官方示例

import btle class MyDelegate(btle.DefaultDelegate): def __init__(self, params): btle.DefaultDelegate.__init__(self) # ... initialise here def handleNotification(self, cHandle, data): # ... perhaps check cHandle # ... process ‘data‘ # Initialisation ------- p = btle.Peripheral( address ) p.setDelegate( MyDelegate(params) ) # Setup to turn notifications on, e.g. # svc = p.getServiceByUUID( service_uuid ) # ch = svc.getCharacteristics( char_uuid )[0] # ch.write( setup_data ) # Main loop -------- while True: if p.waitForNotifications(1.0): # handleNotification() was called continue print "Waiting..." # Perhaps do something else here

蓝牙通信模块pybluez的使用

选择蓝牙通信对象

import bluetooth target_name = "My Device" 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: print("found target bluetooth device with address ", target_address) else: print("could not find target bluetooth device nearby")

查询设备服务

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

通过RFCOMM方式进行通信

采用类似于socket编程模型的方式进行蓝牙通信的编程

1.服务器端程序

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()

2. 客户端程序

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()

通过L2CAP方式进行通信

L2CAP的sockets方式几乎等同于RFCOMM的sockets方式，唯一的不同是通过L2CAP的方式，并且端口是0x1001到0x8FFF之间的奇数端口。默认的连接可以传送的可靠报文是672个字节。

1.服务器端程序

import bluetooth server_sock=bluetooth.BluetoothSocket( bluetooth.L2CAP ) port = 0x1001 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()

2.客户端程序

import bluetooth sock=bluetooth.BluetoothSocket(bluetooth.L2CAP) bd_addr = "01:23:45:67:89:AB" port = 0x1001 sock.connect((bd_addr, port)) sock.send("hello!!") sock.close()

调整MTU大小

l2cap_sock = bluetooth.BluetoothSocket( bluetooth.L2CAP ) # connect the socket bluetooth.set_l2cap_mtu( l2cap_sock, 65535 )
