bit MQTT

ObloqMqttPublish.py 发送数据示例

from microbit import *
import Obloq

SERVER = "iot.dfrobot.com.cn"
PORT = "1883"
SSID = "dfrobotYanfa"  # 修改为wifi名称，不要使用中文
PASSWORD = "hidfrobot" # 修改为wifi密码
IOT_ID = "SyWPtKo_Kz"  # 修改为IOT_ID
IOT_PWD = "HJfwKFjdtz" # 修改为IOT_PWD
IOT_TOPIC1 = "BysFYi_FM" # 修改为IOT_TOPIC1
IOT_TOPIC2 = "SkmigyM5z" # 修改为IOT_TOPIC2

uart.init(baudrate=9600, bits=8, parity=None, stop=1, tx=pin2, rx=pin1)

def ConnectWifi():    
    while Obloq.connectWifi(SSID,PASSWORD,10000) != True:
        display.show(".")
    display.scroll(Obloq.ifconfig()) 
def event(e,param):
    if e == "MqttConneted":#MQTT连接成功
        display.scroll("OK")    
ConnectWifi()

#初始化MQTT的配置
Obloq.mqttConfig(event,SERVER,PORT)

#连接MQTT
Obloq.connectMqtt(IOT_ID,IOT_PWD)
while True:
    sleep(10000)
    #向服务器的IOT_TOPIC1发送hello
    Obloq.publish(IOT_TOPIC1,"hello")
    sleep(10000)
    Obloq.publish(IOT_TOPIC2,"HELLO")

ObloqMqttSubscribe.py 接收数据示例

from microbit import *
import Obloq

SERVER= "iot.dfrobot.com.cn"
PORT= "1883"
SSID= "dfrobotYanfa"
PASSWORD = "hidfrobot"
IOT_ID = "SyWPtKo_Kz"
IOT_PWD = "HJfwKFjdtz"
IOT_TOPIC1 = "BysFYi_FM"
IOT_TOPIC2 = "SkmigyM5z"

uart.init(baudrate=9600, bits=8, parity=None, stop=1, tx=pin2, rx=pin1)

def ConnectWifi():    
    while Obloq.connectWifi(SSID,PASSWORD,10000) != True:
        display.show(".")
    display.scroll(Obloq.ifconfig()) 
    
#设置MQTT的回调函数 
def event(e,param):
    if e == IOT_TOPIC1:#收到了订阅的topic的信息
        display.scroll(param)
    if e == IOT_TOPIC2:
        display.scroll(param)
    if e == "MqttConneted":#MQTT连接成功
        display.scroll("OK")
    if e == "SubOk":#订阅成功        
        display.scroll("OK")        
ConnectWifi()

#初始化MQTT的配置
Obloq.mqttConfig(event,SERVER,PORT)

#连接MQTT
Obloq.connectMqtt(IOT_ID,IOT_PWD)
sleep(300)
Obloq.subscribe(IOT_TOPIC1)#订阅Topoic1
sleep(300)
Obloq.subscribe(IOT_TOPIC2)#订阅Topoic2
while True:
    pass
