ASCII命令發送到藍牙設備使用Python接收數據

我想從樹莓派發送十六進制cmd（0X2A，0X0A，0X58）到我的另一個藍牙接口設備（Arduino）接收傳感器data.when我使用的服務器。發送（0X2A，0X0A，0X58）。它不工作。所以如何發送請求cmd來接收來自藍牙的數據。我已經配對了我的藍牙設備。ASCII命令發送到藍牙設備使用Python接收數據

from bluetooth import 

server_sock=BluetoothSocket(RFCOMM) 
server_sock.bind(("",PORT_ANY)) 
server_sock.listen(1) 

port = server_sock.getsockname()[1] 

uuid = "94f39d29-7d6d-437d-973b-fba39e49d4ee" 

advertise_service(server_sock, "SampleServer", 
        service_id = uuid, 
        service_classes = [ uuid, SERIAL_PORT_CLASS ], 
        profiles = [ SERIAL_PORT_PROFILE ], 
#     protocols = [ OBEX_UUID ] 
        ) 

print "Waiting for connection on RFCOMM channel %d" % port 

client_sock, client_info = server_sock.accept() 
print "Accepted connection from ", client_info 

try: 
    while True: 
     server.send(0X2A,0X0A,0X58) 
     data = client_sock.recv(1024) 
     if len(data) == 0: break 
     print "received [%s]" % data 
except IOError: 
    pass 

print "disconnected" 
client_sock.close()

您的意思是錯過關閉正在導入1號線的東西？ – Goralight

請閱讀[「我應該怎麼做當有人回答我的問題？」]（http://stackoverflow.com/help/someone-answers）。 – thewaywewere

您可以更改發送串行數據，

server.send('\x2A\x0A\x58')或
server.send('2A0A58'.decode("hex"))
