WiFiNINA

the Nano RP2040 Connectis not mentioned explicitly.

Is there a current document on the "U-blox® Nina W102 +" implementation. With all functions such as WiFiStorage.open () etc.

2

the RP2040 on Nano has 6 MB of flash memory.
the alternative core directly supports FS.

Thanks....I'm on testing both Impementations.
a) the original Arduino
and
b) Earle F. Philhower's

both are using WiFiNINA Lib.

My Question was about the non-dokumentet implemantation of the FS on the ESP32.
There is a WiFiNINA-Exemple "WifiStorage" that use those functions.
Is there any official docu, or have we to analyse the
Arduino NINA-W102 firmware

The CmdHandler

I used it to implement the EEPROM-Replacement...

It works fine!

As we know that, since years, about the FS on ESP's

  #define CONFIG_LEN    120
  
  union conf 
  {
    char buf[CONFIG_LEN];
    
    struct {
      uint8_t valid;                       // 0=no configuration, 1=valid configuration
      char ee_SSID[20];                    // SSID of WiFi
      char ee_password[20];                // Password of WiFi
      uint8_t ee_ip[4];             // fixe ip adr der Station und damit des Websocket-Servers
      uint8_t ee_gatewayByte4;      // 4ter teil der Gateway adr. Die ersten drei sind wie bei der ee_ip
      char ende[10];                // test
    };
  };
  
  conf cfg;

bool ini_eeprom(void){
//---------------------

  uint8_t config_ok =0;
  if (WiFi.status() == WL_NO_SHIELD) {
    HsPrintln("WiFi shield not present");
    return false;
  }

  WiFiStorageFile cfg_file = WiFiStorage.open("/fs/config");

  if (cfg_file) {
    cfg_file.seek(0);
    int ret = cfg_file.read(cfg.buf, CONFIG_LEN);
    cfg_file.close();
    
    // damit ist die struct cfg.xxx   geladen !!!
    
    // offenhs temp einlesen, prüfen und erst dann setzen
    if (ret < CONFIG_LEN || cfg.valid != 1){
      //HsPrintln("Config ev. nicht umfassend!");
    }else{
       config_ok = 1;
    }
  }else{

  }
  if (!config_ok) HsPrintln("Config ev. nicht umfassend!");
  
  check_config();  // prüfen und sicherheits halber min max setzen.
  
  return true;
}
bool saveConfig(void) {
//-------------------------------
  WiFiStorageFile cfg_file = WiFiStorage.open("/fs/config");
  if (! cfg_file) return false;
  cfg_file.erase();
  cfg_file.seek(0);
  cfg_file.write(cfg.buf, CONFIG_LEN);
  cfg_file.close();
  return true;
}
