Trying to setup a custom key map to use LIRC.Send(command)

Help and Support Vero 4K / Vero 4K +

I have a bluetooth remote that I’ve been using with my Vero4K almost a year now.

It has Vol+ and Vol- buttons that, unfortunately, are not directly re-learnable.

So I’m trying to modify my keymap file:

/home/osmc/.kodi/userdata/keymap/gen.xml

<keymap>
            <global>
                    <keyboard>
                            <key id="61654">contextmenu</key>
                            <key id="61620">stop</key>
                            <key id="61572">pageup</key>
                            <key id="61573">pagedown</key>
                            <key id="61626">stepforward</key>
                            <key id="61627">stepback</key>
                            <key id="61637">fastforward</key>
                            <key id="61636">rewind</key>
                            <key id="61630">showsubtitles</key>
                            <key id="61675">osd</key>
                            <key id="61623">LIRC.Send(SEND_ONCE Yamaha_RAV337 KEY_MUTE)</key>
                            <key id="61625">LIRC.Send(SEND_ONCE Yamaha_RAV337 KEY_VOLUMEUP)</key>
                            <key id="61624">LIRC.Send(SEND_ONCE Yamaha_RAV337 KEY_VOLUMEDOWN)</key>
                </keyboard>
        </global>
</keymap>

…so that when kodi receives the key press, it will send the IR single to my AV Receiver to up/down the value.

I have modified the file: /etc/lirc/lircd.conf to include my Yamaha_RAV337 device:

begin remote

    ZONE2_MUTE               0x0000000000023DC
  end codes
end remote

…rebooted, and turned on debugging.

I get the following in my kodi.out:

22:27:40.285 T:4078092880   DEBUG: -------------Keyboard keyevent----------------

But my receiver isn’t receiving a signal.

I tried a manual test via:

irsend -d /dev/lirc0 SEND_ONCE Yamaha_RAV337 KEY_VOLUMEUP

but I get errors:

irsend: could not connect to socket
irsend: Connection refused

Anyone have any ideas?

irsend -d /dev/lirc0 SEND_ONCE Yamaha_RAV337 KEY_VOLUMEUP

On what device are you trying this?

It has Vol+ and Vol- buttons that, unfortunately, are not directly re-learnable.

Any BT device can be remapped via eventlircd.

Device: Vero4k

When running irsend I assume you are trying to use the built in IR transmitter.

See Vero 4K + IR Queries

Yes, the internal IRblaster. So based on the link, you’re saying that the internal IRblaster isn’t usable on the Vero4k?

I’ve tried it two ways:

Via kodi key mapping:
LIRC.Send(SEND_ONCE Yamaha_RAV337 KEY_VOLUMEDOWN)

and manually via:
irsend -d /dev/lirc0 SEND_ONCE Yamaha_RAV337 KEY_VOLUMEUP

…neither worked.

So just a follow-up:

Kodi uses the irsend binary, correct? Since I have everything configured via kodi, if a future release contains a Vero4K compatible irsend binary, can I assume it should just start working then?

THANKS!

Nothing in OSMC presently uses the IR blaster at all.
There’s been some discussion about running an ir-send service in the past.

The problem isn’t the binary, but rather that ir-send isn’t able to communicate with the IR blaster via a compatible interface.

In the future, given enough demand, we’ll either:

  • add meson_irblaster module, which will provide an ioctl like interface for blasting. This will be ab it cumbersome but we expect those who plan to send IR signals will be happy to write a script
  • integrate ir-send support by providing a compatible hardware kernel module
