python 接收藍牙網關代碼（已解決）

這是mqtt的代碼  可以爲後面寫http通信的數據解析做參考 

完全可以測通的（是因爲防火牆的問題）

原因：開啓了防火牆在本地是可以測通的  外面的機器是訪問不了我的電腦的

解決辦法：關閉防火牆就可以了

輸入：

import time
import paho.mqtt.client as mqtt
import msgpack

def on_subscribe(mosq, obj, mid, granted_qos):
    print("Subscribed: " + str(mid))

def on_message(mosq, obj, msg):
    for d in msgpack.unpackb(msg.payload)[b'devices']:
        print("=============================================")
        # adv type
        print( "type:", ord(d[0]))
        print( "mac:{:02X}{:02X}{:02X}{:02X}{:02X}{:02X}".format(ord(d[1]), ord(d[2]), ord(d[3]), ord(d[4]), ord(d[5]), ord(d[6])))
        print( "rssi:", ord(d[7]) - 256)
        hex_chars = map(hex,map(ord,d))
        del hex_chars[:8]
        print( "adv:", hex_chars)

def on_connect(mosq, obj,flags, rc):
    print("Connected with result code "+str(rc))
    mqttc.subscribe("hello", 0)
    print("Connected")
    

mqttc = mqtt.Client()
mqttc.on_connect = on_connect
mqttc.on_subscribe = on_subscribe
mqttc.on_message = on_message
mqttc.connect("10.33.4.31", 60000, 60)
mqttc.loop_forever()

輸出：
