Raspberry continous pairing requests solved by updating Bluez.

[CosminPerRam]

We had problems in communicating with Raspberry Pi Zero 2W's, everytime we were connecting to it, we would get asked to pair the device (the Raspberry is running a GATT server (Raspberry Pi OS Lite 64-bit 2024-11-19) and the (only) connecting device we would encounter this on is a Galaxy S23 (Android 14, One UI 6.1)).

Using Adapter::set_pairable wouldn't change this behaviour at all.

Then I saw that the host device was running Bluez 5.66 and since then there were some releases that has pairing-related issues solved, when updating it to latest (5.79, using this guide) the problems was gone.

I'm writing this as I couldn't find much info about this issue (neither how to properly debug it), hoping to help other people that would come across it.

If applicable, I can look further into this issue with guidance.
