kobo-libra2-uhid-module VS rpi-audio-receiver

HERE’S THE GUIDE (if you buy the exact same ring as mine): 1. Please look it up on Aliexpress yourselves. I can't put the link here that's why my comment has been hidden the whole time so sorry :( 2. Download KoboRoot.tgz at: https://github.com/tsowell/kobo-btpt/releases/tag/v0.0.2 Then copy it into the .kobo folder of your eReader and eject it. After it installs, you'll see a .btpt folder on the device. 3. Download this file that I already tweaked: https://www.dropbox.com/s/k8vetyzas6sh83f/camera%20remote%20control?dl=0 Then copy it into the .btpt folder that was created earlier. 4. (FOR LIBRA 2 ONLY) Follow this guide to patch the uhid-module: https://github.com/tylpk1216/kobo-libra2-uhid-module After that, eject your Kobo and make sure to install the patch inside NickelMenu, it should show “insmod uhid.ko successfully”. 5. Connect the ring with your Kobo via Bluetooth and enjoy. Mine works this way: One-click - Next page, Double-click - Previous page. *NOTE that different remotes need to be configured differently. If you plan to use a different one please check out the FULL tutorial here: https://github.com/tsowell/kobo-btpt Feel free to DM me if you have any questions!

I once installed raspberry pi’s with a Bluetooth audio receiver config. These got installed in a professional football club with each receiver having a name like ‘changing room’ , ‘bar’, ‘manager’. They gave an open connection without PIN codes and lost the active connection as soon as the current device went out of range. We tried a number of ‘real’ Bluetooth devices from Denon and similar but none offered the configurable parts of the raspberrypi’s.

Check this out, it may help you - seems to be describing close to what you're after

When I play a song on my phone/computer that is played on my speaker via bluetooth, I want the lights to be synced to music, where the ceiling and wall lights will each have different effects. I’m thinking of installing LedFx on a Raspberry Pi 4 for music syncing. Do I need https://github.com/nicokaiser/rpi-audio-receiver for this?

This may be linked to be an ongoing conflict between WiFi and Bluetooth. I bought a Hifiberry amp to explore turning a raspberry pi into a receiver, and this GitHub project is amazing for that purpose, but suggests that the RasPi's onboard bluetooth and wifi interfere with each other. I'm intending to try a USB bluetooth dongle to see if it will fix but I'm encouraged by u/AlienMajik 's post above.

Not sure if this works for you https://github.com/nicokaiser/rpi-audio-receiver

I've seen https://github.com/nicokaiser/rpi-audio-receiver but not sure how to get the input from airplay and have it pair and output to the speaker.

I do this currently with spotify, as the rpi runs rpi-audio-receiver with the spotifyd daemon. I like this because from any spotify app I can switch the device over to the rpi and the music comes out of the speakers. I don't need to access any web server running on the pi or have a separate app for playing the music there.
