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 larger systems, BTstack provides a server that connects to a Bluetooth module.
Multiple 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.
BTstack 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.
BTstack is free for non-commercial use. However, for commercial use, <ahref="mailto:contact@bluekitchen-gmbh.com">tell us</a> a bit about your project to get a quote.
GATT Services are in general easy to implement and require short development time. For more GATT Services please contact us, or follow the [implementation guidelines](https://bluekitchen-gmbh.com/btstack/profiles/#gatt-generic-attribute-profile).
