Anything else I can do to help you diagnose this regression? One thing I do (vaguely) remember when building a custom kernel some time ago is that this device does some sort of "GATT encryption" (I'm sure I'm misremembering this, it's been a few years) and I couldn't connect to it either unless the appropriate config setup was used when building the kernel.
