Dear Sir,
With Blynk2.0
When my Esp32 is not connected to the Wi-Fi router board, my esp32 resets every 30 seconds, which turns the output devices OFF and ON on every reset. Please resolve this issue of wifi connection timeout.
Thanks

My Program code and results are given below for dimmer.

#define BLYNK_PRINT Serial
#include <RBDdimmer.h>
#define outputPin 27 // PWM pin for dimmer
#define zerocross 26 // for boards with CHANGEBLE input pins
dimmerLamp dimmer(outputPin, zerocross); //initialase port for dimmer for ESP8266, ESP32, Arduino due boards
int outVal = 0; // Intialisation value for dimmer
int dim_val; // dimmer value to dim the appliance
#define APP_DEBUG
#include "BlynkEdgent.h"
void setup()
{
Serial.begin(115200);
delay(100);
dimmer.begin(NORMAL_MODE, ON); //dimmer initialisation: name.begin(MODE, STATE)
BlynkEdgent.begin();
}
void loop()
{
BlynkEdgent.run();
}
BLYNK_WRITE(V0) { // Set to your virtual pin
outVal = param.asInt(); // Get State of Virtual Button
dim_val = map(outVal, 0, 100, 0, 100); // mapped the value for dimmer
dimmer.setPower(dim_val); // Set dimmer power
Blynk.virtualWrite(V1, dim_val); //sending to Blynk
}

Anyone reply from blynk community the above issue?
The board reset is a part of our example sketch. In this example, if device cannot connect to the network, it enters an ERROR state, indicates it and resets. Feel free to adjust it to your needs.
