Raspberry Pi で 赤外線リモコン（LIRC を送信）#2

LIRCの受信動作までは確認できましたが、送信処理がうまく行きません。

下記のような記事を見つけましたが、bullseye には hardware.conf は不要なのかもしれません。

　※ 最新の Raspbian Stretch OSは /etc/lirc/hardware.confファイルが存在しません。

　hardware.confファイルの代わりに /etc/lirc/lirc_options.confファイルを編集します。

lircd.conf を作成

$ irrecord -n -d /dev/lirc1 lircd.conf

This program will record the signals from your remote control
and create a config file for lircd.

A proper config file for lircd is maybe the most vital part of this
package, so you should invest some time to create a working config
file. Although I put a good deal of effort in this program it is often
not possible to automatically recognize all features of a remote
control. Often short-comings of the receiver hardware make it nearly
impossible. If you have problems to create a config file READ THE
DOCUMENTATION at https://sf.net/p/lirc-remotes/wiki

If there already is a remote control of the same brand available at
http://sf.net/p/lirc-remotes you might want to try using such a
remote as a template. The config files already contains all
parameters of the protocol used by remotes of a certain brand and
knowing these parameters makes the job of this program much
easier. There are also template files for the most common protocols
available. Templates can be downloaded using irdb-get(1). You use a
template file by providing the path of the file as a command line
parameter.

Please take the time to finish the file as described in
https://sourceforge.net/p/lirc-remotes/wiki/Checklist/ an send it
to  <lirc@bartelmus.de> so it can be made available to others.

Press RETURN to continue.

Checking for ambient light  creating too much disturbances.
Please don't press any buttons, just wait a few seconds...

No significant noise (received 0 bytes)

Enter name of remote (only ascii, no spaces) :TV

Using TV.lircd.conf as output filename

Now start pressing buttons on your remote control.

It is very important that you press many different buttons randomly
and hold them down for approximately one second. Each button should
generate at least one dot but never more than ten dots of output.
Don't stop pressing buttons until two lines of dots (2x80) have
been generated.

Press RETURN now to start recording.
