Request Packet to LL-RLP-20 LoRa RF module

Im stuck trying to send a request packet to an LL-RLP-20 wireless module. I have attached the sketch and the relevant parts of the datasheet for the module. I’m just trying to do a simple request so I can see that it’s working properly but am getting no response. Is this how I should do a request packet?
Thanks in advance!

#include <SoftwareSerial.h>

SoftwareSerial lora = SoftwareSerial(10, 11);
uint8_t cycle = 0;
boolean startup = true;

void setup()  
{
  Serial.begin(115200);
  
  Serial.println("Hello from MEGA328");

  pinMode(10, INPUT);
  pinMode(11, OUTPUT);
  lora.begin(115200);

  if (lora)
    Serial.println("LoRa Connected");
}

void loop() // run over and over
{
    
  if (lora.available())
    Serial.write(lora.read());
  if (Serial.available())
    lora.write(Serial.read());

  if (startup) {
    Serial.print("Requesting hardware version. Request #");
    Serial.println(cycle);
    lora.write((byte)0xFF); //Wakeup Preamble 0 (always 0xFF)
    lora.write((byte)0xFF); //Wakeup Preamble 2 (always 0xFF)
    lora.write((byte)0xFF); //Wakeup Preamble 3 (always 0xFF)
    lora.write((byte)0xFF); //Wakeup Preamble 4 (always 0xFF)
    lora.write((byte)0xC4); //Start of Frame (always 0xC4)
    lora.write((byte)0x01); //Command Byte
    lora.write(cycle);      //Message Number (8 bit number, rollover at 255)
    lora.write((byte)0x00); //Payload Length MSB
    lora.write((byte)0x00); //Payload Length LSB
    lora.write((byte)0x06); //Checksum Byte MSB
    lora.write((byte)0x07); //Checksum Byte LSB
    lora.write('\n');       //New line
    cycle++;
    
    startup = false;
  }
  
}

Using SoftwareSerial at 115200 may be pushing it.

What are you talking to, and how is it connected to the Arduino?

I’m happy to use the hardware serial but want a way to interact on my computer’s serial monitor while developing.
I’ using a Pro Mini with a Link Labs LL-RLP-20 module. Datasheet attached.
I connected…
Arduino → Module:
10 → 23(HOST_RXIN)
11 → 24(HOST_TXOUT)
GND → 1(GND)
VCC → 3(VBAT)

Here’s the user guide as well for the serial interface.
