Hmm. The ble-prep branch really should change absolutely nothing
(because it ends up using the exact same code) apart from the printout
of

  Using bluetooth mode 2

that means that it just uses the ble functions (but those functions
are currently the exact same functions as the non-BLE ones).

And in fact the pairing code doesn't even trigger *that* difference.

The fact that it then later worked makes me wonder if your problem is
simply intermittent. The BT code has definitely been flaky for people,
just judging by the discussions even outside of this whole ble-prep
thread..
