I am using a lora gps sheild with an esp 8266 and blynk please help regurading programming rx node

Using Arduino Project Guidance

#define BLYNK_PRINT Serial
#include <SoftwareSerial.h>
#include <ESP8266_Lib.h>
#include <BlynkSimpleShieldEsp8266.h>
#include <SPI.h>
#include <LoRa.h>
#include <Ethernet.h>
String longi;
String latt;
float a;
float b;

SoftwareSerial EspSerial(4, 3); // RX, TX

char auth[] = "4RYGKOFS-V7ihYHwuGl6F4EjirgzVgI-";
WidgetMap myMap(V0);
BlynkTimer timer;

char ssid[] = "redmi";
char pass[] = "";
unsigned int move_index = 1;
#define ESP8266_BAUD 115200
ESP8266 wifi(&ESPSerial);
void setup() {
Serial.begin(9600);
while (!Serial);
EspSerial.begin(ESP8266_BAUD);
Serial.println("LoRa Receiver");
if (!LoRa.begin(868E6)) {
Serial.println("Starting LoRa failed!");
while (1);
}
Blynk.begin(auth, wifi, ssid, pass);
}

void loop() {
Blynk.run();
myMap.location(move_index, a, b, "GPS_Location");
// try to parse packet
int packetSize = LoRa.parsePacket();
if (packetSize) {
// received a packet
Serial.print("Received packet '");

// read packet
while (LoRa.available()) {
 while (LoRa.available()) {
   longi = LoRa.readStringUntil(':');
   Serial.print(longi);
   a=longi.toFloat();
    Serial.print(" ");
   latt = LoRa.readStringUntil(':');
    Serial.print(latt);
    b=latt.toFloat(); 
}
    // print RSSI of packet

Serial.print("' with RSSI ");
Serial.println(LoRa.packetRssi());

}
timer.run();
}
this ia the code iam using its not working please help

how have you connected the shield to the ESP8266?
what appears on the Serial Monitor?
use code tags around your code - it is very difficult to read as it is
