Remote not work with libreelec

AtomiX · May 19, 2017 at 10:49 PM

Hello to all, I had recently bought a dvb-t receiver with remote included;
The problem is with the remote, is recognized but the system receive no input, the tv tuner works very well.

Code

ir-keytable
Found /sys/class/rc/rc0/ (/dev/input/event11) with:
        Driver dvb_usb_af9035, table rc-it913x-v2
        Supported protocols: nec
        Enabled protocols:
        Name: Avermedia A835B(3835)
        bus: 3, vendor/product: 07ca:3835, version: 0x0200
        Repeat delay = 500 ms, repeat period = 125 ms

I think the issue is related to the empty line of enabled protocols but if i try to change it I receive an error:

Code

kodi:~ # ir-keytable -p nec
/sys/class/rc/rc0//protocols: Invalid argument
Couldn't change the IR protocols

also from dmesg seems IR found it:

Code

I'll attach all logs in this post.

Anyone have any idea to how resolve this issue?

HiassofT: you have any idea why protocol can't be set? There is a user on IRC with same problem.

His ir-keytable -v output:

Hmmm, never seen such a thing before. Which LE version / system / kernel was used, and which USB DVB stick?

"cat /sys/class/rc/rc0/protocols" could give some clues if that's maybe an ir-keytable or kernel issue. Also test if changing protocols directly via sysfs "echo nec > /sys/class/rc/rc0/protocols", then cat again to check, works.

so long,

It was Generic 8.0.2.

Setting protocol directly give same error.

Tuner is TeVii S482: TeVii S482 - LinuxTVWiki

dmesg: TSXB

ir-keytable: QIfh

strace ir-keytable: fgIJ

**HiassofT** · August 15, 2017 at 12:54 PM

Could you test with 8.1.0 and Milhouse? They have newer kernel and ir-keytable versions.

so long,

Hias

**vpeter** · August 15, 2017 at 1:11 PM

Will do if user come back. Thanks for looking.

**HiassofT** · August 15, 2017 at 9:04 PM

Another hint: make sure lirc is disabled in LE settings - that'll probably interfere with that IR receiver. If it was enabled reboot after disabling lirc so the system keytable config is clean.

so long,,
