EDIT: This is the output of lsmod when I remove the lirc lines from /etc/modules, /etc/rc.local, and /etc/modprobe.d/ir-remote.conf:

LIRC remote control won't send (irsend: hardware does not support sending)

I'm trying to build a TV remote control using Raspberry Pi, and I get the following error when I try to send a command:

pi@raspberrypi:~$ irsend SEND_ONCE Samsung_BN59-00937A KEY_POWER irsend: command failed: SEND_ONCE Samsung_BN59-00937A KEY_POWER irsend: hardware does not support sending

I've built an IR circuit, which works fine when I test it using a simple blinking script:

#!/usr/bin/python import RPi.GPIO as GPIO import time print "Starting blink test.." GPIO.setwarnings(True) GPIO.setmode(GPIO.BCM) GPIO.setup(17, GPIO.OUT) while True: GPIO.output(17, True) time.sleep(1) GPIO.output(17, False) time.sleep(1)

When I run this I can see the IR LED blinking using a camera LCD viewfinder. The circuit is wired according to this tutorial.

I set up LIRC following [this tutorial](http://alexba.in/blog/2013/01/06/setting-up-lirc-on-the-raspberrypi/].

My /etc/modules has these two lines in it:

lirc_dev lirc_rpi gpio_in_pin=18 gpio_out_pin=17

My /boot/config.txt has this line in it:

dtoverlay=lirc-rpi,gpio_in_pin=18,gpio_out_pin=17

My /etc/lirc/hardware.conf looks like this:

# /etc/lirc/hardware.conf # # Arguments which will be used when launching lircd LIRCD_ARGS="--uinput" #Don't start lircmd even if there seems to be a good config file #START_LIRCMD=false #Don't start irexec, even if a good config file seems to exist. #START_IREXEC=false #Try to load appropriate kernel modules LOAD_MODULES=true # Run "lircd --driver=help" for a list of supported drivers. DRIVER="default" # usually /dev/lirc0 is the correct setting for systems using udev DEVICE="/dev/lirc0" MODULES="lirc_rpi" # Default configuration files for your hardware if any LIRCD_CONF="" LIRCMD_CONF=""

My /etc/rc.local has this line in it:

modprobe lirc_rpi gpio_in_pin=18 gpio_out_pins=17

I also tried following the suggested answer from this question and added the file

/etc/modprobe.d/ir-remote.conf

with this line in it:

options lirc_rpi gpio_in_pin=18 gpio_out_pin=17

But I still get the same error with irsend. Please could somebody help me fix this? Thank you.
