本文主要是介绍Windows下 python pybluez 安装使用记录，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

前言

参考文章：Python蓝牙开发库–pybluez详解
系统：Windows10 企业版
IDE：pycharm2020
python版本：3.6.13 （注意我使用的版本）
环境创建： Anaconda3
电脑：台式机 外接蓝牙

pybluez github地址：https://github.com/pybluez/pybluez
官方文档：https://pybluez.readthedocs.io/en/latest/api/index.html#classes

安装

据参考博文说，3.6及以下版本可以正常安装，3.6以上就会报错Windows SDK相关错误（注意版本，实测过3.8版本 安装会报Windows sdk相关错误，解决方案网上也有很多，装sdk后修改相关参数，这里不再赘述），所以本文采用了py3.6
参考命令：pip install pybluez

测试

部分例程跑不起来，就没有列举

搜索蓝牙设备

参考文章：Python蓝牙开发库–pybluez详解

#!/usr/bin/env python
# --*--coding=utf-8--*--
# pip install pybluez

import time
from bluetooth import *

#列表，用于存放已搜索过的蓝牙名称
alreadyFound = []

#搜索蓝牙
def findDevs():
    foundDevs = discover_devices(lookup_names=True)
    # 循环遍历,如果在列表中存在的就不打印
    for (addr,name) in foundDevs:
        if addr not in alreadyFound:
            print("[*]蓝牙设备:" + str(name))
            print("[+]蓝牙MAC:" + str(addr))
            # 新增的设备mac地址定到列表中,用于循环搜索时过滤已打印的设备
            alreadyFound.append(addr)

# 循环执行,每5秒执行一次
while True:
    findDevs()
    time.sleep(1)

读取本地蓝牙设备地址 read-local-bdaddr.py

官方例程：pybluez/examples/advanced/read-local-bdaddr.py

#!/usr/bin/env python3
"""PyBluez advanced example read-local-bdaddr.py
Read the local Bluetooth device address
"""

import bluetooth

if __name__ == "__main__":
    print(bluetooth.read_local_bdaddr())

执行简单的设备查询，然后是每个设备的远程名称请求 发现的设备

官方例程：pybluez/examples/simple/inquiry.py

#!/usr/bin/env python3
"""PyBluez simple example inquiry.py
Performs a simple device inquiry followed by a remote name request of each
discovered device
Author: Albert Huang <albert@csail.mit.edu>
$Id: inquiry.py 401 2006-05-05 19:07:48Z albert $
"""

import bluetooth

print("Performing inquiry...")

nearby_devices = bluetooth.discover_devices(duration=8, lookup_names=True,
                                            flush_cache=True, lookup_class=False)

print("Found {} devices".format(len(nearby_devices)))

for addr, name in nearby_devices:
    try:
        print("   {} - {}".format(addr, name))
    except UnicodeEncodeError:
        print("   {} - {}".format(addr, name.encode("utf-8", "replace")))

使用RFCOMM套接字的服务器应用程序的简单演示 rfcomm-server.py

官方例程：pybluez/examples/simple/rfcomm-server.py

#!/usr/bin/env python3
"""PyBluez simple example rfcomm-server.py
Simple demonstration of a server application that uses RFCOMM sockets.
Author: Albert Huang <albert@csail.mit.edu>
$Id: rfcomm-server.py 518 2007-08-10 07:20:07Z albert $
"""

import bluetooth

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.")

ps：rfcomm-client.py 运行报错。。。
