Blynk ESP01 Not Responding (sensor reading Arduino Nano and DHT11)

Need Help With My Project

Ok, I manage to get it connected, I think theres a problem on my external power supply, I currently using the nano as power and it works. I need to check it again with my external psu cause i need more power. also I flipped the Rx Tx the Rx pin from Esp connected to Tx nano and Tx esp to Rx nano.

I manage to get it connected with some issue but manage to find a way thanks to this post.

But the connection to my phone sometimes connected and disconnected, is it because of the power?

this is what I get from the terminal. it’s connected to my phone but no data recieved i guess because of the Rx Tx purposely flipped? or the fact that it has unstable connection? I know I can trigger something I’m using D13 from my phone to trigger the nano onboard LED, the led on the esp is blinking everytime I press the button, but the led on the nano is not triggering.

I’m using another code that I mix match but it should be the same

#define BLYNK_PRINT Serial
#include <dht.h>
#include <SimpleTimer.h>
#include <SoftwareSerial.h>
#include <ESP8266_Lib.h>
#include <BlynkSimpleShieldEsp8266.h>

char auth[] = "OqLOk9AHObLAAdyK_05qx7ri4o0zrGIZ";

char ssid[] = "DT_Wifi";
char pass[] = "Sherlock";


SoftwareSerial EspSerial(4, 3); // RX, TX
ESP8266 wifi(&EspSerial);

WidgetTerminal terminal(V1);
SimpleTimer timer;

String vdata = "";

#define dht_apin A0 //Pin DHT_11
dht DHT;

void sendSensor()
{
  DHT.read11(dht_apin);
  long measurement1 = DHT.humidity;
  long measurement2 = DHT.temperature;
  delay(2000);
  Blynk.virtualWrite(V5, measurement1);
  delay(2000);
  Blynk.virtualWrite(V4, measurement2);

  vdata = vdata + "Humidity : " + measurement1 +"%"+", "+ "Temperature : " + measurement2 +" C";
  Blynk.virtualWrite(V2, vdata);
  vdata = "";
}

void setup()
{
  Serial.begin(9600);
  //Set ESP8266 baud rate
  EspSerial.begin(9600);
  Blynk.begin(auth, wifi, ssid, pass,"blynk-cloud.com", 8080);
  
  timer.setInterval(5000L,sendSensor); // 1000L
  terminal.println(F("Blynk v" BLYNK_VERSION ": Device started"));
  terminal.clear();
  terminal.flush();
}

void loop()
{
  timer.run();
  Blynk.run();
}
