Carplay running, but no graphics only white screen about react-carplay HOT 7 CLOSED

Thanks for the info, could you supply abit more about how you installed the OS? Is this running on a headless pi? Are you using a custom desktop enviroment? If not was it the full OS or the light version? All errors point to not being able to open the x display.

Just to rule it out could you run the below commands and then start the application without sudo ?

echo "SUBSYSTEM==\"usb\", ATTR{idVendor}==\"1314\", ATTR{idProduct}==\"152*\", MODE=\"0660\", GROUP=\"plugdev\"" | sudo tee /etc/udev/rules.d/52-nodecarplay.rules

Please try without sudo, when your phone connects you should see "Connect iPhone to begin carplay".

You will see in the console that the data arrives however the stream should still not be visible. Once you toggle carplay in the iPhone settings off and back on again, CarPlay should be visible.

This would be a replication of the behavior I mentioned in the other issue where the status state of the CarPlay component apparently needs to be updated twice in order for the stream to be revealed. Confirmed this issue with @Tigo2000 as well on the latest react-carplay as well as volvo-rtvi.

Cheers

@kostasfe the commands don’t do much, they just allow non root permissions to access the carlinkit (matches product and vendor ID) the issue won’t come back, just make sure you add those rules on any install (or use the setup-pi.sh script which does it for you)

if you tried to run without sudo before doing the command you would have had an error there too!

@LRYMND Could you elaborate? I am not seeing that issue my side. Are you having to do that on every run?

@rhysmorgan134 thank you for the swift answer. After running your commands and the application without sudo it worked like a charm. Including the wireless option.

However, I'm not sure what the commands actually do, therefore, not sure if they helped or just running without sudo did, as I have always used sudo in previous attempts.

Any suggestions of what I should do if the problem repeats? Also would be curious to know what your commands actually did thanks.

By the way, not sure if still relevant, but to your questions: I installed the os through the official Raspberry Pi Imager onto an SD Card. The Pi is headless and the OS is completely clean and empty, no custom desktop env. Both Buster and Bullseye were full versions.

@LRYMND thanks for the comment. I did get the "Connect iPhone to begin carplay", but it connected seconds after I plugged in the phone without the need to toggle Carplay in the settings.

I tested a bit more extensively with react-carplay now and you are right, the connection does in fact establish right away without needing to toggle. Maybe my dongle was asleep or something... Interesting though that Tigo experienced the same behaviour. However the problem with navigating from and to the carplay component persists and you have to toggle it in the settings to reveal it again.

@rhysmorgan134 many thanks. By the way, the wireless option seems to be snappier versus using it when running LineageOS Android 11 and Android Autokit.apk on the same PI. Well done!
