Exception on Wifi disconnection (Wemos D1) [SOLVED]

I have this simple sketch on Wemos D1 (ESP8266):

#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
char auth[] = "myAuthToken";
char ssid[] = "myNetworkName";
char pass[] = "myPassword";

void setup()
  Blynk.begin(auth, ssid, pass);

void loop()

Everything works perfectly, but when I disconnect my wifi router I have an exception on Wemos:

load 0x4010f000, len 1384, room 16

Now, the big problem is that in this situation my ESP8266 restart and so the relays and other settings will be reset. I know that I can store the relays status using EEPROM, but I need that the esp8266 doesn’t have this exception.

Do you have some suggestion?


This is NOT a Blynk issue… Google the error, and use EspExceptionDecoder.

I fixed the problem.

Just change IwIP Variant to: v1.4 Prebuid
