环境

win10 python3.8

网上方式尝试

首先网上大多数都是使用的pybluez这个库，但我安装时总出现问题，已经安装的有VS C++环境和win10SDK

 

我的方式

经历过上面的错误，开始查看这个库，发现GitHub上有另外一个工程pybluez2，并且更新的版本更高，于是尝试，安装成功

pip地址

https://pypi.org/project/pybluez2/

github地址

使用方法

可直接查看github的例子，非常好用

import bluetooth
print(bluetooth.read_local_bdaddr())
server_sock = bluetooth.BluetoothSocket(bluetooth.RFCOMM)
server_sock.bind(("", bluetooth.PORT_ANY))
server_sock.listen(1)
port = server_sock.getsockname()[1]
uuid = "94f39d29-7d6d-437d-973b-fba39e49d4ee"
bluetooth.advertise_service(server_sock, "SampleServer", service_id=uuid,
                            service_classes=[uuid, bluetooth.SERIAL_PORT_CLASS],
                            profiles=[bluetooth.SERIAL_PORT_PROFILE],
                            # protocols=[bluetooth.OBEX_UUID]
                            )
print("Waiting for connection on RFCOMM channel", port)
client_sock, client_info = server_sock.accept()
print("Accepted connection from", client_info)
try:
    while True:
        data = client_sock.recv(1024)
        if not data:
            break
        print("Received", data)
except OSError:
    pass
print("Disconnected.")
client_sock.close()
server_sock.close()
print("All done.")

其他发现

python3.9版本 win已经支持蓝牙

https://docs.python.org/3.9/library/socket.html#module-socket

换成python3.9.4没有成功
