# winrt-Windows.Devices.Bluetooth.Advertisement — Python projection of Windows Runtime (WinRT) APIs

License: permissive · Maintenance: aging · Downloads: 210.3K/mo

## What it is and what it does

This package is a Python projection of the Windows Runtime (WinRT) Bluetooth.Advertisement API, allowing Python code running on Windows to interact with Bluetooth Low Energy (BLE) advertisement scanning and device discovery at the OS level. It is part of the modular PyWinRT ecosystem, where each Windows SDK namespace is published as a separate package; this one specifically exposes the advertisement-related Bluetooth functionality.

The package is Windows-only and requires Python 3.9 or later. It depends on winrt-runtime and is distributed as compiled wheels for multiple Windows architectures (32-bit, 64-bit, ARM64) and Python versions (3.9–3.14). It is typically used alongside other winrt-* packages to build applications that need low-level hardware access—such as BLE device scanning, filtering, and monitoring—directly from Python without wrapping native C++ code.

Use it for:

- Scan for nearby Bluetooth Low Energy devices and read their advertisement data on Windows
- Build a Python application that monitors BLE device presence or signal strength in real time
- Integrate Bluetooth hardware discovery into a Windows desktop or IoT application written in Python
- Access raw BLE advertisement payloads for custom protocol parsing or device identification

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides Python bindings to access Windows Runtime Bluetooth advertisement APIs directly from Python on Windows.

Yes, if you are on Windows and need to access Bluetooth advertisement APIs from Python. The package is permissively licensed (MIT), has no known vulnerabilities, and covers Python versions through 3.14. However, maintenance is aging (last release June 2025, last commit December 2025); verify that the API surface and stability meet your requirements before committing to it for production use. Not usable on non-Windows platforms.

## Install

pip install winrt-windows-devices-bluetooth-advertisement
uv add winrt-windows-devices-bluetooth-advertisement
poetry add winrt-windows-devices-bluetooth-advertisement

## Installing winrt-Windows.Devices.Bluetooth.Advertisement

Before you install: Medium friction: platform-specific wheels for Windows only (32-bit, 64-bit, ARM64) across Python 3.9–3.14. Requires winrt-runtime as a runtime dependency. Last commit December 2025 with aging maintenance status, though no recent breaking changes evident.

License in practice: MIT license permits commercial and private use with minimal restrictions; attribution required.

Quickstart:

pip install winrt-windows-devices-bluetooth-advertisement

from winrt.windows.devices.bluetooth.advertisement import BluetoothLEAdvertisementWatcher

watcher = BluetoothLEAdvertisementWatcher()
# Configure and start watching for BLE advertisements

Windows operating system required; wheels available only for Windows (win32, win_amd64, win_arm64). Python 3.9 or later.

Verify before relying:

- Whether this package is actively maintained or in maintenance-only mode given 'aging' status and 434 days since last release
- Real-world stability and API completeness for Bluetooth advertisement scanning workflows
- Whether additional WinRT namespace packages must be installed separately for typical use cases
