Troubleshooting steps

This guide provides several troubleshooting steps.

Scenarios

  1. ir-keytable -u returns error: /sys/class/rc/: No such file or directory. No devices found.
  2. No input shows when using dmesg -c

Reset remote

Prior to trying any of the troubleshooting steps below, it is recommended to remove the batteries from the remote for about 1 minute.

After 1 minute, reinsert the batteries. This will “reset” the remote.

Camera test

A digital camera with display (mobile phone, tablet, webcam, DSLR camera,…) can be used to test the IR remote hardware. (1)

  • Point the remote at the camera lens
  • push a remote button

If the IR transmitter LED turns on or flashes in the display when pressing a key on the remote, the hardware is functional.

IMPORTANT: For Bluetooth remote controls, use the green power button to test for an IR signal.

Remove configuration files

IMPORTANT: The meson-ir driver can only load in absence of remote.conf

Remove ALL instances of Meson_IR and AmRemote configuration files from /storage and /flash partition.

To make /flash accessible: 

mount -o remount,rw /flash

OR

  • remove SD/Emmc
  • mount to PC
  • delete remote.conf from root

Reboot / restart / startup the device once all configuration files have been removed.

  • SSH into the device
  • Stop kodi and eventlircd:
systemctl stop kodi
systemctl stop eventlircd
  • Try (2):
ir-keytable -p NEC,RC-5,RC-6,JVC,SONY -t
ir-keytable -u
ir-keytable -u -v

Reset the decoder

Another way is to “reset” the decoder status by removing these files: 

/flash/remote.disable
/storage/.config/remote.disable

Force Meson_IR

Meson-ir also can be forced (3): 

touch /flash/remote.force_meson_ir
touch /storage/.config/remote.force_meson_ir

Notes

  1. Some digital cameras can't be used because they have a filter built-in that removes IR light. Try a different device.
  2. ir-keytable -u starts the IRMP decoder containing most of the known IR protocols.
  3. This should make the presence of (a) remote configuration file(s) irrelevant.

If there is still no output on the console when pushing buttons on the remote, it is likely the IR transmitter is incompatible or the receiver broken.
