NAME

irsend - basic LIRC program to send infra-red commands

SYNOPSIS

irsend [options] send_once <remote> <code> [code...]
irsend [options] send_start <remote> <code>
irsend [options] send_stop <remote> <code>
irsend [options] list <remote> <code>
irsend [options] set_transmitters <num> [num...]
irsend [options] simulate <button press packet>

DESCRIPTION

Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such as TV boxes, HiFi sets, etc.

irsend supports six sub-commands:

send_once         - send one or more code(s) once
send_start        - start repeating a code.
send_stop         - stop repeating code.
list              - list configured remote items
set_transmitters  - set active transmitters
simulate          - simulate IR event

remote is the name of a remote, as described in the lircd configuration file.

code is the name of a remote control key of remote, as it appears in the lircd.conf configuration file.

num is the transmitter number of the hardware device.

For the list command, remote and/or code can be empty:

list   ""    ""   - list all configured remote names
list remote  ""   - list all codes of remote
list remote code  - list only code of remote

The simulate command only works if it has been explicitly enabled in lircd using the --allow-simulate option. The required button press packet should formatted as a socket broadcast message documented in lircd(8).

OPTIONS

-h --help: Display usage summary.
-v --version: Display version.
-d --device=device: Use given lircd socket [/var/run/lirc/lircd].
-a --address=host[:port]: Connect to lircd at this address.
-# --count=n: Send command n times.

ENVIRONMENT

LIRC_SOCKET_PATH: The lircd socket to connect to, defaults to a hardcoded default value /var/run/lirc/lircd

FILES

/etc/lirc/lircd.conf: Default lircd configuration file. It should contain all the remotes, their infra-red codes and the corresponding timing and waveform details.

DIAGNOSTICS

If lircd is not running (or /var/run/lirc/lircd lacks write permissions) irsend aborts with the following diagnostics:

"irsend: could not connect to socket"
"irsend: Connection refused" (or "Permission denied").

EXAMPLES

irsend LIST DenonTuner ""
irsend SEND_ONCE  DenonTuner PROG-SCAN
irsend SEND_ONCE  OnkyoAmpli VOL-UP VOL-UP VOL-UP VOL-UP
irsend SEND_START OnkyoAmpli VOL-DOWN ; sleep 3
irsend SEND_STOP  OnkyoAmpli VOL-DOWN
irsend SET_TRANSMITTERS 1
irsend SET_TRANSMITTERS 1 3 4
irsend SIMULATE "0000000000000476 00 OK TECHNISAT_ST3004S"

DRIVER LOADING

Drivers are loaded dynamically. The directory used for this is determined by (falling priority):

The environment variable LIRC_PLUGINDIR.
The 'plugindir' entry in the [lircd] section of the lirc_options.conf file.
A hardcoded default (/usr/lib/x86_64-linux-gnu/lirc/plugins).
