安裝和示例
linux下安裝
sudo apt-get install python-pip libglib2.0-dev
sudo pip install bluepy
官方示例
importbtleclassmydelegate(btle.defaultdelegate):def __init__(self, params):
btle.defaultdelegate.__init__(self)#... initialise here
defhandlenotification(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 --------
whiletrue:if p.waitfornotifications(1.0):#handlenotification() was called
continue
print "waiting..."
#perhaps do something else here
藍芽通訊模組pybluez的使用
選擇藍芽通訊物件
importbluetooth
target_name= "my device"target_address=none
nearby_devices=bluetooth.discover_devices()for bdaddr innearby_devices:if target_name ==bluetooth.lookup_name( bdaddr ):
target_address=bdaddrbreak
if target_address is notnone:print("found target bluetooth device with address", target_address)else:print("could not find target bluetooth device nearby")
查詢裝置服務
importbluetooth
nearby_devices= bluetooth.discover_devices(lookup_names=true)for addr, name innearby_devices:print("%s - %s" %(addr, name))
services= bluetooth.find_service(address=addr)for svc inservices: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("")
通過rfcomm方式進行通訊
採用類似於socket程式設計模型的方式進行藍芽通訊的程式設計
1.伺服器端程式
importbluetooth
server_sock=bluetooth.bluetoothsocket( bluetooth.rfcomm )
port= 1server_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. 客戶端程式
importbluetooth
bd_addr= "01:23:45:67:89:ab"port= 1sock=bluetooth.bluetoothsocket( bluetooth.rfcomm )
sock.connect((bd_addr, port))
sock.send("hello!!")
sock.close()
通過l2cap方式進行通訊
l2cap的sockets方式幾乎等同於rfcomm的sockets方式，唯一的不同是通過l2cap的方式，並且埠是0x1001到0x8fff之間的奇數埠。預設的連線可以傳送的可靠報文是672個位元組。
1.伺服器端程式
importbluetooth
server_sock=bluetooth.bluetoothsocket( bluetooth.l2cap )
port= 0x1001server_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.客戶端程式
importbluetooth
sock=bluetooth.bluetoothsocket(bluetooth.l2cap)
bd_addr= "01:23:45:67:89:ab"port= 0x1001sock.connect((bd_addr, port))
sock.send("hello!!")
sock.close()
調整mtu大小
l2cap_sock =bluetooth.bluetoothsocket( bluetooth.l2cap )#connect the socketbluetooth.set_l2cap_mtu( l2cap_sock,65535 )

Mac上同時安裝python3和python2
系統 mac 已安裝環境 anaconda3，python3 由於在平時的專案中，經常由於各種python庫的版本不匹配的問題，導致python2和python3的執行環境無法相容。因此我們可以在上述已安裝環境的基礎上，再安裝python2。具體步驟非常簡單，參考下面。先檢查當前環境為python3...
