Python BLE 发现所有 UUID 特征

Question

到目前为止，这段代码正在向我返回服务的 UUID。但是我里面有几个特征，我能查到他们的UUID吗？

import asyncio
from bleak import BleakScanner

async def run():
    devices = await BleakScanner.discover()
    for d in devices:
        print(d.metadata)
            
loop = asyncio.get_event_loop()
loop.run_until_complete(run())

Answer 1

discover只是从设备获取广告信息。在那个阶段，您的客户将不会解析服务并了解其特征。该信息仅在客户端连接到设备后可用。浏览文档，您似乎通过 get_services 获得了所需的信息，因为 returns GATT 服务树：
