Try Arduino IDE 1.8.8.

Hi Costaa ,
Thanks for quick response
I tried with 1.8.8 too no luck
did you work with wemos D1 Mini
Please advise

We need more details then.

Sketch and Serial Monitor.

99% of my work is with this hardware.

I tried to Upload the sketch , It is not allowing , i am new to blynk community , amazing app
#define BLYNK_PRINT Serial

#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>

char auth[] = “xxxx”;
char ssid[] = “MUNEER 9749”;
char pass[] = “xxxxxxxx”;

void setup()
{
// Debug console
Serial.begin(9600);
Blynk.begin(auth, ssid, pass);
}
void loop()
{
Blynk.run();
}

HI costas this is my full sketch

Reproduced without your token:

#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>

char auth[] = “xxxx”;
char ssid[] = “MUNEER 9749”;
char pass[] = “xxxxxxxx”;

void setup()
{
  Serial.begin(9600); // Debug console
  Blynk.begin(auth, ssid, pass);
}
void loop()
{
  Blynk.run();
}

What do you see in Serial Monitor?

it filed while compiling

It’s your inverted commas that are a problem.
Try this one:

#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>

char auth[] = "xxx";
char ssid[] = "MUNEER 9749";
char pass[] = "xxxxxxxx";

void setup()
{
  Serial.begin(9600); // Debug console
  Blynk.begin(auth, ssid, pass);
}
void loop()
{
  Blynk.run();
}
14

it i done , Now serial screen shows … dots

15

Have you entered your Blynk token and WiFi credentials?

16

wifi credentials yes
not token

17

I just remove token for your security but you need to include it.

18

I added now

19

Connected now?

HI Costas It worked m after reinstalling the IDE 1.8.8 and updated the Esp8266 libraries
Thank you dear , can you tell me which version wemos is better for professional use
