Hello,
The Flirc dongle acts like a keyboard, so there's nothing you need to configure on the LibreELEC side - leave Lirc disabled and ignore all the ir-keytable stuff on the LibreELEC infrared remote wiki page.
If you added configurations, changes to autostart, disabled daemons etc please revert all of them or start fresh from scratch. Changes there are most likely to just break things.
Configure the Flirc with the Kodi profile for your remote, using the Flirc configuration tool, and you should be done.
so long,
Hias
thanx for your advice, i will test it tonight.
Does Flirc work parallel to a keybord/mouse or should i disconnect them?
