Zephyr comes integrated with a feature-rich and higly configurable
|
|
Bluetooth stack:
|
|
|
|
* Bluetooth 4.2 compliant
|
|
* Generic Access Profile (GAP) with all possible roles
|
|
|
|
* Peripheral & Central
|
|
* Observer & Broadcaster
|
|
|
|
* GATT (Generic Attribute Profile)
|
|
|
|
* Server (to be a sensor)
|
|
* Client (to connect to sensors)
|
|
|
|
* Pairing support, including the Secure Connections feature from Bluetooth 4.2
|
|
|
|
* IPSP/6LoWPAN for IPv6 connectivity over Bluetooth LE
|
|
|
|
* IPSP node sample application in ``samples/bluetooth/ipsp``
|
|
|
|
* Clean HCI driver abstraction
|
|
|
|
* 3-Wire (H:5) & 5-Wire (H:4) drivers available
|
|
|
|
* Verified with multiple popular controllers
|
|
* Supporting both nano- & micro-kernels
|
|
* Highly configurable
|
|
|
|
* Features, buffer sizes/counts, stack sizes, etc.

Source tree layout
|
|
==================
|
|
|
|
The stack is split up as follows in the source tree:
|
|
|
|
``net/bluetooth/``
|
|
The core stack itself. This is where the HCI command & event handling
|
|
as well as connection tracking happens. The implementation of the
|
|
core protocols such as L2CAP, ATT & SMP is also here.
|
|
|
|
``include/bluetooth/``
|
|
Public API header files. These are the header files applications need
|
|
to include in order to use Bluetooth functionality.
|
|
|
|
``drivers/bluetooth/``
|
|
HCI transport drivers. Every HCI transport needs its own driver. E.g.
|
|
the two common types of UART transport protocols (3-Wire & 5-Wire)
|
|
have their own drivers.
|
|
|
|
``samples/bluetooth/``
|
|
Sample Bluetooth code. This is a good reference to get started with
|
|
Bluetooth application development.
|
|
|
|
``tests/bluetooth/``
|
|
Test applications. These applications are used to verify the
|
|
functionality of the Bluetooth stack, but are not necessary the best
|
|
source for sample code (see ``samples/bluetooth`` instead).
|
|
|
|
``doc/bluetooth/``
|
|
Extra documentation, such as PICS documents.
|
|
