12d04a09aSmilamikica# Welcome to BTstack 22d04a09aSmilamikica 30a8d3146SMatthias RingwaldBTstack is [BlueKitchen's](https://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. 62d04a09aSmilamikica 743a197a7SMatthias RingwaldTargeting a variety of platforms is as simple as providing the necessary UART, CPU, and CLOCK implementations. BTstack is currently capable of connecting to Bluetooth-modules via: (H2) HCI USB, (H4) HCI UART + TI's eHCILL, and (H5) HCI Three-Wire UART. 82d04a09aSmilamikica 92d04a09aSmilamikicaOn smaller embedded systems, a minimal run loop implementation allows to use BTstack without a Real Time OS (RTOS). 102d04a09aSmilamikicaIf a RTOS is already provided, BTstack can be integrated and run as a single thread. 112d04a09aSmilamikica 126d743f9aSMatthias RingwaldOn larger systems, BTstack provides a server that connects to a Bluetooth module. 136d743f9aSMatthias RingwaldMultiple applications can communicate with this server over different inter-process communication methods. As sockets are used for client/server communication, it's easy to interact via higher-level level languages, e.g. there's already a Java binding for use in desktop environments. 142d04a09aSmilamikica 15e6a6f76bSMatthias RingwaldBTstack supports the Central and the Peripheral Role of Bluetooth 5 Low Energy specification incl. LE Secure Connections, LE Data Channels, and LE Data Length Extension. It can be configured to run as either single-mode stack or a dual-mode stack. 162d04a09aSmilamikica 1743a197a7SMatthias RingwaldBTstack is free for non-commercial use.
