Prefill table

Solved
1

Dear all, i need to prefill a table with some values but the following code fails to do this. The table remain empty.
I think because the write occours before the blynk.run().
Any help will be appreciated


/* Comment this out to disable prints and save space */
#define BLYNK_PRINT Serial
#define BLYNK_DEBUG

#include <ESP8266WiFi.h>
#include <ESP8266HTTPClient.h>
#include <BlynkSimpleEsp8266.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";

WidgetTable table;
BLYNK_ATTACH_WIDGET(table, V1);

int rowIndex = 0;

void setup()
{
  // Debug console
  Serial.begin(115200);

  Blynk.config(auth);


  table.addRow(0,"Sole",1);
  table.pickRow(0);
  table.addRow(1,"Luna",1);
  table.addRow(2,"Temperatura Esterna",1);
  table.addRow(3,"Temperatura Interna",1);
}

void loop()
{
  Blynk.run();
}

It’s in the docs…
http://docs.blynk.cc/#blynk-firmware-configuration-blynkconfig

“Note: Just after Blynk.config(…), Blynk is not yet connected to the server.
It will try to connect when it reaches first Blynk.run() or Blynk.connect()call.”

I changed the code but the behaviour doesn’t change. I attched the debug log

WidgetTable table;
BLYNK_ATTACH_WIDGET(table, V1);

int rowIndex = 0;
bool firstrun = true;

void setup()
{
  // Debug console
  Serial.begin(115200);

  Blynk.config(auth);



}

void loop()
{
  Blynk.run();
  if (firstrun) {
    Serial.println("firstrun");
    table.addRow(0, "Sole", 1);
    table.pickRow(0);
    table.addRow(1, "Luna", 1);
    //table.addRow(2,"Temperatura Esterna",1);
    //table.addRow(3,"Temperatura Interna",1);
    firstrun = !firstrun;
  }

}

Perfect ! Now it’s works.
Marked the topi as solved

You may want to refresh your Auth code, as you shared it in the last post. Wouldn’t want people writing naughty entries into your table would we? :open_mouth:
