python连接有PIN的蓝牙，搜索成功但连接不上

连接有PIN的蓝牙设备需要在代码中设置相应的PIN码进行连接，可以参考以下代码：

import bluetooth

target_name = "Your Bluetooth Device Name"
target_address = None

nearby_devices = bluetooth.discover_devices()

for bdaddr in nearby_devices:
    if target_name == bluetooth.lookup_name(bdaddr):
        target_address = bdaddr
        break

if target_address is not None:
    port = 1
    password = "Your PIN"
    sock = bluetooth.BluetoothSocket(bluetooth.RFCOMM)
    sock.connect((target_address, port))
    sock.send(password)
    sock.close()
    print("Connected to", target_name)
else:
    print("Could not find target Bluetooth device nearby")

在代码中修改`target_name`为你的蓝牙设备的名称，`password`为连接密码即可。如果连接成功，将会输出"Connected to Your Bluetooth Device Name"的信息。如果仍然无法连接，建议检查一下设备的PIN码是否正确。
