安装和示例
linux下安装
sudo apt-get install python-pip libglib2.0-dev
sudo pip install bluepy
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

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。

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