[RobotDyn WIFI D1 R2]Login timeout

Hi. I have RobotDyn WIFI D1 R2. I have Error with connect to server. First Connection work, but only first. Next are Login Timeout Error. This is my Code

#define BLYNK_PRINT Serial    // Comment this out to disable prints and save space
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <SimpleTimer.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "MYTOKEN"; //insert here your token generated by Blynk

float temp;
int tempPin = 17; // ADC pin

SimpleTimer timer;

void setup()
  Serial.begin(9600); // See the connection status in Serial Monitor
  Blynk.begin(auth, "MY SSID", "MYPASS"); //insert here your SSID and password

  // Setup a function to be called every second
  timer.setInterval(5000L, sendUptime);

// This function sends Arduino's up time every second to Virtual Pin (5).
// In the app, Widget's reading frequency should be set to PUSH. This means
// that you define how often to send data to Blynk App.
void sendUptime()
  // You can send any value at any time.
  // Please don't send more that 10 values per second.
  Blynk.virtualWrite(10, temp); // virtual pin 10

void loop()
  Blynk.run(); // Initiates Blynk
  timer.run(); // Initiates SimpleTimer
 // delay(1000);
   temp = analogRead(tempPin);
   temp = temp * 0.09765625; // costance (1/1024*100)

Try leaving the loop as “free” as possible, take below part and leave it into your “senduptime” function.

Thanks for reply. Unfortunately don’t work. Any other ideas?

Ok I spent one more hour and partitialy works. On Phone i saw messages “Device was dissconected” And LOG.

@Marcin_Zasuwa in your sketch you have a comment that the ADC pin is 17.

Are you sure it is 17 and not A0?

Awesome. I copy and paste code. After I changed to “A0” it worked, but it disconnect less. Why? I use 160MHz and Code like up :smiley:
