I am having problems getting a remote to work

spotless · January 28, 2021 at 1:18 PM

First: Thank you all for this great project

The version is Nightly-20210119-c4186be

I am using this guide Infra-Red Remotes - LibreELEC.wiki and an ssh into a terminal

I edited nano /storage/.config/rc_maps.cfg

and placed this line at the bottom

* rc-leadtek-y04g0051 leadtek_y04g0051.toml

Then I cp /usr/lib/udev/rc_keymaps/leadtek_y04g0051.toml /storage/.config/rc_keymaps/leadtek_y04g0051.toml

so that I could change the remote to include the "back" command

I enable the changes with

ir-keytable -c -w /storage/.config/rc_keymaps/leadtek_y04g0051.toml

The remote works great until I reboot

Then it does nothing until I

ir-keytable -c -w /storage/.config/rc_keymaps/leadtek_y04g0051.toml again

I noticed this in the wiki

"The embedded files can be overridden at boot time by creating

/storage/.config/lircd.conf and

/storage/.config/lirc_options.conf

with needed changes."

What are they for? Is this what I need to change?

Mine are empty.

Any help would be appreciated

Try to do what's described here: RE: LibreELEC 9.2.6 Raspberry 4 and IrDA Dongle

( a solution should be to use ir-keytable -a .... )

In LE 9.80 Nightly builds there're newer drivers so the mapping files have a bit different structure ( and .toml extension) but in general it's the same (also the older files without .toml extension are supported as well).

So now I have done this

1) systemctl stop kodi

2) systemctl stop eventlircd

3) I edited nano /storage/.config/rc_maps.cfg

and placed this line at the bottom

* rc-leadtek-y04g0051 /storage/.config/rc_keymaps/leadtek_y04g0051.toml

4) ir-keytable -c -w /storage/.config/rc_keymaps/leadtek_y04g0051.toml

5) ir-keytable -a /storage/.config/rc_maps.cfg -s rc0

6) test with ir-keytable -t -s rc0

All looks good

7) systemctl start eventlircd

systemctl start kodi

9) reboot

result remote not working

Re-read guide Infra-Red Remotes - LibreELEC.wiki

and tried

1) systemctl stop kodi

2) systemctl stop eventlircd

3) Thought this was ok

4) not done

5) ir-keytable -a /storage/.config/rc_maps.cfg

Note I did not get any output as in the guide ( below) with this rc_maps.cfg

A clue

back to 3)

3) I edited nano /storage/.config/rc_maps.cfg

# driver table file

#

* rc-leadtek-y04g0051 /storage/.config/rc_keymaps/leadtek_y04g0051.toml

first change was to

sunxi-ir rc-leadtek-y04g0051 /storage/.config/rc_keymaps/leadtek_y04g0051.toml

still did not work. So changed to

sunxi-ir * /storage/.config/rc_keymaps/leadtek_y04g0051.toml

Worked so my problem is in the table name

LibreELEC:~ # ir-keytable -a /storage/.config/rc_maps.cfg

Old keytable cleared

Wrote 50 keycode(s) to driver

Protocols changed to nec

6) test with ir-keytable -t -s rc0

All looks good

7) systemctl start eventlircd

systemctl start kodi

9) reboot

Remote Works now.

On a side note

I noticed Default keymap: rc-empty could this be a problem in the future?

# ir-keytable

Found /sys/class/rc/rc0/ with:

Name: sunxi-ir

Driver: sunxi-ir

Default keymap: rc-empty

Input device: /dev/input/event0

LIRC device: /dev/lirc0

Attached BPF protocols:

Supported kernel protocols: lirc rc-5 rc-5-sz jvc sony nec sanyo mce_kbd rc-6 sharp xmp imon rc-mm

Enabled kernel protocols: lirc nec

bus: 25, vendor/product: 0001:0001, version: 0x0100

Repeat delay = 500 ms, repeat period = 125 ms

Thanks for your reply ghtester

It sent me into the right direction to find the solution

No problem, I'm glad I could help.

FYI there's also a fresh how-to made by Skripo here: Kodi, Harmony, and Raspberry PI 4 with IR sensor newb guide

Regarding to rc-empty - I don't know, perhaps the -c cleared the default keymap. I have never used that parameter so I don't know details.

Or it depends on .toml file structure which is maybe missing some keywords, I really don't know.

I think the Default keymap is assigned by kernel driver when the IR device is detected.

Probably it does not matter if there's rc-empty when everything is working fine. And when it stops working, you know what to check / how to make it working again...
