconnect via SSH to do anything. I pressed every button on my remote at least twice, around 5 inches in front of the sensor.

I've tried different things, such as this post related to Logitech Harmony issues, but still get nothing when I try to run the mode2 command.

I tried running (from this thread):

Terminal

sudo modprobe lirc_rpi
sudo kill $(pidof lircd)
sudo mode2 -d /dev/lirc0

but still get no output after the mode2 command.

I ran these commands:

Terminal

sudo lsmod
sudo modprobe lirc_rpi
sudo lsmod

and one of the results was:

Terminal

Module Size Used by
lirc_rpi 4756 3
lirc_dev 6580 1 lirc_rpi

so I think that means the sensor is being detected.

I've changed the wires connecting to the IR sensor several times, making sure they are in the correct place. I used a camera to see if the IR remote was working (and it appears so). I am wondering if my sensor is "dead" or if I am doing something wrong (most likely). Is there a way I can know if the IR sensor is working or not?
