Battle-tested Bluetooth with rock-solid reliability
Unstable C++17 Code Size Impact: 1.5 to 2 megabytes
This module is still under construction. There is no public API yet. Please contact the Pigweed team if you are interested in using this module.
pw_bluetooth_sapphire module provides a dual-mode Bluetooth Host stack
that will implement the pw_bluetooth APIs. Sapphire originated as
the Fuchsia operating system’s Bluetooth stack and is used in production. The
Sapphire Host stack has been migrated into the Pigweed project for use in
embedded projects. However, as it was not written in an embedded context, there
is a lot of work to be done to optimize memory usage.
Why use Sapphire?
Open source, unlike vendor Bluetooth stacks. This makes debugging and fixing issues much easier!
Integrated with Pigweed. Logs, asserts, randomness, time, async, strings, and more are all using Pigweed modules.
Excellent test coverage, unlike most Bluetooth stacks. This means fewer bugs and greater maintainability.
Certified. Sapphire was certified by the Bluetooth SIG after passing all conformance tests.
A great API. Coming 2024. See pw_bluetooth.
Implement pw_bluetooth APIs
