Bluetooth overview

(Copied mostly from

)

• *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.
