bleak: Bluez backend: Can't connect to device returned from detection callback

• bleak version: 0.10.0
• Python version: 3.7.3
• Operating System: raspbian buster
• BlueZ version (bluetoothctl -v) in case of Linux: 5.50

Description

“path” isn’t set in the device in the detection callback and crashes if you try and use the code in the following way:

import asyncio
from bleak import BleakScanner, BleakClient
from bleak.backends.device import BLEDevice
from bleak.backends.scanner import AdvertisementData
import logging

logging.basicConfig()

search_name = "Mo03F4000B"

class Test:
    def __init__(self):
        self.bt_client = None
        loop = asyncio.get_event_loop()
        loop.run_until_complete(self.run())
        
    def simple_callback(self, device: BLEDevice, advertisement_data: AdvertisementData):
        if search_name in device.name:
            print(f"Found {device}")
            self.bt_client = device
        
    async def run(self):
        scanner = BleakScanner()
        scanner.register_detection_callback(self.simple_callback)

        while self.bt_client is None:
            print(self.bt_client)
            await scanner.start()
            await asyncio.sleep(1.0)
            await scanner.stop()
        print(f"Connecting to {self.bt_client}")
        async with BleakClient(self.bt_client) as client:
            svcs = await client.get_services()
            print(f"{svcs}")

t = Test()

Output:
