  • CEC Settings Pulse Eight Adapter Philips 6007K

    Quote from hugosboss

    Off-topic: This CEC issue also occurs with my stock Fire TV 4K stick.

    Then it directs to an issue of your TV/Remote control/Cabling/AVR ... - not to KODI itself.

    Background: The remote control signal is received by your TV and translated to CEC. If the translation is faulty, then it occurs at all devices do you trying to control. Sometimes a firmware update of the TV or AVR is required to fix that.

    Common solution for typical CEC hiccups: Make all involved devices powerless at the same time for some minutes. This helps to reset the CEC settings.

  • [RPi] Argon ONE Control Add-on (Support Thread)

    I can see some possible culprits in your config.txt. But it could be, that you have a general issue with I2C currently.

    It's a typo in the documentation of Argon40. If you want to force the PCIe speed to Gen 3, the line should show like this.

    Code
    dtparam=pciex1_gen=3

    For the troubleshooting purposes, please comment out the last 3 lines via a hashtag in your config.txt first:

    Code
    #dtparam=i2c_arm=on
#dtparam=i2c_vc=on
#dtoverlay=i2c-bcm2708

    Please don't forget to reboot after that changes, connect to LE via SSH and try the following:

    • Stop KODI service
      systemctl stop kodi
    • Check the current I2C state.
      i2cdetect -y 1

    Please post the output of the i2cdetect command. If the address 0x1a isn't populated, make the case some seconds powerless (unplug the power supply) and try again afterwards.

    EDIT: Your log looks like, that you have installed some banned components which are in conflict with the forum rules. Please do not expect any further support until you come back with a fresh install without such things.

  • [RPi5] Wifi Remote Lag?

    A big distance between different RF transmitters is always better. Some also reported poor WiFi signal from the RPi5. As HiassofT and Da Flex have already tried to point in this direction.

    2.4 GHz is a free usable frequency range worldwide (surely with some exceptions). Nearly all modern RF devices flooding the air with their signals. Bluetooth and DECT is also there. So you must try it to find if you run into issues. For example if you near of a microwave oven (maybe on backside of the kitchen wall with your RPi5) you have another potential issuer in that frequency range.

  • CEC Settings Pulse Eight Adapter Philips 6007K

    There are 2 different settings which are related to your case:

    • Remote button press repeat rate (ms)
      At this interval, the button is automatically repeated as soon as you press the
      for longer than the following setting
    • Remote button press delay before repeating (ms)

    So play a bit with the second setting first. For my TV this combination works better than the default values:

    • Remote button press repeat rate (ms): 100ms
    • Remote button press delay before repeating (ms): 200

    Regarding the xml file, please install a recent nightly build of LE12. There was an attempt to support CEC at both HDMI ports of the RPi4/5 at the same time. But this had some culprits and was reverted after release of 12.0.1. This patch wasn't restricted to the RPis.
    In addition, KODI must be stopped before changing such settings files via CLI, otherwise the values may be overwritten by the running process.

  • [RPi] Argon ONE Control Add-on (Support Thread)

    In case of the Argon40 addon it is used to observe the shutdown pin GPIO4 for an incoming pulse. This pulse will be generated by the MCU at the pcb of the Argon ONE if:

    - Remote control power off command signal has been detected
    - The power button at the back side of the case has been double tapped
    - The power button at the back side of the case has been hold for 3 seconds at least, but shorter than 5 seconds

    The pulse time for double tap is 20-30ms, for the other ones is 40-50ms. If one of these is detected by the addon, KODI and therefore the operating system will be informed by the addon immediately to initiate a reboot or a shutdown, depending of the mapped event to the pulse time. The shutdown signal is the more critical moment and cannot be skipped, as the MCU starts an internal timeout of approx. 10 seconds until it switches off the power - regardless of whether KODI/the operating system is ready or not. Additionally, KODI has an internal timeout until it tries to kill running threads after 5 seconds during process stopping. But this seems counterproductive in the case of the default Python modules lgpio and gpiozero (due to some bugs) and leads to a fixed timeout of 30 seconds for the KODI process.

    That is the reason to have a library which is able to fast release the resources (below the KODI 5 seconds limit) to have mostly a properly shutdown.

    EDIT:
    Okay, after reading again. If you're thinking in terms of extending functionality using the GPIOs, it's up to you to find some real-world applications. Like rolling or unrolling canvases, triggering an actuator for a fire extinguisher above the housing or something like that. ;)

  • [RPi] Argon ONE Control Add-on (Support Thread)

    The system-tools addon PRs (libgpiod) were applied today and currently building, so it could be available in the next days. Many thanks to the kindly and helpful support of the LE maintainers.

    Because I was asked several times for that and I think now it's time for, some minutes ago I opened 2 pull request to possibly add the argonforty-device addon to the LibreELEC repo.

  • [RPi5] 4K/60Hz on LibreELEC 12.0.1

    ARC is only necessary for the connection TV -> AVR/soundbar, to provide the sound from TV back to the sound system via HDMI. So reserve that port for your AVR, if it also supports ARC. Your RPi doesn't use that kind of connection, so you could use another HDMI as well.

  • SmartTV+LibreelecPC

    If your PC is not housed in a shielding enclosure and/or to near the TV, it can radiate into your antenna cable and block the TV signal. Please check the isolation of your antenna cable and the used HDMI cable, sometime also another power supply for the PC.
    I had encountered a similar problem with a friend who had a Bluetooth transmitter for headphones attached directly to the back of her new TV. The SAT tuner was unable to find a transponder until I found and removed this construction.

  • [RPi4] Frequent Core Dump

    Please can you check if that happens too when:

    • move the cabeling to the primary HDMI port of your RPi4
    • use a recent LE 12 nightly
    • without additional USB devices like keyboard and so on ...
    • connected directly to the TV set (bypassing the DENON AVR)

    Do you have an alternative power supply available for a cross check?

    Quote from ApexDE

    Thanks! Will the updated rpi-tools come to LibreElec Updates?

    Maybe I was to ambigous or you just overlooked the known issue part of the documentation at my GitHub repo. ;) Some days ago I started this thread and provided the required changes, which are the base of my updated rpi-tools packages.

    RPi-Tools with official Python bindings for libgpiod

    Are there a chance that the Python bindings for libgpiod are official included into the virtual rpi-tools addon? libgpiod is already part of the system-tools addon, only the python bindings are currently missing.

    https://github.com/brgl/libgpiod/tree/v2.2.x/bindings/python
    https://pypi.org/project/gpiod/#description

    Why?

    Since LibreELEC 12 gpiozero is the main module intented to interact with the GPIO pins. But there are some ugly problems:

    • gpiozero takes to long to terminate (killed by KODI after 5

    The workflow is started, and the 2 open pull request were already tagged. As it depends on the available time of the LE maintainers, it may take some time until someone is in the mood to review and finally merge them. Afterwards it should be general available via LE addon updates and its not required anymore to download/install the rpi-tools additional from my repo to use gpiod.

  • [RPi] Argon ONE Control Add-on (Support Thread)

    Version 1.1.4 released:

    • added gpiod support
    • use gpiod if available, as workaround against the 30 seconds delay on restart/stop of KODI with LE12+ -> reduced to 5-6 seconds
    • regression with LE12/13: properly shutdown via power button of remote control possible again

    :!:This change will only take effect if rpi-tools are updated as well. Please read the known issue part, if you can't wait... ;)


    Hi firefox ,

    that was really fast. To get a feedback before publishing the release package. :D
