Bleak is an acronym for Bluetooth Low Energy platform Agnostic Klient.
* Free software: MIT license
* Documentation: https://bleak.readthedocs.io.
Bleak is a GATT client software, capable of connecting to BLE devices
acting as GATT servers. It is designed to provide a asynchronous,
cross-platform Python API to connect and communicate with e.g. sensors.
Installation
------------
.. code-block:: bash
$ pip install bleak
Features
--------
* Supports Windows 10, version 16299 (Fall Creators Update) or greater
* Supports Linux distributions with BlueZ >= 5.43
* OS X/macOS support via Core Bluetooth API, from at least OS X version 10.11
* Android backend compatible with python-for-android
Bleak supports reading, writing and getting notifications from
GATT servers, as well as a function for discovering BLE devices.
Usage
-----
To discover Bluetooth devices that can be connected to:
.. code-block:: python
import asyncio
from bleak import BleakScanner
async def main():
devices = await BleakScanner.discover()
for d in devices:
print(d)
asyncio.run(main())
Connect to a Bluetooth device and read its model number:
.. code-block:: python
import asyncio
from bleak import BleakClient
address = "24:71:89:cc:09:05"
MODEL_NBR_UUID = "00002a24-0000-1000-8000-00805f9b34fb"
async def main(address):
async with BleakClient(address) as client:
model_number = await client.read_gatt_char(MODEL_NBR_UUID)
print("Model Number: {0}".format("".join(map(chr, model_number))))
asyncio.run(main(address))
DO NOT NAME YOUR SCRIPT ``bleak.py``! It will cause a circular import error.
See examples folder for more code, for instance example code for connecting to a
`TI SensorTag CC2650 <http://www.ti.com/ww/en/wireless_connectivity/sensortag/>`_
