Error sending payload. SiPy Sigfox. **SOLVED**



  • Hello, good day to all.

    I have done tests from the console sending data to Sigfox's Backend, however when I do it from the code it is blocked the moment it is sent:

    s.send(bytes(payload))
    

    And this is the code I use:

    import pycom
    import time, utime, machine, dht, socket
    from machine import Pin, Timer, WDT
    from network import Sigfox
    
    ID_ESTACION=2
    T_ESTACION=114 #114 es la R en DEC --- 99 es la C en DEC --- 97 es la A en DEC
    
    FlagWDT = 0 #Bandera del WDT
    #wdt = WDT(timeout=60000) #inicializamos WDT con tiempo de 1 minuto
    pycom.heartbeat(False) #Apagamos el led
    
    #Código para leer Temperatura y Humedad
    th = dht.DTH(Pin('P11', mode=Pin.OPEN_DRAIN),1)
    tem=0
    hum=0
    result=0
    cont=0
    #time.sleep(2)
    #result = th.read()
    def readTemHum():
        global tem, hum
        cont=0
        #time.sleep(2)
        result = th.read()
        while result.is_valid()==False:
            result = th.read()
        if result.is_valid():
            tem=result.temperature/1.0
            hum=result.humidity/1.0
            #print('Temperatura: {:3.2f}'.format(tem))
            #print('Humedad: {:3.2f}'.format(hum))
        else:
            tem=tem
            hum=hum
            #print('Temperatura: {:3.2f}'.format(tem))

        #separado = 0

        #print(valS)
        try:
            separado=valS.split("b'R")
            separado = separado[1].split("\\")
            separado = separado[0]
            last_value=int(separado)

        print("Valor a enviar: ",payload)
        print(type(payload[0]))
        sendsig(payload)

    while FlagWDT==0:

    time.sleep(2)
    #machine.deepsleep(588000) #duerme 9,8 min + 30 segundos que demora enviar el mensaje serían 10,30 min, equivalentes a 139.8 mensajes al día
    

    The payload that is sent is of this type:

    >>> print(payload)
    (2, 2, 183, 1, 38, 55, 114)
    >>>type(payload)
    <class 'tuple'>
    

    I've done the testing by sending this payload from the console and I have no problem, but when I load the code in SiPy, it crashes.

    I hope you can help me. Thank you and happy day.



  • Hi everyone.

    I want to tell you that I have already solved the problem. There is a conflict with the line in which I declare a Pin as output and the moment in which it is transmitted:

    Pin('P5', mode=Pin.OUT, value=1)
    

    What I did was change the pin to P13, this ended the problem and I was able to transmit without any inconvenience and see the data in the Sigfox Backend.:

    Pin('P13', mode=Pin.OUT, value=1)
    

    0_1504880078593_upload-1af3b981-1883-46c5-afa3-16dfe2bcb8ef



  • Ok, I've noticed that there is a compatibility problem between the UART read and the socket to send to the Sigfox network.

    I will try to solve it and then we will see.
