Mi arduino MKR1000 deja de enviar datos a thingspeak

Hola,

Tengo 2 arduinos MKR1000, el 1 y 2. El MKR1000 1 envía datos en un canal y 4 campos y me funciona bien. Entonces configuro el otro MKR1000 2 en el mismo canal pero en 4 campos diferentes y entonces éste último me deja de funcionar, sólo recibo 2 mensajes. Y cuando vuelvo a poner el MkR1000 1 ya sólo recibo también 2 mensajes.Thingspeak bloquea alguna MAC por algún motivo?

Muchas gracias.

Un saludo,

Sofía

We recommend using one channel for each device. There is a 15 second minimum between posting to a channel for the free license, so the devices are likely colliding and causing your data to be lost. Both devices can simultaneously post to separate channels.

If you want both devices to be visible in the same channel, you can create a derived channel with custom visualizations that scrape both channels and show the data. Or you could add a visualization for channel A that reads from channel B and displays the data there.

Thank you for your answer. I have also try to do this but I can not longer connect to thingspeak. I only receive 2 messages and then seems that my device is blocked. I have also try to delete the complete channel and to create a new one with only one device but I have the same problem, I receive only 2 messages. Do you know why is that? Thank you very much.

Do you mean you can only post or write two messages or you can only receive two messages from ThingSpeak when you try to read data?

My guess is that you are posting two fast. Can you share a code snippet so we can have a look at how you are writing or reading?

I mean that I can only send to thingspeak 2 messages after that I get and error and I can not send it.

I am not posting to fast because I am sending a message every 1 minute. Here you can see the code:

#include <SPI.h>

#include <WiFi101.h>

//Termopares

#include "max6675.h"

#include <TemperatureZero.h>

TemperatureZero TempZero = TemperatureZero();

char ssid[] = "****************";

char pass[] = "***************";

int status = WL_IDLE_STATUS;

// Initialize the Wifi client library

WiFiClient client;

// ThingSpeak Settings

char server[] = "api.thingspeak.com";

String writeAPIKey = "*******";

unsigned long lastConnectionTime = 0; // track the last connection time

const unsigned long postingInterval = 60L * 1000L; // post data every 60 seconds

//Termopares

int ktcSO = 8;

int ktcCS1 = 9; // chip select primer MAX6675

int ktcCLK = 10;

int ktcCS2 = 7; // chip select segundo MAX6675

int ktcCS3 = 6; // chip select tercer MAX6675

int ktcCS4 = 5; // chip select tercer MAX6675

int ktcCS5 = 4; // chip select tercer MAX6675

int ktcCS6 = 3; // chip select tercer MAX6675

MAX6675 ktc1(ktcCLK, ktcCS1, ktcSO);

MAX6675 ktc2(ktcCLK, ktcCS2, ktcSO);

MAX6675 ktc3(ktcCLK, ktcCS3, ktcSO);

MAX6675 ktc4(ktcCLK, ktcCS4, ktcSO);

MAX6675 ktc5(ktcCLK, ktcCS5, ktcSO);

}

// close any connection before sending a new request
