KDE Connect missmatched pairing keys

Pairing phone to PC via pure Bluetooth is successful , pin matches and it works well.

When trying to pair KDE Connect over that Bluetooth connection the pins are mismatched

and when digging deeper the certs seem wrong

the one of PC is same on PC and on Android Phone

but the one of the Phone is mismatched on PC

if i accept they connect to each other even tho it’s mismatched

Linux 25.08.2 version from pacman

Android 1.33.9 from play store (same situation with F-droid 1.33.8 and 1.33.7)

I can confirm this. Today after some struggle I managed to connect my phone to my PC via Bluetooth for the first time (I had tried it a few times before, it had never worked), but I had to ignore the keys which were mismatched no matter which side initiated the pairing process.

(Another thing is that I couldn’t do anything useful with such connection, everything either didn’t work or was very laggy).

The keys match as they should when a wifi connection is used.
