This seems a bit odd, but it actually has three different reasons for it:
- It's a visual indication of BT LE mode for users
- the rfcomm code only works with legacy BT support, and if we scan a
device that only does LE, we want the custom serial code to instead
automatically fall back on a "emulate serial over LE packets" model.
- we want rfcomm to remain the default for devices that do both legacy
BT _and_ LE, but we want people to have the ability to override the
choice manually. They can now do so by just editing the address
field and adding the "LE:" prefix manually, and it automatically gets
saved for next time.
So while a bit hacky, it's actually a very convenient model that not
only works automatically, but allows the manual override.

This is some very early and hacky code to be able to access BLE-enabled
dive computers that use the GATT protocol to send packets back and forth
(which seems to be pretty much all of them: a vendor-specific GATT
service with a write characteristic and a notification characteristic
for reading).
For testing only. But it does successfully let me download dives from
my EON Steel and my Scubapro G2.
NOTE! There are several very hacky pieces in here, including just
"knowing" that the write characteristic is the first one, and the
notification characteristic is second. The code should actually check
the properties rather than have those kinds of hardcoded assumptions.
It also checks "vendor specific" by looking at the UUID string
representation, and knowing that the standard ones start with zero.
Crazily, there doesn't seem to be any normal way to test for this,
although I guess that maybe the uuid.minimumSize() function could be
used.
There are other nasty corners. Don't complain, send me patches.
