12d04a09aSmilamikica# Welcome to BTstack 22d04a09aSmilamikica 3bac2979aSMilanka RingwaldBTstack is [BlueKitchen's](http://bluekitchen-gmbh.com) implementation of the official Bluetooth stack. 4bac2979aSMilanka RingwaldIt is well suited for small, resource-constraint devices 52d04a09aSmilamikicasuch as 8 or 16 bit embedded systems as it is highly configurable and comes with an ultra small memory footprint. 62d04a09aSmilamikicaA minimal configuration for an SPP server on a MSP430 can run in 32 kB FLASH and only 4 kB of RAM. 72d04a09aSmilamikica 82d04a09aSmilamikicaIt connects to the Bluetooth modules via different Bluetooth HCI transport layers (e.g., HCI H4 UART and 92d04a09aSmilamikicaH5 the "Tree-Wire" protocol). The various platforms can be easily targeted by providing the necessary 102d04a09aSmilamikicaUART, CPU, and CLOCK implementations. 112d04a09aSmilamikica 122d04a09aSmilamikicaOn smaller embedded systems, a minimal run loop implementation allows to use BTstack without a Real Time OS (RTOS). 132d04a09aSmilamikicaIf a RTOS is already provided, BTstack can be integrated and run as a single thread. 142d04a09aSmilamikica 152d04a09aSmilamikicaOn larger systems, BTstack provides a daemon that connects to a Bluetooth module. 162d04a09aSmilamikicaMultiple applications can communicate with this daemon over different inter-process communication methods. 172d04a09aSmilamikica 182d04a09aSmilamikicaBTstack supports both, the Central and the Peripheral Role of Bluetooth 4.0 Low Energy specification. 192d04a09aSmilamikicaIt can be configures as both a single mode or a dual mode stack. 202d04a09aSmilamikica 21*cd07fdb2SMilanka RingwaldFor starters, download the [BTstack Manual](https://github.com/bluekitchen/btstack/raw/master/docs/manual/btstack-manual.pdf) 222d04a09aSmilamikicaand look for an Architecture overview and the Getting started example for MSP430. 232d04a09aSmilamikica 242d04a09aSmilamikicaBTstack is free for non-commercial use.

This summer, we plan to qualify for Bluetooth Core 4.2, 282d04a09aSmilamikicatogether with LE Central, PAN/BNEP and HSP. 292d04a09aSmilamikica 302d04a09aSmilamikica## Supported Protocols 312d04a09aSmilamikica* L2CAP 322d04a09aSmilamikica* RFCOMM 332d04a09aSmilamikica* SDP 342d04a09aSmilamikica* BNEP 352d04a09aSmilamikica* ATT 362d04a09aSmilamikica* SM 372d04a09aSmilamikica 38bac2979aSMilanka Ringwald 392d04a09aSmilamikica## Supported Profiles 402d04a09aSmilamikica* GAP 412d04a09aSmilamikica* IOP 422d04a09aSmilamikica* SPP 432d04a09aSmilamikica* PAN 442d04a09aSmilamikica* GATT 45bac2979aSMilanka Ringwald 46bac2979aSMilanka RingwaldComing soon: HSP, HFP, and more. 47bac2979aSMilanka Ringwald 48bac2979aSMilanka Ringwald## Supported Platforms 49bac2979aSMilanka Ringwald 50*cd07fdb2SMilanka Ringwald#### Embedded Platforms: 51*cd07fdb2SMilanka Ringwald* ez430-rf2560 52*cd07fdb2SMilanka Ringwald* msp-exp430f5438-cc2564b 53*cd07fdb2SMilanka Ringwald* msp430f5229lp-cc2564b 54*cd07fdb2SMilanka Ringwald* stm32-f103rb-nucleo 55*cd07fdb2SMilanka Ringwald* pic32-harmony 56*cd07fdb2SMilanka Ringwald 57*cd07fdb2SMilanka Ringwald 58*cd07fdb2SMilanka Ringwald#### Other Platforms: 59*cd07fdb2SMilanka Ringwald* posix 60*cd07fdb2SMilanka Ringwald* libusb 61*cd07fdb2SMilanka Ringwald* iOS 62*cd07fdb2SMilanka Ringwald* mtk 63*cd07fdb2SMilanka Ringwald* java 64*cd07fdb2SMilanka Ringwald 65*cd07fdb2SMilanka Ringwald 66bac2979aSMilanka Ringwald 67bac2979aSMilanka Ringwald## Supported Chipsets 68bac2979aSMilanka RingwaldChipsets | Status 69bac2979aSMilanka Ringwald-------------- | ------ 70bac2979aSMilanka RingwaldTI CC256x | complete, incl. eHCIll support 71bac2979aSMilanka RingwaldCSR 8811, 8510 | H4 only 72bac2979aSMilanka RingwaldEM 9301 | experimental use on Arduino Shield 73bac2979aSMilanka RingwaldCSR USB Dongles | complete 74bac2979aSMilanka RingwaldBroadcom USB Dongles | complete 75bac2979aSMilanka Ringwald 76
