[SOLVED] Blynk Project keeps restarting

[stevelondon]

Hi all.

Can anyone see why my project keeps halting and restarting whenever void save changes() is called?

The void savechanges is as follows…

void savechanges()
{
  char bufTime1[20];
  sprintf(bufTime1, "%02d:%02d", doser1timeH, doser1timeM);
  char bufTime2[20];
  sprintf(bufTime2, "%02d:%02d", doser2timeH, doser2timeM);
  char bufTime3[20];
  sprintf(bufTime3, "%02d:%02d", doser3timeH, doser3timeM);
  char bufTime4[20];
  sprintf(bufTime4, "%02d:%02d", doser4timeH, doser4timeM);

  String body = String("Alkalinty will dose ") + doser1amount + "ml at " + bufTime1; + " Calcium will dose "+ doser2amount + "ml at " + bufTime2 + " Magnesium will dose "+ doser3amount + "ml at " + bufTime3 + " Reef Nutrition will dose "+ doser4amount + "ml at " + bufTime4;
  Blynk.notify(body);
  
  Blynk.virtualWrite(V13, 0);
  Serial.println("Changes saved");
}

It stops and restarts after the Blynk.notify line. I get the Blynk push message on my phone, but then obvs it stops. Can anyone see why and how I can fix it?

If you need the full code let me know, but its quite long.

Thanks in advance, Steve.

Fixed it myself. Leaving the post up for info.

I didn’t realise the message was so long so had to add the following code at the top to extend the amount that could be sent…

#define BLYNK_MAX_SENDBYTES 256

Works fine now.

What are you making? The reason I ask is I am writing the code to make an Alkalinity controller similar to the Alkatronic

Hi mate. That’s exactly what I’m making. However it is a four pump unit.

Ahh a doser, I made a 6 doser for myself for my aquarium
