MKR 1010 wifi goes offline after a few minutes (external powered)

Hi,

i ve seen some related topics concerning external powered MKR 1010 wifi, but even after trying to resolve this issue, my device keeps disconnecting after a few minutes.

  • powered 5V pin instead of Vin.
  • removed all serial statements in code.
  • upgraded to latest firmware version 1.5

So after doing this it does connect and send data. (previously not) but it disconnects after a while and it seems it doesnt try to go online again.

My test code is pretty simple

#include "thingProperties.h"
#define DHTPIN 7
#define DHTTYPE DHT11
DHT dht(DHTPIN, DHTTYPE);

void setup() {
  delay(1500); 

  initProperties();

  ArduinoCloud.begin(ArduinoIoTPreferredConnection);

  pinMode(LED_BUILTIN, OUTPUT);
  
  dht.begin();
}

void loop() {
  ArduinoCloud.update();

  digitalWrite(LED_BUILTIN, HIGH);  
  delay(1000);                      
  
  temperature = dht.readTemperature();
  humidity = dht.readHumidity();
  
  digitalWrite(LED_BUILTIN, LOW);   
  delay(1000);  
}

Anyone any idea what goes wrong ?

kind regards.

Can you try removing the delay(1000); inside your loop?

The usage of delays may interfere with the state machine, more details here
