Hello, I have connected "Reyax RYLR998" Lora module to ESP32 UART2, but AT commands passed through Hardware serial not working.

Code: Select all

#define RXD2 16
#define TXD2 17

void setup() 
{
  Serial.begin(115200);
  Serial2.begin(115200, SERIAL_8N1, RXD2, TXD2);
  
  Serial.print("\nSetting Lora Module \n");
  
  Serial2.print("AT+IPR=9600\r\n");
  if (Serial2.available()) 
	  Serial.println(Serial2.read());
  delay(1000); 
  
  Serial2.print("AT+BAND=865000000\r\n");
    if (Serial2.available()) 
		Serial.println(Serial2.read());
  delay(1000);

  Serial2.print("AT+ADDRESS=1\r\n");
    if (Serial2.available()) S
	erial.println(Serial2.read());
  delay(1000);
  
  Serial2.print((String)"AT+NETWORKID=5\r\n");
  if (Serial2.available()) 
	  Serial.println(Serial2.read());
  delay(1000); 
}

void loop() 
{ 
  while (Serial2.available()) 
  {
    Serial.print(char(Serial2.read()));
  }
}

I tried

Serial2.print((String)"AT+NETWORKID=5\n");
Serial2.println((String)"AT+NETWORKID=5\r");
Serial2.print((String)"AT+NETWORKID=5\r");
Nothing worked, no response from AT command,
Please help me I have been working on same problem for 2days.
