  • Can I add WiFi config to SD card pre-install? (headless setup)

    Quote from azeam

    Yes, it's possible. Mount the SD card on your computer and create (as root):

    Code
    nano /where_sd_card_is_mounted/storage/.cache/connman/mywifi.config

    Add the following (change "mywifi" after "Name" to your SSID and "passphrase" to your passphrase), save the file and boot your pi:

    Code
    [service_wifi_mywifi]
Type = wifi
Name = mywifi
Passphrase = passphrase

    Hi chewitt

    The Libreelec connection flow has always been great apart from when installing a new instance without HDMI CEC, input peripheral or ethernet. I've had it happen a few times where something has failed and I've had to dig my emergency 50m ethernet cable out! Why can't we manually define the credentials in the LE settings? Surely it's as simple as generating this text file?

    Then if we enable WiFi tethering pre-install, once the WiFi credentials were known it could be entered via the GUI and a remote app like Yatse or XBMC Remote. Once the file is there and hotspot tether is disabled it will autoconnect.

    If it's something LE team are not interested in maybe someone with some basic python skills (not me or I would) could make a simple addon to create this file.

  • No HDMI signal from Raspberry Pi 4 after turning TV & Soundbar off and back on

    I have a similar issue with one of my RPi4's which is connected to a long cable to a Onkyo amp and LG TV. Occasionally, with no apparent pattern I will switch it on to find a blank screen on TV saying no input. There is something coming from it as it would normally be a blue screen from the Onkyo amp.

    The amp always remains on or on standby however the TV is switched off via a smart plug.

    I've managed to figure out how to get the picture back up without restarting.

    tvservice -p

    systemctl restart kodi

    I'm not sure if I have to do a tvservice -o then -p in between the restart as yet.

    This is the dmesg log which could show something. I did try unplugging a couple of times, powering the amp off/on and Kodi crashed a couple of times too so who knows which is the error. I'll try get a more specific one next time.

  • RPi4 WiFi intermittent crashes

    So I keep getting these issues and it's usually resolved by restarting my router which isn't helpful in getting to the bottom of it.

    I've noticed this in the journalctl:

    Code
    wlan0: CTRL-EVENT-ASSOC-REJECT bssid=00:00:00:00:00:00 status_code=16
wpa_supplicant[367]: wlan0: CTRL-EVENT-SSID-TEMP-DISABLED id=0 ssid="myssid" auth_failures=1 duration=10 reason=CONN_FAIL

    I can't see anything on my router logs which is weird. No other device is having this issue which is why I'm posting here. I suspect it's an issue between the two devices, I just need to figure out what it is.

  • Script to reconnect wifi

    EDIT: fixed this, the script wasn't in unix format!

    I'm struggling with this script, probably something simple but this is what I have:

    I get this error when running:

    Code
    autoconnectwifi.sh: line 26: syntax error: unexpected "done" (expecting "then")

    So after figuring my stupid mistake I found this other script and adapted it. This uses the wifi network instead of a ping, maybe better if for some reason the IP will change or unavailable. wifi_servicecode_managed_psk has been changed from what is listed in connmanctl services

    Bash
    #!/bin/bash

while true ; do
    if ifconfig wlan0 | grep -q "inet addr:" ; then
        sleep 60
    else
        connmanctl connect wifi_servicecode_managed_psk &>/dev/null
        sleep 10
    fi
done

  • DS3231 Real Time Clock installation guide for RPi / /LE8

    I guess this never got added to the wiki :( This line needs to be changed for other chips:

    Quote from frankvw

    3b. Edit /flash/config.txt and add (somewhere near the end): dtoverlay=i2c-rtc,ds3231

    with

    Code
    dtoverlay=i2c-rtc,ds1307

    or

    Code
    dtoverlay=i2c-rtc,pcf8523

    Also, I'm not sure if this step is necessary:

    Quote from frankvw

    4. Adjust the RTC's time:

    4a. Verify local system time with the 'date' command. If local time is off, either adjust it manually or connect your Pi to the Internet and wait for it to the the correct time from an NNTP server.

    4b. Transfer local time to RTC: hwclock -w

    4c. Verify RTC time: hwclock -r

    I've just added a used ds1307 rtc and the date from hwclock -r was UTC, I'm on GMT, so an hour behind. Doing hwclock -w and then rebooting with no network resulted in it being an hour ahead for some reason! It's now sorted itself out though and keeps the correct time after losing power and no network.

    Now I just need to figure out a script to keep trying to reconnect the wifi if it's unavailable after power loss. Then my pi might just get itself back ship shape after a rare power cut!

  • hide mouse pointer and boot / shutdown messages

    I've managed to achieve this on rpi 4 by adding the above to cmdline.txt in /flash so it looks like this:

    Code
    boot=UUID=xxxx-xxxx morequiet disk=UUID=xxxxxxxx-xxxxx-xxxx-xxxxxxx quiet systemd.show_status=0

    It works fine apart from I'm still seeing "waiting for network...." even though this option is disabled in LE settings. Enabling it just results in another line with the same. Any idea how I can suppress this as well?

  • RPi4 WiFi intermittent crashes

    I'm having a very intermittent issue with the onboard wifi adapter crashing on my RPi4 after some time (days or hours) of being connected and online. The connection will appear up in LE settings however I can't ping the device at all. Enabling and disabling the wifi does nothing, only a reboot works.

    I've had a look in the log and can't see anything related and am hesitant to turn on debug logging as this could happen hours or days after a boot and the log file would be huge. Here's a few things I've tried after getting onto it via a cable:

    dmesg

    Code
    connmanctl scan wifi
Error /net/connman/technology/wifi: No carrier
    Code
    iwconfig wlan0
wlan0     IEEE 802.11  ESSID:off/any
          Mode:Managed  Access Point: Not-Associated
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off

    Is there anything else I can try looking at before I get a debug log?

  • LibreELEC-RR 9.x [ Emulationstation | Retroarch | Pegasus | DolphinQT | Moonlight | Chrome | Spotify ]

    I updated to this build and it seems to work ok apart from Kodi will relaunch when I'm in ES or playing a game in Retroarch. Any idea why this is happening. RPi3 build.

  • update emby server to latest in libreelec repo?

    Hi awiouy thanks for getting back to me. I have updated all addons so I'm assuming dotnet is up to date. Output of journalctl -u service.emby4 is blank. I'll try refreshing the repo's see if it's missing an update.

    systemctl status service.emby4.service reports:

    Just seen an old thread re emby and this command might help? ldd $(which dotnet):

  • update emby server to latest in libreelec repo?

    Thanks for looking. I'm on the addon default 4.2 so I guess I can update to 4.3 at least for now. Where do we go to get this fixed? I'm guessing the maintainer for the addon is inactive due to it not being updated for a while. I was thinking of switching to Docker but I'm not sure how straight forward this would be.
