What is Sweetblue?

Sit back and let SweetBlue handle the nitty gritty issues of Bluetooth Smart development for Android and save months of development time.

Write code for one smart device and have the confidence that it will work on any other, saving you thousands in hardware and testing costs.

Know what’s going on under the hood at all times with comprehensive analytics, diagnostics, logging, and debugging facilities.

Unit test module for unit testing your app's Bluetooth logic
RxJava wrapper module
An API designed from the ground-up to be simple, predictable, and robust.
Transparent fallback, retry, and correction mechanisms for a multitude of failure conditions, both transient and permanent.
High-level constructs like transactions, state tracking, and polling that make common use cases a breeze to implement.
Full-coverage API documentation, sample projects, and support.

Full-coverage API documentation
Sample applications
Java with zero 3rd party API-level dependencies
Rich, queryable state tracking for simple UI integration
Automatic service discovery
Built-in polling and caching for RSSI and characteristic reads with change tracking to simulate notifications
Highly configurable scanning with continuous mode, min/max time limits, periodic bursts, advanced filtering, and more
Transactions for easily coordinating authentication handshakes, initialization and firmware updates
Undiscovery based on last time seen
Clean leakage of underlying native stack objects in case of emergency
Internal priority job queue that ensures serialization of all operations
Optimal coordination of the Bluetooth® low energy stack when connected to multiple devices

Detection, and correction of dozens of Bluetooth® low energy failure conditions
Numerous manufacturer-specific workarounds
Transparent retries for transient failure conditions
Distills dozens of lines of boilerplate, booby-trapped, native API usages into single method calls
Transparently falls back to Bluetooth® Classic for certain Bluetooth® low energy failure conditions
On-the-fly configurable reconnection loops started automatically when random disconnects occur
One convenient method to completely unwind and reset the Bluetooth stack
Verbose logging, runtime analytics and detailed warning and error reporting
Source code for the SweetBlue Toolbox app
Bluetooth 5 support (including the high-speed, and long range features)
