Project Golden Gate
:warning: Work In Progress
This documentation is not yet complete. As we migrate the project from
an internal project to one that can be shared with others, we are busy
migrating some of the documentation from internal Wiki pages, Google docs
and slide decks.
Golden Gate is a portable cross-platform framework that offers reliable and
secure network communication between different combinations of embedded
devices, mobile applications and desktop applications over Bluetooth Low Energy.
The framework provides developers with a familiar model, allowing them to
implement their functionality the same way they would in other networked
environments, leveraging familiar standards like CoAP, WebSockets, HTTP, MQTT,
TLS, and TCP/UDP/IP, even when the underlying operating system or transport
doesn’t natively support those.
It can run in many environments, from embedded systems with very limited
resources like wearables and IoT devices, to mobile and desktop.
The initial focus is on Bluetooth Low Energy (BLE) connections, but the
framework is general in nature, it is designed to work with any type of
transport. BLE APIs on mobile operating systems like iOS and Android, as
well as most embedded APIs, only offer the limited functionality of BLE GATT;
so the Golden Gate framework’s networking stack extends that low-level access,
allowing a complete IP-based stack to be layered on top of it.
The project consists of:
- A core library written in C
- Language bindings for higher level languages, including Kotlin and Swift
- A modular build system based on CMake
- Code examples
- Tools and applications
- Support for test automation
- Documentation
By building the core libraries and sample applications included in the
project, you’ll be able to start experimenting right away with different
combinations of devices connecting and communicating with each other with
CoAP clients and servers, over a Bluetooth or WiFi connection, including:
- iPhones and iPads
- Android phones and tablets
- Desktops and laptops (macOS, Linux, Windows)
- Embedded development boards (Nordic nRF52840-DK, Espressif ESP32, …)
By integrating the library in your own app or IoT device, leveraging some of
the examples included in the project, you will be able to start building your
own communicating applications and services.
