I'm trying to get irsend to control an IR diod connected to GPIO 4 but for some reason I cannot get it to work. irsend doesn't recognize the controller I've specified.

When I do irsend list "" "" I get nothing back.

pi@magpi:~ $ irsend list "" ""
pi@magpi:~ $ 

I've followed this tutorial to set up Lirc http://alexba.in/blog/2013/01/06/setting-up-lirc-on-the-raspberrypi/

These are my configuration files:


# /etc/modules: kernel modules to load at boot time.
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

lirc_rpi gpio_out_pin=4




# this config file was automatically generated
# using lirc-0.6.5(sir) on Sat Mar 30 19:11:50 2002
# contributed by
# brand:                       Grundig
# model no. of remote control: TP-750C (TelePilot 750C)
# devices being controlled by this remote: ST 55-908 DOLBY

# /etc/lirc/hardware.conf
# Arguments which will be used when launching lircd

#Don't start lircmd even if there seems to be a good config file

#Don't start irexec, even if a good config file seems to exist.

#Try to load appropriate kernel modules

# Run "lircd --driver=help" for a list of supported drivers.

# usually /dev/lirc0 is the correct setting for systems using udev

# Default configuration files for your hardware if any

The tips I've already have led me to look at the following things:

pi@magpi:~ $ ls -la /dev/lirc*
crw-rw---- 1 root video 245, 0 Jan 17 09:52 /dev/lirc0
lrwxrwxrwx 1 root root      21 Jan 17 09:52 /dev/lircd -> ../var/run/lirc/lircd
pi@magpi:~ $ 

and this (the little cirle/ball to the left of "lirc.service" is green, I assume that is good. But the "unexpected end of file" I assume is not so good, but I don't understand what file is unexpectedly ending nor how to fix it)

pi@magpi:~ $ sudo /etc/init.d/lirc status

pi@magpi:~ $ 

and this

pi@magpi:~ $ dmesg | grep lirc [ 5.376466] lirc_dev: IR Remote Control driver registered, major 245 [ 6.672805] lirc_rpi: module is from the staging directory, the quality is unknown, you have been warned.

and different version things

pi@magpi:~ $ uname -a
Linux magpi 4.1.18-v7+ #846 SMP Thu Feb 25 14:22:53 GMT 2016 armv7l GNU/Linux

pi@magpi:~ $ lircd --version
lircd 0.9.0-pre1
pi@magpi:~ $ 

Does anyone have any idea why irsend list can't see my remote? Does it have anything to do with the "unexpected end of file" and if so, what does that mean?

Thanks very much for reading!

I wrote some initial tricks in http://martinho.comuf.com.

But be attention on "UNCONFIGURED" lines in config files.

As I wrote there some diagnostics tricks and that You have to remove all lines with word "UNCONFIGURED" in /etc/init.d/lirc

I don´t know why but a script look for that word even as comment.

Make backup of files before edit and dont´t forget to reboot after changes.

I tried the same command and it responded:
pi@raspbcasa:~ $ irsend list "" ""
irsend: TV_raw
irsend: aquario_raw
irsend: VCR_raw
irsend: TVIR
irsend: tv_philips_code
irsend: MXT9800L_codes
irsend: VCR_LG_code
irsend: aquario_codes
irsend: LG_VCR_Remote

---I´m using a Raspberry PI3---

If you continue in trouble with the command [irsend list "" ""] let me know.

    Unfortunately your link martinho.comuf.com is dead. BTW: I created an extensive tutorial on stackexchange on how I managed to remote control my TV using only a Raspberry Pi and an old Infrared diode from an old remote control. – Besi Aug 9 '17 at 9:41

    Sorry, The link is ok now. Very good your tutorial and troubleshooting. You can continue and send commands using web program in raspberry access by phone or general browser. It's very useful. – Jmart Aug 10 '17 at 1:40
