It abstracts away platform differences using native APIs on Windows, macOS, Linux, and Android, so you write one async/await-based client that works everywhere. The library handles device discovery, GATT characteristic reading and writing, and subscription to notifications from BLE sensors and peripherals.\n\nTypical use involves discovering nearby BLE devices, connecting to a specific device by address, and then reading or writing GATT characteristics identified by UUID. All operations are async, making it suitable for applications that need to manage multiple concurrent BLE connections or integrate BLE communication into larger async event loops. The library depends on platform-specific system libraries and Python 3.10 or later.","worth_installing":"Yes. Bleak is actively maintained, widely used (top 5000 PyPI), has no known vulnerabilities, and offers a clean async API for BLE communication across major platforms. Install it if you need to communicate with BLE devices from Python. The main gotcha is platform-specific system dependencies and the Python 3.10 or later requirement\u2014verify those match your environment before committing."},"id":"bleak","links":{"html":"https://skillfed.io/packages/bleak","md":"https://skillfed.io/packages/bleak.md","pypi":"https://pypi.org/project/bleak/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-05-02","license_spdx":"MIT","license_treatment":"permissive","name":"bleak","python_support":"supports_current","summary":"Bluetooth Low Energy platform Agnostic Klient"},"popularity":{"monthly_downloads":2131283,"position":3268,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"3.0.2"}
