This information applies to following devices:

• Odroid N2
• Odroid N2+
• Odroid C4
• Odroid HC4
• Amlogic devices with CoreELEC BL301 blob injected

CoreELEC comes with a list of predefined IR power codes. There are codes are for:

• Hardkernel
• Minix
• Beelink
• Khadas
• MCE
• …

This option can be accessed by navigating to:

• Settings
• CoreELEC
• Hardware
• IR Remote Power Code

If there is no matching IR power code predefined, this option can be used to find the devices unique IR power code.

Since CoreELEC uses Meson_IR by default, it is possible to scan a device for the IR remote wakeup code and apply this code to the file config.ini

IMPORTANT: If a Meson_IR remote is used with the device, remove or rename any remote.conf located in:

/flash/

and, or:

/storage/.config/

After a reboot the meson-ir device will be active.

• SSH into device and stop the Kodi and eventlircd services:

systemctl stop kodi
systemctl stop eventlircd

• run ir-keytable with option -u

ir-keytable -u

• press the desired button for wake up on the IR Remote

If the decoded protocol is implemented a code like will show:

Received IRMP code: remotewakeup='0xbf40fe01', decode_type='0x0', remotewakeupmask='0xffffffff'

• Enter these values in the config.ini file.

On the next suspend/power off, the device should now be able to wake up by pressing the preferred button with the previously scanned IR code.

Support for a remote wakeup user file was implemented into CoreELEC February 2021

Naming convention:

(name).remotewakeup 
eq: mytvbox.remotewakeup

Custom wakeup code file syntax:

remotewakeup='0xaabbffff'
decode_type='0x0'
remotewakeupmask='0xaabbffff'

Location: /storage/.config/

touch /storage/.config/H96ProPlus.remotewakeup
vi /storage/.config/H96ProPlus.remotewakeup

• insert

remotewakeup='0xbf40fe01'
decode_type='0x0'
remotewakeupmask='0xffffffff'

• [ESC] :wq [ENTER]
• reboot

After reboot the IR wakeup code should be available in CoreELEC settings.

When receiving:

/sys/class/rc/: No such file or Directory

• force meson-ir modus:

touch /storage/.config/remote.force_meson_ir
reboot now

After reboot the above command should work, and the file remote.force_meson_ir can be deleted to re-enable the meson-ir protocol.

If the decoded protocol is not implemented a message similar to this one will appear:

Received IRMP code: scancode='0x00251001', IRMP protocol = 7, decode_type is undefined!

In this case an implementation/code mapping for u-boot would be needed.

If there is no message, the IR pulses need to be debugged to detect the correct IR protocol:

echo 2 > /sys/module/rc_core/parameters/debug

The received IR pulses will be printed to the kernel console and can be read by entering

dmesg

config.ini can be edited in 2 different ways:

The easiest way to edit the config.ini file is to insert the USB Flash Drive or (μ)SD card with CoreELEC into a Personal Computer and edit the values remotewakeup, decode_type and remotewakeupmask with a unix compatible file editor.

SSH root@ip_address

• make /flash writable

mount -o rw,remount /flash

• edit config.ini

vi /flash/config.ini

• enter:

sync && reboot
