Hi,

I think this is the exact same issue encountered on the Starlite Mk V

I have bisected the issue with a generic LE bluetooth keyboard here:
https://github.com/StarLabsLtd/firmware/issues/180#issuecomment-2732540740

And currently have that keyboard working on the Starlite Mk V with kernel
6.13.8 as it was working before with kernel 6.1.131 lts.

The change made to have it work is the following:

```

    Bluetooth: btintel, don't reclassify signal for GfP2 and GaP

    Should fix issue with LE devices not being found or able to connect.

This is not the real fix I guess since that reclassification of the pkt_type is
not there for no reason. But the skipping of it works around the issue

Hopefully this helps someone to find the actual issue
