remote control commands executed twice

[Marsu31]

Hi,

Hardware : raspberry 2 with GPIO IR receiver (TSOP4838), Logitech Harmony emulating MCE-1039 remote. Software : xbian up to date

The MCE-1039 is recognized as "mceusb" remote. When I use it the moves are executed twice, this is the kodi.log for one click on right arrow :

DEBUG: Keyboard: scancode: 0x6a, sym: 0x0113, unicode: 0x0000, modifier: 0x0
DEBUG: OnKey: right (0xf083) pressed, action is Right
DEBUG: LIRC: Update - NEW at 39604:000000037ff07bde 00 KEY_RIGHT mceusb (KEY_RIGHT)
DEBUG: OnKey: 168 (0xa8) pressed, action is Right

The "OK" is not executed twice :

DEBUG: LIRC: Update - NEW at 3389751:000000037ff07bdd 00 KEY_OK mceusb (KEY_OK)
DEBUG: OnKey: 11 (0x0b) pressed, action is Select

If I restart lirc the kodi.log becomes :

DEBUG: Keyboard: scancode: 0x6a, sym: 0x0113, unicode: 0x0000, modifier: 0x0
DEBUG: OnKey: right (0xf083) pressed, action is Right

but, in this case, the key "OK" doesn't work anymore.

I used irw to see what lirc understands and it returns exactly the keys I pressed, only once, not twice. It's like if the KEY_RIGHT was read twice, from 2 paths ? or 2 threads ?

is this a bug or a configuration issue ?

regards (sorry for my English)

Hi,

I have the same issue, latest version xbian running on a PI2, using HP MCE remote (usb connected IR), like you irw is right but xbmc move twice when using left or right arrow.

Did you find any solution?

[mkreisl]

Yes, there should be.

Please change (comment out) in all .conf files in folder /etc/lirc/hardware the parameter LIRCD_ARGS="-u" to #LIRCD_ARGS="-u" if there is one.

And then restart lirc and xbmc

sudo restart lirc
sudo restart xbmc

and try again.

For more information please type man lircd to see what the -u parameter does (Kodi reads some keys doubled from LIRC and standard Input events)

[jbkt]

Thx mkreisl, but it did not work.

I had this: xbian@xbian /etc/lirc/hardware $ grep LIRCD_ARGS *.conf custom.conf:#LIRCD_ARGS="" default.conf:#LIRCD_ARGS="" lirc_hb.conf:LIRCD_ARGS="-u" lirc_rpi.conf:LIRCD_ARGS="-u" logitech_ultrax.conf:#LIRCD_ARGS="" mceusb.conf:#LIRCD_ARGS="" mceusb_event0.conf:#LIRCD_ARGS="" mceusb_event1.conf:#LIRCD_ARGS="" mceusb_event2.conf:#LIRCD_ARGS="" srm7500libusb.conf:LIRCD_ARGS="" x10.conf:#LIRCD_ARGS="" xbox.conf:#LIRCD_ARGS="" So it was already diasblaed for all the MCE confs. I tried to change lirc_hb.conf and lirc_rpi.conf anyway, rebooted, but without success.

[mkreisl]

@jbkt What happens if you disable lirc completely?

[jbkt]

I haven't tried, but if I do this:

xbian@xbian ~ $ sudo ir-keytable -p RC-6 Protocols changed to RC-6

xbian@xbian ~ $ ir-keytable Found /sys/class/rc/rc0/ (/dev/input/event3) with: Driver mceusb, table rc-rc6-mce Supported protocols: NEC RC-5 RC-6 JVC SONY SANYO LIRC RC-5-SZ SHARP XMP other Enabled protocols: RC-6 Name: Media Center Ed. eHome Infrared bus: 3, vendor/product: 0471:0815, version: 0x0000 Repeat delay = 500 ms, repeat period = 125 ms

It works !

Now I have to find out how to do this permanent.

[jbkt]

By defaut I have this:

xbian@xbian ~ $ ir-keytable Found /sys/class/rc/rc0/ (/dev/input/event3) with: Driver mceusb, table rc-rc6-mce Supported protocols: NEC RC-5 RC-6 JVC SONY SANYO LIRC RC-5-SZ SHARP XMP other Enabled protocols: RC-6 LIRC Name: Media Center Ed. eHome Infrared bus: 3, vendor/product: 0471:0815, version: 0x0000 Repeat delay = 500 ms, repeat period = 125 ms

It seems that is LIRC protocol that is the problem.

[mkreisl]

hmm, maybe you can add this command here (in file /etc/init/lirc.conf)

               if [ "$START_LIRCD" = "true" ]; then
                        echo "Starting remote control daemon(s) : LIRC "
                        LIRCD_ARGS=`build_args $LIRCD_ARGS`

                        if [ ! -z "$LIRCD_ARGS" ]; then
                                set -- $LIRCD_ARGS
                                /usr/local/sbin/lircd $@
                                                  # <--- put it in here
                        fi
                fi

                if [ "$START_LIRCMD" = "true" ]; then

[mkreisl]

Unfortunately I don't have such an IR receiver. I would assume that if you disable the LIRC protocol LIRC stops working ...

[jbkt]

You were right: if I stop lirc (sudo stop lirc) it is the same as if I do sudo ir-keytable -p RC-6: directional keys are working properly. But in both case the OK key is not working...

[jbkt]

This a true MCE remote (similar to this one: http://www.amazon.com/gp/product/B00KDNIRYA) that I bought a long time ago as it was working out of the box on XBMC. It still is on Kodi over Ubuntu or in Openelec.

[jbkt]

I have just checked on my Ubuntu box: LIRC protocol is used. So I have tried sudo ir-keytable -p LIRC and it work the same as RC-6. So it semms that using tow protocols as the same time was the problem: twice the events sent to Kodi. Now OK (and perhaps other keys) is still not working even if I see the key pressed using irw, so I guess it is due to another configuration problem.

[mkreisl]

This would make sense :smile:

Yes, this is a configuration problem in Kodi. You have to edit the Lircmap.xml. To do this, please copy the file /usr/local/share/kodi/system/Lircmap.xml to /home/xbian/.kodi/userdata/ end edit it there (do never edit the original, it will be overwritten when next update comes)

[jbkt]

I have copied /usr/share/kodi/system/Lircmap.xml from ubuntu into* /home/xbian/.kodi/userdata/* and the OK button works, but I still have the events in double. if I diable LIRC `sudo ir-keytable -p RC-6 the events are not in double but the Lircmap.xml is ignored.

So what is managing RC events when LIRC is off? Caqn I disable that and use LIRC only?

[mkreisl]

So what is managing RC events when LIRC is off? Caqn I disable that and use LIRC only?

Kodi reads them directly from (u)input events Try unloading uinput module (sudo rmmod uinput)

[mkreisl]

Another possible solution would be using inputlirc instead of lirc

[ccfiel]

I have this problem :( but this problem is not present in openelec.

[ccfiel]

@mkreisl I tried to so sudo rmod uinput it does not have double key entry but the enter/ok button does not work. I tried to do irw and press ok button in the remote lirc detects it

xbian@xbian ~ $ irw
000000037ff07bdd 00 KEY_OK mceusb
000000037ff07bdd 01 KEY_OK mceusb
000000037ff07bdd 00 KEY_OK mceusb
000000037ff07bdd 01 KEY_OK mceusb

but there is no action in kodi.

[ccfiel]

@mkreisl It works.

sudo ir-keytable -p LIRC I just put it /etc/init/lirc.conf and now its working! Thanks!

[mkreisl]

@ccfiel which version of xbian-package-lirc are you using? and could you please show me the place where you added this command?

and need some infos for integration into standard package, because /etc/init/lirc.conf would be overwitten by next update of package xbian-package-lirc:

is module mceusb loaded?

If yes, I could make a modification like this in /etc/init/lirc.conf:

                        if [ ! -z "$LIRCD_ARGS" ]; then
                                set -- $LIRCD_ARGS
                                /usr/local/sbin/lircd $@
                        fi

                        if lsmod | grep -qw mceusb && [ -e /sys/class/rc ]; then
                                ir-keytable -p LIRC || :
                        fi
                fi

                if [ "$START_LIRCMD" = "true" ]; then

Would be nice if you could test this, thanks :smile:

[eyal0]

@ccfiel Your solution worked for me, too.

As I understand it, the problem is that the same key press was getting interpreted twice: once as a keyboard and once as the remote. That's why it was in the log once each way.

When lirc was disabled, only the keyboard continued to work and only the directional keys. The OK button and all the others didn't work.

For some reason, the ir-keytable command fixed it for me. I can see in kodi.log that there are no more keyboard lines. Great!

[mkreisl]

@eyal0 Still got no answer from @ccfiel, could you please answer my questions, thanks

[eyal0]

@mkreisl I tried your patch, it didn't work. What else would you like to know?

[eyal0]

@mkreisl There is no "mceusb" in the output of lsmod

[mkreisl]

@eyal0 which version of xbian-package-lirc are you using?

no module mceusb loaded, ok. so my patch can not work

[mkreisl]

@eyal0 could you please try this patch? changed mceusb to rc_rc6_mce

                        if [ ! -z "$LIRCD_ARGS" ]; then
                                set -- $LIRCD_ARGS
                                /usr/local/sbin/lircd $@
                        fi

                        if lsmod | grep -qw  rc_rc6_mce && [ -e /sys/class/rc ]; then
                                ir-keytable -p LIRC || :
                        fi
                fi

                if [ "$START_LIRCMD" = "true" ]; then

[eyal0]

@mkreisl

Regarding version:

Previously I'd had the "Keyboard" line as in the first comment.

[mkreisl]

Great :+1:

You're using 'old' version, not the one in staging repository. So i'll modify new package, could you please test new version tomorrow?

I'm posting the link for downloading new package here tomorrow afternoon.

Thanks in advance

[eyal0]

Will I need to reverse the above patch?

Just detail what steps do to do install it and I'll try it, no problem.

It's very late here so I'm signing off. I'll be in front of a computer again in about 9 hours. Thanks for your help, it was very prompt!

[mkreisl]

@eyal0 Package for download and testing is ready :smile:

Will I need to reverse the above patch?

No, just download this package http://apt.xbian.org/pool/devel/rpi2-jessie/x/xbian-package-lirc/xbian-package-lirc_20170327_armhf.deb and install it with dpkg -i xbian-package-lirc_20170327_armhf.deb

[ccfiel]

Sorry for the late reply :( @mkreisl yes it work :) I really do not know what I did. What do you want me to check?

[mkreisl]

No problem, @eyal0 already answered my question.

If you want you could test new lirc package, see my previous post here

[ccfiel]

@mkreisl ok I will try. :) by the way great project. Keep it up! :+1:

[eyal0]

@mkreisl Sorry to say but now the remote isn't working at all! None of the buttons have any effect. Also, when I enable debug logging, I don't see any button presses in kodi.log. I'm able to control my system using the Kore app (Kodi remote control for Android phone). Here's a log of some stuff that I tried.

Do you know what the issue might be?

Also, can you point me to an older version so that I can get my remote working in the meanwhile? Thanks!

[mkreisl]

Bad news :disappointed:

to install older version, please run

sudo apt-cache policy xbian-package-lirc
audo apt-get install --reinstall xbian-package-lirc=1.5.1

Hard for me to debug, unfortunately do not have any mce rc :disappointed:

[eyal0]

The problem might have been other changes in that package and not the above few lines? Because thoes worked for me as a patch.

I'll try to do some debugging myself.

[mkreisl]

Thanks for your help. Must be another issue

[eyal0]

Here's what I know so far:

If I install the new version that you made yesterday, my remote stops working entirely. irw doesn't show anything. Using apt-cache and apt-get commands above to revert to lirc version 1.5.1 works and lets irw see my button presses again. However, there are the double-presses of the arrow keys again, back to where I start.

I tried this:

1. Install new version.
2. Copy /etc/init/lirc.conf to /etc/init/lirc.conf.new .
3. Copy /etc/lirc to /etc/lirc.new (the whole directory).
4. Reinstall the old version with the apt-get command above.
5. Copy over /etc/init/lirc.conf with lirc.conf.new .
6. Copy of /etc/lirc with /etc/lirc.new .
7. Restart the system.

That leaves me in a start when I've got 1.5.1 installed but lirc.conf and /etc/lirc are all from the new version that you supplied. In this situation, I'm able to use my remote and there are no double-presses, thanks to the ir-keytable -p LIRC in the new files.

So there is still something in the new version that isn't working with my setup but it isn't lirc.conf nor is it in /etc/lirc . What else is that new package doing? I dunno.

[mkreisl]

@eyal0 That's absolutely confusing me

All changes in lirc package were in /etc/lirc and oc /etc/init/lirc.conf. All binaries are rebuilt (that's part of the build process), but from same source file.

Just installed that version on my RPi3, seems to work with my X10 device. sudo irw shows all my key I press on the rc

Could you replace the binaries from /usr/local/bin and /usr/local/sbin/ I suppose only /usr/local/sbin/lircd is important

Btw, useful commands are apt-get download to download package and dpkg -x extracts all files from given deb to any folder you want

So you can download both versions, extract them in different folders and change files one after the other.

When lirc starts, it writes some messages into file /var/log/upstart/lirc.log. In my case it looks like

*** LIRC hardware (autodetected) ***
   SECTION=X10
   LOAD_MODULES=
   DRIVER=default
   DEVICE=/dev/lirc0
   MODULES=

If lirc does not work, is daemon lircd running ?

And again, thanks for your help

[mkreisl]

@eyal0

Oooops, I forgot to ask: what kind hardware do you have? That new package only runs on RPi2 or RPi3 and not on Rpi1

[eyal0]

@mkreisl Haha, none of those! I'm on a cubox, about 3 years old maybe.

[mkreisl]

I see, but that is same problem. cubox has cortex-a9, and rpi2,3 has cortex-a7 core, means that this package built for rpi2 (for cortex-a7) is not running on cubox. Will make package for i.MX6

[mkreisl]

@eyal0 Here we go, xbian-package-lirc for i.MX6: http://apt.xbian.org/pool/devel/imx6-jessie/x/xbian-package-lirc/xbian-package-lirc_20170331_armhf.deb

Checked on my Hummingboard - seems to work :smile:
