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
$ pip install bleak

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:
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:
import asyncio
from bleak import BleakClient
address = "24:71:89:cc:09:05"
MODEL_NBR_UUID = "2A24"
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))
