Configuring IR Remote with Technotrend TT-4600

Help and Support Raspberry Pi
1

Hello,

I have just installed OSMC on Raspberry Pi 3 B and attached a DVB-S2 tuner to it (Technotrend TT-4600) and it worked out of the box without any driver issues but the remote does not work and I know it has no defects because it works under windows. Is there a tutorial to follow about configuring the IR Remote that came with the tuner itself.
I don’t have any problem to read, learn, and try before I post for help. I tried to find something useful to read about using “irrecord” but without any success.
One thing to mention is when I use “ir-keytable -t” there is a response and I know all the scan-codes for every button from previous trials to configure it under libreelec.

Best Regards

So if the IR reciever is working did you try to enable your remote via Settings -> MyOSMC -> Remotes?

But I need a working *.conf file to do that. So the first step would be to make the file then select it from Remotes menu.
I would like to add that I came to know after searching that I need to stop lircd_helper and then use irrecord so I tried the following:

sudo systemctl stop mediacenter
sudo systemctl stop lircd_helper@lirc0

then I started sudo irrecord -d /dev/lirc0 ~/my_remote.conf but there is no response
also I would like to mension that my remote follows the RC-5 protocol. I could have created the .conf file manually but I don’t know how to fill the header between begin remote and begin code.
I would really appreciate the help

Update…

I was able to use my remote finally using ir-keytable
What I did was I copied the working keytable in libreelec to my home directory and ran the follwing:

sudo ir-keytable -c -w ~/TT-4600
So I cleared the current keytable and loaded a new one and boom… It worked.
Not all the buttons were mapped correctly so I hade to install Keymap editor and adjust the keys that did not work, although the return button was the only one that I was not able to map. This is strange because this keytable works perfectly without any modification in libreelec.

I would appreciate if any one could please explain what is the problem with irrecord why it is not working for me despite the fact that i have stopped lircd_helper using lircd_helper@lirc0 and then tried to run irrecord -d /dev/lirc0 ~/myremote.conf but I ended with:

Hold down an arbitrary key
Timeout (10 sec), giving  up.

no noise was detected in the step prior to the timeout.

I would really love to map the remote using irrecord instead and make a conf file.

Update2…
So I think I’m getting somewhere…
first of all I stopped the following:

sudo systemctl stop mediacenter
sudo systemctl stop eventlircd
sudo systemctl stop lircd_helper@lirc0
sudo systemctl stop system-lircd_helper.slice
sudo systemctl stop lircd_helper@event0
sudo systemctl stop lircd_helper@-dev-input-event0

I don’t know if some of these commands are redundant, I just applied all of them.

then when I ran ir-keytable this is the output:

Found /sys/class/rc/rc0/ (/dev/input/event0) with:
        Name: TechnoTrend TT-connect S2-4600
        Driver: dw2102, table: rc-tt-1500

        Repeat delay = 500 ms, repeat period = 50 ms

and then when I ran sudo mode2 -d /dev/input/event0 this is the output:

and after pressing ctl+c I started sudo irrecord -d /dev/input/event0 ~/temp.conf
I used temp.conf because at first I want to creat the conf file from scratch without the help of any template and at first irrecord asked me to keep pressing a key

Enter name of remote (only ascii, no spaces) :tt4600
Using tt4600.lircd.conf as output filename

Hold down an arbitrary key
................................................................................
Found gap (259967 us)

Please enter the name for the next button (press <ENTER> to finish recording)

and after that I started to record 5 keys just to try it, and this was the output:

begin remote

  eps            30

          KEY_RIGHT                0x0D50
      end codes

end remote

I don’t really know if it is correct or not but any way copied it to /etc/lirc and selected it from my osmc->remotes and rebooted. It did not work.

As a seconed try I tried to record based on a conf file from the same manufacturer that I found in the LIRC remote database online and which I copied it to a file and named it tt3600.conf and ran sudo irrecord -d /dev/input/event0 ~/tt3600.conf and this was the output:

begin remote

          KEY_DOWN                 0x0551
          KEY_LEFT                 0x0D4E
          KEY_RIGHT                0x0550
      end codes

end remote

Same thing I did and copied it to /etc/lirc and selected it from my osmc->remotes and rebooted but it didn’t work either.

Here is my LOG after I kept the conf file generated from scratch and selected in my osmc->remotes LOG

Please If anyone could tell me what I’m doing wrong I would appreciate that
