| 4# Welcome to BTstack 5 6BTstack is [BlueKitchen's](http://bluekitchen-gmbh.com) implementation of the official Bluetooth stack. 7It is well suited for small, resource-constraint devices 8such as 8 or 16 bit embedded systems as it is highly configurable and comes with an ultra small memory footprint. 9A minimal configuration for an SPP server on a MSP430 can run in 32 kB FLASH and only 4 kB of RAM. 10 11Targeting 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. 12 13On smaller embedded systems, a minimal run loop implementation allows to use BTstack without a Real Time OS (RTOS). 14If a RTOS is already provided, BTstack can be integrated and run as a single thread. 15 16On larger systems, BTstack provides a daemon that connects to a Bluetooth module. 17Multiple applications can communicate with this daemon over different inter-process communication methods. 18 | 1# Welcome to BTstack 2 3BTstack is [BlueKitchen's](http://bluekitchen-gmbh.com) implementation of the official Bluetooth stack. 4It is well suited for small, resource-constraint devices 5such as 8 or 16 bit embedded systems as it is highly configurable and comes with an ultra small memory footprint. 6A minimal configuration for an SPP server on a MSP430 can run in 32 kB FLASH and only 4 kB of RAM. 7 8Targeting a variety of platforms is as simple as providing the necessary UART, CPU, and CLOCK implementations.
