Just did this for a BT remote from a "Nvidia Shield TV" (from around ~2015) and it works as expected with latest LibreELEC.

It seems like multiple Android-box remotes use KEY_SELECT for the "ok" button while Kodi expects "Enter" for selecting things.

Maybe LibreELEC should add a default config for BT remotes so c0041 gets mapped "enter"?

Hi,

Wanted to report a incorrect configuration for a Xiaomi remote and a fix for it. Documenting this fairly detailed to assist anyone else that may have a similar issue.

This is a guide on how to remap this invalid keycode. See "70-local-keyboard.hwdb" part for what should be added to libreelec's defaults.

# cat /proc/bus/input/devices

Default mapping of the button.

# systemctl stop kodi

# /storage/.kodi/addons/virtual.system-tools/bin/evtest

....

Event: time 1668034708.559812, -------------- SYN_REPORT ------------

Event: time 1668034708.717304, type 4 (EV_MSC), code 4 (MSC_SCAN), value c0041

Event: time 1668034708.717304, type 1 (EV_KEY), code 28 (KEY_SELECT), value 0

Event: time 1668034708.717304, -------------- SYN_REPORT ------------

But to work with kodi this needs to be mapped to KEY_ENTER and it defaults to KEY_SELECT.

# udevadm test /devices/virtual/misc/uhid/0005:2717:32B9.0003/input/input8 2>&1 | grep ^MODALIAS

MODALIAS=input:b0005v2717p32B9e4A4C-e0,1,4,k72,73,74,80,8C,90,9B,9C,9E,9F,AC,AD,161,189,18F,190,191,244,246,ram4,lsfw

Create, or update, the file /storage/.config/hwdb.d/70-local-keyboard.hwdb with the following entry. Device-identifier (red) you get from udevadm and the keycode (green) comes from evtest.

evdev:input:b0005v2717p32B9e4A4C*

KEYBOARD_KEY_c0041=enter

Reload udev rules, or just reboot.

# udevadm hwdb --update
# udevadm trigger -s input

and now i got a working Xiaomi remote.
