Cytron Esp8266 wifi shield not responding to Blynk

Postby daniel » Sat Feb 29, 2020 3:20 pm

I purchased a unit of Cytron esp8266 wifi shield and follow this official user manual and it works great all the way to the simple wifi server part. but when I follow the video tutorial all I get is this from serial monitor:

___ __ __
/ _ )/ /_ _____ / /__
/ _ / / // / _ \/ '_/
/____/_/\_, /_//_/_/\_\
/___/ v0.6.1 on Arduino Uno
[598] Connecting to <my wifi>
[1608] ESP not responding

here is my code (I put the RX TX jumper to D2 and D3):

#define BLYNK_PRINT Serial

#include <ESP8266_Lib.h>
#include <BlynkSimpleShieldEsp8266.h>

char auth[] = "<my auth>";

char ssid[] = "<my ssid>";
char pass[] = "<my password>";

#include <SoftwareSerial.h>
SoftwareSerial EspSerial(2, 3);

#define ESP8266_BAUD 115200

ESP8266 wifi(&EspSerial);

void setup()




  Blynk.begin(auth, wifi, ssid, pass);

void loop()

I already tried the AT commands and it is working fine. why it is not working when connecting to Blynk?
