TechnoTrend TVStick CT2-4400: RC-5 protocol disabled

swimm3r · February 24, 2019 at 10:59 AM

Hello all,

I am using TechnoTrend TVStick CT2-4400 as DVB-C tuner, but I cant use the TT Remote Control because rc-5 protocol is disabled. Can anyone help me to enable the rc-5 protocol for ir-keytable?

Thank you very much.

This looks odd. Do you have any .config/lircd.conf or .config/rc_maps.cfg files on your box or some ir-keytable commands in autostart.sh and/or enabled one of the optional DVB driver sets?

Also: which LibreELEC version are you using and on which platform (it looks like you are using RPi)?

Please post a full journal output journalctl -a | paste

so long,

Hello,

http://ix.io/1buk

I am using RPi 3, with LE 8.2.5

swimm3r · February 24, 2019 at 11:50 AM

I use .config/rc_maps.cfg with the following content:

* rc-tt-1500 tt_1500

Thank you for your time and support.

**HiassofT** · February 24, 2019 at 12:01 PM

Please update to LibreELEC 9.0, 8.2.5 is no longer supported.

The logs showed that you also enabled the RPi GPIO IR receiver - better disable that.

so long,

Hias

I will try to update to LibreELEC 9.0 and I will return with status update.

Thank you very much for your time and support.

Best regards,

HiassofT : You are right, It is all OK with LibreELEC 9.0

Thank you very much.
