KC868-A2 V2.4 +SIM7600E-L1C

[ktmustafa]

Hello,
I used the KC868-A2 AT debug code to test the connection with the SIM7600E-L1C module. However, I did not get any response... The serial monitor keeps showing " Initializing... " only. Code as below. I would appreciate it if you could help solve this issue.

Thank you

Code:

#include <SoftwareSerial.h>
#include <Arduino.h>

SoftwareSerial gsmSerial(5, 13); ////Rx, Tx for SMS Modem

void setup() {
  Serial.begin(115200);
  gsmSerial.begin(9600);
}

void loop() {
  Serial.println("Initializing...");
  delay(1000);
  gsmSerial.println("AT");
  updateSerial();
  delay(3000);
 
}

void updateSerial()
{
  delay(1000);
  while (Serial.available())
  {
    gsmSerial.write(Serial.read());//Forward what Serial received to Software Serial Port
  }
  while(gsmSerial.available())
  {
    Serial.write(gsmSerial.read());//Forward what Software Serial received to Serial Port
  }
}
