• (Python) Fixed GIL issues introduced in v0.10.2.

[0.10.2] - 2025-06-20

[0.10.1] - 2025-05-30

Notes

• The Rust bindings have undergone a major rewrite of their API, towards a more idiomatic Rust style and stream-based API.
• iOS and Android do not support powering on and off the adapter. Calling these methods will not have any effect on the adapter.
• Linux does have support for powering on and off the adapter, but further architecture changes are needed to properly expose this.
• Callbacks for power on and off events are currently only supported on Windows.
• Retrieving connected peripherals is currently only supported on Windows. More backends coming soon.

Added

• Functions for powering adapters on, off and querying their power state.
• Callbacks to monitor adapter power on and off events.
• (Windows) Added support for powering adapters on and off.
• (Windows) Added support for retrieving paired peripherals.
• (Windows) Added support for retrieving connected peripherals.
• (Python) Exposed the Adapter::power_on(), Adapter::power_off() and Adapter::is_powered() methods.
• (Android) Calls to Java methods are now checked for exceptions.
• (Java) Calls to Java methods are now checked for exceptions.
• (Android) Added support for requesting a specific connection priority via configuration. (Thanks Nicole S.!)
• (MacOS) Added support for powering adapters on and off.
• (Linux) Added configurable connection and disconnection timeouts. (Thanks Kober Engineering!)

Changed

• (Windows) Calls to the WinRT backend are now executed in a separate MTA apartment by default.
• (Android) Migrated to using the simplejni library for JNI bindings.
• API CHANGE: (Rust) Migrated to streams for scan and connection events.
• API CHANGE: (Rust) Migrated to streams for peripheral notifications and indications.

Fixed

• (Android) Fixed a bug where the GATT object would not be closed if a connection was lost. (Thanks Nicole S.!)
• (Rust) Fixed a race condition in the Rust bindings that would cause a crash if the adapter was deleted while a callback was in progress.
• Added missing operating system definitions for utils.
• (Linux) Use steady_clock instead of system_clock for timeout calculations. (Thanks Kober Engineering!)

Removed

• Source code of the simpleble-bridge project in favor of simpledroidbridge.

[0.9.1] - 2025-04-24

Important:

• In the near future we will deprecate the simpleble-c target in favor of simplecble, which will be a drop-in replacement for the existing C bindings.
• The simpleble-bridge project has been renamed to simpledroidbridge and can be found in the root directory of the repository.

Added

• (Android) Implemented the following API functions:
  • Adapter::scan_get_results()
  • Adapter::get_paired_peripherals()
  • Peripheral::rssi()
  • Peripheral::tx_power()
  • Peripheral::is_connectable()
  • Peripheral::is_paired()
  • Peripheral::manufacturer_data()
  • Peripheral::advertised_services()
• (Java) Early preview of Java bindings.
• Configuration class to control the behavior of SimpleBLE internals as well as experimental features.
• SimpleCBLE: Moved SimpleBLE C bindings into a separate library.

Changed

• Adapter::identifier() method is non-const, as underlying const conditions can't be guaranteed.
• (Android) Callback functions are not handled on a separate, dedicated thread.
• (Windows) (Experimental) Calls to the WinRT backend can now be executed in a separate MTA apartment via feature flag.
• (Android) The simpleble-bridge project has been renamed to simpledroidbridge.
• Upgraded fmt dependency to version 11.1.4 and vendorized into the repository.

Fixed

• (Android) Some potential race conditions in the Android backend.
• (Android) Fixed handling of null objects.
• (Android) Peripheral::address_type() and Peripheral::unpair() had to be removed due to API level limitations.
• (Android) Potential duplicate callback invocations on builds with newer Android API levels.

[0.9.0] - 2025-01-20
