Welcome to BTstack

BTstack is BlueKitchen's 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.

Targeting 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.

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 the Central and the Peripheral Role of Bluetooth 4.2 Low Energy specification. It can be configured to run as either single-mode stack or a dual-mode stack.

BTstack is free for non-commercial use. However, for commercial use, tell us a bit about your project to get a quote.
