Arghhhh… When I changed Kodi GUI resolution to 3840x2160 23,98 Hz I lost signal so this is reason. How to back GUI to 1980x1080 50 Hz while I see nothing on TV’s screen?
Edit:
Connected directly to TV and set back GUI 1980x1080 50 Hz.
Whitelisted everything except 4096x2160 and 3840x2160p 23,98 Hz and… EVERYTHING is OK.
Finally…
Thanks to all for your time and support…
You are doing amazing work here… 
I’d probably agree with this with my LG.
When I used it on the c2 I would disable libcec in peripheral settings and it worked almost perfectly.
With the n2 it wouldn’t work at all with it disabled but I didn’t think anything of it.
Now when I was able to sorted out CEC and lack of 4K output problems on my system (N2 → Denon AVR → OLED Panasonic) the only remaining issue is audio formats as described above.
Looking forward for HardKernel’s devs do the work that I’m sure will be successfully implemented by CoreELEC devs…
Keep your work guys…best regards…
same issue here with BT, using a Harmony Hub. When I navigate into CE addon via remote app on phone, it seems that the wifi/BT info under CE addon takes a good 30s to populate, after which I can reconnect the BT remote. Still an issue on 6/7 build
Yes I did.
I’ve now switched back to the latest nightly and to be honest things work about as well, so the improvement I saw with the test build may have been a coincidence. With rabaraf’s settings (post #1954) most remote buttons work fine, but play/pause etc work sporadically if at all. No biggie for me as I generally use a non-CEC remote.
I have a liveTV issue. Switching to a 4k channel and back to a 1080i channel changes the colors. Everything seems overcolored. The 4k channel always looks ok.
I guess dmesg is not the right log? What do you need?
dispinfo 1080i: http://ix.io/1Lo3
dispinfo 4k: http://ix.io/1Lo4
dispinfo 1080i: http://ix.io/1Lo6 (weird colors)
It seems that the colorspace and the resolution stay after 4k->1080i?
UPDATE: Now suddenly (without doing anything) the screen turned black and when it returned after 2s the color is okay. I ran dispinfo but I didn’t get a new link…
So maybe nothing changed in the logs but the colormap did? Weird?
I’m having an issue with CEC and was wondering if there is a setting that can fulfill my needs. What I’m after is a way to turn on the N2 on CEC events, but to NOT turn on the TV when starting the N2 through WOL or rtc wakealarm.
My use case is that I want to use the N2 as a little server that does more than just hosting kodi. Thus, the TV should not be turned on whenever the N2 wakes up to do something (especially when that is in the middle of the night).
I set the ‘Devices to power on during startup’ in the CEC Adapter settings to ‘None’, but the TV still turns on when the N2 wakes up. Only when I also disable the ‘Switch source to this device on startup’, it works correctly and the TV does not turn on anymore.
However, without this option, I seem to have more CEC issues with the TV sometimes not handing control to the N2 until I switch input back and forth once.
Is there a recommended way to set this up or is it impossible to get this right with CEC? Basically I’d need a setting to ‘Only Switch source to this device when NOT started through WOL or RTC’. Does this make sense?
I don’t know what TV brand you have but for my Panasonic powering off and on TV while watching something on Kodi brings back Stop, Pause, Next (>>|) and Previous (|<<) buttons functionalities.
Hello.
Some news about USB WIFI not working?
Here is my dmesg about this.
2.037693@2] usb 1-1.4: New USB device found, idVendor=0bda, idProduct=c811
[ 2.037696@2] usb 1-1.4: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 2.037698@2] usb 1-1.4: Product: 802.11ac NIC
[ 2.037700@2] usb 1-1.4: Manufacturer: Realtek
[ 2.037701@2] usb 1-1.4: SerialNumber: 123456
[ 2.049225@2] usb 1-1.4: Unsupported device
Thank’s: +1:
no news because nobody reported an issue
Thank you.
I thougt it is known that some USB WIFI Devices are not working (not recognised) on USB3 Ports.
And Hardkernel is working on that. Maybe wrong information or other device.
So i am wrong, my fault, sorry.
Beside that my USB WIFI with RTL8811AU is not working.
Can i do anything for support: dmesg or somthing more helpfull?
Strange, I also have a wifi dongle with RTL8811AU chipset, (Edup AC1619 600 Mbps WiFi) and that one works perfect on CoreElec.
My dongle did not work in Android, but with the help from @odroid on forum.odroid.com sorted it out just today. So now my dogle works OK on CE, Ubuntu and Android.
@mk3 wrong information, this is nothing to do with the devices not being recognised issue, the dmesg you gave points to your device being based on RTL8811CU and not RTL8811AU.
We already have a driver for RTL8811AU that works as this is what the Hardkernel Wifi Module 5A is based on, we do not have a driver for the RTL8811CU based adapters.
I will try to build a driver that you can use for your dongle.
Thank you adamg.
Because there is RTL8811AU in the description of the product i bought it.
Now it turns out it is a RTL8811CU…so as a customer…wtf…
best regards
@mk3 I have compiled a driver for your device however you will have to load it manually via SSH and tell me if it works, if it does then I will make sure it is included in tomorrows nightly.
Enter the following commands via SSH.
wget https://test.coreelec.org/8821cu.ko
insmod ./8821cu.ko
After doing this return to CE-settings and see if you can see the networks.
RTL8811CU is a much better chipset than RTL8811AU, it’s 5 years newer and supports Wave2 so I would not be complaining.
Thank you very much adamg.
It is working, so in the next nighly it is permanent…great 
Changes have been pushed, thanks for reporting back.
@Comma @MrChromebox I took a look to the dmesg and it looks like the “hidp” module is not getting loaded. I do have here a wireless mouse (Cherry MW 2310), It says bluetooth but I don’t know…
I just can use the mouse without any pairing. In CE settings there is no BT adapter found.
Please enter lsmod in a terminal when it is working and when it is not working.
Like 05/30 is working, 05/31 not, Comma said.
Here you go, sorry about the missing spaces.
