BC660K-GL-TE-B with Arduino Mega2560

Hi, I have a problem with communication between my arduino Mega2560 and BC660K-GL-TE-B module which I have connected to arduino with arduino interface on bc660K-gl-te-b. Here is my code:

void setup() {

  Serial.begin(115200);
  Serial.print("AT+IPR=115200\r\n");
  delay(5000);
  if (Serial.available()) {
    String responsex = Serial.readString();
    Serial.println("Response AT+IPR=115200\r\n: " + responsex);
  }

  Serial.print("AT+IPR=?\r\n");
  delay(5000);

  // Read Response
  if (Serial.available()) {
    String response = Serial.readString();
    Serial.println("Response AT+IPR=115200\r\n: " + response);
  }  

  // Turn off sleepmode
  Serial.print("AT+QSCLK=0\r\n");
  delay(5000);  

  // Read Response
  if (Serial.available()) {
    String response1 = Serial.readString();
    Serial.println(" Response AT+QSCLK=0: " + response1);
  }

  Serial.print("AT+QIOPEN=0,0,\"UDP\",\"192.168.0.0\",4242,5000\r\n");
  delay(5000);  

  // Read Response
  if (Serial.available()) {
    String response2 = Serial.readString();
    Serial.println("Response AT+QIOPEN: " + response2);
  }

  Serial.print("AT+QISEND=0,5,\"12345\"\r\n");
  delay(5000);

  // Read Response
  if (Serial.available()) {
    String response3 = Serial.readString();
    Serial.println("Responsee AT+QISEND: " + response3);
  }
}

void loop() {
  
}

And here is a response that I’m getting:


I have no idea what to do. I have tried to set a different baud rate and that also didn’t work…

Can you use the USB-to-UART debugging tool to debug first?
