Python 蓝牙通信模块pybluez Win7

今天学习windows下的蓝牙控制，安装pybluez

pip install pybluez

安装很顺利，没有遇见网上关于sdk之类的问题，可能是我的机子已经安装了vs各运行库的原因吧

使用库只需要import bluetooth即可，但我这里出现了

AtributeError: attribute '__doc__' of 'instancemethod' objects is not writable

解决方式是重新安装，指定版本为0.22

pip install pybluez==0.22

使用方式：

通过名字查找蓝牙设备

import bluetooth

def findDevByName(name)
	devices = bluetooth.discover_devices()
	devAddr=""
	for addr in devices:
    	if bluetooth.lookup_name( addr)==name:
        	devAddr = addr
        	break
    return devAddr

遍历所有设备服务

import bluetooth
 
devices = bluetooth.discover_devices(lookup_names=True)
for addr, name in devices:
    print("  %s - %s" % (addr, name))
    services = bluetooth.find_service(address=addr)
    for service in services:
        print("Service Name: %s"    % service["name"])
        print("    Host:        %s" % service["host"])
        print("    Description: %s" % service["description"])
        print("    Provided By: %s" % service["provider"])
        print("    Protocol:    %s" % service["protocol"])
        print("    channel/PSM: %s" % service["port"])
        print("    svc classes: %s "% service["service-classes"])
        print("    profiles:    %s "% service["profiles"])
        print("    service id:  %s "% service["service-id"])

设备通信代码
设备通信分服务端和客户端

服务器端代码

import bluetooth
 
server_sock=bluetooth.BluetoothSocket( bluetooth.RFCOMM )
port = 1
server_sock.bind(("",port))
server_sock.listen(1)
client_sock,address = server_sock.accept()
print "Accepted connection from ",address
data = client_sock.recv(1024)
print "received [%s]" % data
client_sock.close()
server_sock.close()

客户端代码

import bluetooth
 
bd_addr = "01:23:45:67:89:AB"
port = 1
sock=bluetooth.BluetoothSocket( bluetooth.RFCOMM )
sock.connect((bd_addr, port))
sock.send("hello!!")
sock.close()

还有另一种方式是使用L2CAP方式，
区别只在端口的选择上，这里不再详述
