Preferences.h : data doesn't get stored

Projects Programming

Hi ruilviana,

I tried it that way, with the Startcounter example, which worked perfectly:

#include <Preferences.h>

Preferences preferences;

void setup() {
  Serial.begin(115200);
  Serial.println();

  // Open Preferences with my-app namespace. Each application module, library, etc
  // has to use a namespace name to prevent key name collisions. We will open storage in
  // RW-mode (second parameter has to be false).
  // Note: Namespace name is limited to 15 chars.
  preferences.begin("my-app", false);

  // Remove all preferences under the opened namespace
  //preferences.clear();

  // Or remove the counter key only
  //preferences.remove("counter");

  // Get the counter value, if the key does not exist, return a default value of 0
  // Note: Key name is limited to 15 chars.
  unsigned int counter = preferences.getUInt("counter", 0);

  // Increase counter by 1
  counter++;

  // Print the counter to Serial Monitor
  Serial.printf("Current counter value: %u\n", counter);

  // Store the counter to the Preferences
  preferences.putUInt("counter", counter);

  // Close the Preferences
  preferences.end();

  // Wait 10 seconds
  Serial.println("Restarting in 10 seconds...");
  delay(10000);

  // Restart ESP
  ESP.restart();
}

void loop() {}

But the moment I add data from RemoteXY it doesn't save the data. Hence my cry for help on the forum.
Thanks for the advice!
