As sockets are used for client/server communication, it's easy to interact via higher-level level languages, e.g. Multiple applications can communicate with this server over different inter-process communication methods. On larger systems, BTstack provides a server that connects to a Bluetooth module. If a RTOS is already provided, BTstack can be integrated and run as a single thread. On smaller embedded systems, a minimal run loop implementation allows to use BTstack without a Real Time OS (RTOS). 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.


Targeting a variety of platforms is as simple as providing the necessary UART, CPU, and CLOCK implementations. Such as 8 or 16 bit embedded systems as it is highly configurable and comes with an ultra small memory footprint. It is well suited for small, resource-constraint devices BTstack is BlueKitchen's implementation of the official Bluetooth stack.
