Bluetooth overview
==================

(Copied mostly from
http://urnenfeld.blogspot.de/2012/07/in-past-i-got-to-know-that-motivation.html)

**L2cap under ``network/protocols/l2cap``**: Provides socket interface
to have l2cap channels. L2CAP offers connection oriented and
connectionless sockets. But bluetooth stack as this point has no
interchangeability with TCP/IP, A Higher level Bluetooth profile must be
implemented

**HCI under ``src/add-ons/kernel/bluetooth``**: Here we have 2 modules,
one for handling global bluetooth data structures such as connection
handles and L2cap channels, and frames

**H2generic under ``src/add-ons/kernel/drivers/bluetooth``**: The USB
driver, implementing the H2 transport.

**Bluetooth kit under ``src/kit/bluetooth``**: C++ implementation based
on JSR82 api.

**Bluetooth Server under ``src/servers/bluetooth``**: Basically handling
opened devices (local connected fisically in our system) and forwaring
kit calls to them.

**Bluetooth Preferences under ``src/preferences/bluetooth``**:
Configuration using the kit

**Test applications under ``src/tests/kits/bluetooth``**.

There is a small prototype component which is not here documented below
src/add-ons/bluetooth/ResetLocalDevice. Its intention was to be an
add-on of bluetooth preferences, So that new HCI commands could be
customized by users or external developers. I did not like at the end
the idea, I did not find the flexibility I wanted.
