# Welcome to BTstack
|
|
|
|
BTstack is [BlueKitchen's](http://bluekitchen-gmbh.com) implementation of the official Bluetooth stack.
|
|
It is well suited for small, resource-constraint devices
|
|
such as 8 or 16 bit embedded systems as it is highly configurable and comes with an ultra small memory footprint.
|
|
A minimal configuration for an SPP server on a MSP430 can run in 32 kB FLASH and only 4 kB of RAM.
|
|
|
|
It connects to the Bluetooth modules via different Bluetooth HCI transport layers (e.g., HCI H4 UART and
|
|
H5 the "Tree-Wire" protocol). The various platforms can be easily targeted by providing the necessary
|
|
UART, CPU, and CLOCK implementations.
|
|
|
|
On smaller embedded systems, a minimal run loop implementation allows to use BTstack without a Real Time OS (RTOS).
|
|
If a RTOS is already provided, BTstack can be integrated and run as a single thread.
|
|
|
|
On larger systems, BTstack provides a daemon that connects to a Bluetooth module.
|
|
Multiple applications can communicate with this daemon over different inter-process communication methods.
|
|
|
|
BTstack supports both, the Central and the Peripheral Role of Bluetooth 4.0 Low Energy specification.
|
|
It can be configures as both a single mode or a dual mode stack.
|
|
|
|
For starters, download the [BTstack Manual](https://github.com/bluekitchen/btstack/blob/master/docs/manual/btstack-manual.pdf)
|
|
and look for an Architecture overview and the Getting started example for MSP430.

|
|
The Serial Port Profile (SPP) and the Bluetooth 4.0 Low Energy Peripheral role (LE Peripheral) have been qualified with
|
|
the Bluetooth SIG (QD ID 54558). This summer, we plan to qualify for Bluetooth Core 4.2,
|
|
together with LE Central, PAN/BNEP and HSP.
