Hi, I am using arduino IOT cloud for my project. I am currently using 2 arduino mkr 1010 devices and have defined a project for each one.
The idea is to use the 2nd one as a slave, having connected an env shield which measures variables such as temperature, humidity, etc. My 1st device is used as a master which displays these variables in an lcd display screen. The variables defined in the 1st project are linked with the ones in the 2nd one via iot cloud.
Once I run the project it works propperly for the first 5 seconds but after that an error is shown in my 2nd project serial port "ArduinoIoTCloudTCP::handle_Disconnect MQTT client connection lost" and the sensor values no longer upload to the 2nd project.
I have an idea of what might be causing the problem, arduino iot cloud refresh time might be too frequent, I tried to change the refreshing time of the values but this doens't solve the error. Does anyone have experience working with arduino iot cloud ?
1st project code:
#include <Arduino_MKRENV.h>
#include "thingProperties.h"
int muestras;
void setup() {
// Initialize serial and wait for port to open:
Serial.begin(9600);
// This delay gives the chance to wait for a Serial Monitor without blocking if none is found
delay(1500);
// Defined in thingProperties.h
initProperties();
// Connect to Arduino IoT Cloud
ArduinoCloud.begin(ArduinoIoTPreferredConnection);
/*

related to the state of network and IoT Cloud connection and errors
the higher number the more granular information you’ll get.
The default is 0 (only errors).
Maximum is 4
*/
setDebugMessageLevel(2);
ArduinoCloud.printDebugInfo();
if (!ENV.begin()) {
Serial.println("Failed to initialize MKR ENV shield!");
while (1);
}
}
void loop() {
ArduinoCloud.update();

mV = map(muestras, 0, 1024, 0, 5000);

humidity = ENV.readHumidity();
