如何使用python套接字AF_bluetooth套接字广播蓝牙查询？

import bluetooth

sock = bluetooth.BluetoothSocket(bluetooth.RFCOMM)

sock.bind(("", bluetooth.PORT_ANY))

sock.listen(1)

local_address = sock.getsockname()[0]
local_port = sock.getsockname()[1]

bluetooth.advertise_service(sock, "BluetoothQuery", service_id=bluetooth.SERIAL_PORT_CLASS, profiles=[bluetooth.SERIAL_PORT_PROFILE])

client_sock, client_info = sock.accept()

data = client_sock.recv(1024)

# 在这里进行数据处理的逻辑

client_sock.close()
sock.close()
