Bluetooth Low Energy platform Agnostic Klient
Project description
bleak
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.
Be warned: Bleak is still in an early state of implementation.
Installation
$ pip install bleak
Features
Supports Windows 10, version 16299 (Fall Creators Update) or greater
Supports Linux distributions with BlueZ >= 5.43
Plans on macOS support via Core Bluetooth API (see develop branch for progress)
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:
import asyncio
from bleak import discover
async def run():
devices = await discover()
for d in devices:
print(d)
loop = asyncio.get_event_loop()
loop.run_until_complete(run())
Connect to a Bluetooth device and read its model number:
import asyncio
from bleak import BleakClient
address = "24:71:89:cc:09:05"
MODEL_NBR_UUID = "00002a24-0000-1000-8000-00805f9b34fb"
async def run(address, loop):
async with BleakClient(address, loop=loop) as client:
model_number = await client.read_gatt_char(MODEL_NBR_UUID)
print("Model Number: {0}".format("".join(map(chr, model_number))))
loop = asyncio.get_event_loop()
loop.run_until_complete(run(address, loop))
