Thanks a lot, I tried your code, but it doesn’t work. Is there a problem here? " timer.setTimeout(30000L, { . . .

Mainly used these codes：
-
- List item
#define BLYNK_PRINT Serial // This prints to Serial Monitor
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
char auth[] = “xxxxxxxxxx”;
char ssid[] = “xxxxxxxxxx”;
char pass[] = “xxxxxxxxxx”;
//char server[] = “xxx.xxx.xxx.xxx”; // IP for Local Cloud Server
char server[] = “blynk-cloud.com”; // URL for Blynk Cloud Server
int port = 8080;
int ReCnctFlag; // Reconnection Flag
int ReCnctCount = 0; // Reconnection counter
BlynkTimer timer;
void setup() {
Serial.begin(115200);
pinMode(2, OUTPUT);
WiFi.begin(ssid, pass); // Non-blocking if no WiFi available
Blynk.config(auth, server, port);
Blynk.connect();
}
BLYNK_CONNECTED() {
Serial.println(“Cconnected”);
ReCnctCount = 0;
}
void loop() {
timer.run();
if (Blynk.connected()) { // If connected run as normal
Blynk.run();
} else if (ReCnctFlag == 0) { // If NOT connected and not already trying to reconnect, set timer to try to reconnect in 30 seconds
ReCnctFlag = 1; // Set reconnection Flag
Serial.println(“Starting reconnection timer in 30 seconds…”);
timer.setTimeout(30000L, { // Lambda Reconnection Timer Function
ReCnctFlag = 0; // Reset reconnection Flag
ReCnctCount++; // Increment reconnection Counter
Serial.print(“Attempting reconnection #”);
Serial.println(ReCnctCount);
Blynk.connect(); // Try to reconnect to the server
}); // END Timer Function
}
