Thanks for the comments. Tried out several pins, had a seeed ranger helped out. Managed to create transmit and receiving code, both Lora initialised. One was transmitting, but the receiver did not receive the message. No idea what went wrong, but here are the codes for the transmit.
#include <Arduino.h>
#include <SX126x-Arduino.h>
#include <SPI.h>
// Pin Definitions (based on Seeed Studio Wiki)
const int LORA_RESET_PIN = 12; // RESET
const int LORA_DIO1_PIN = 14; // DIO1
const int LORA_BUSY_PIN = 13; // BUSY
const int LORA_NSS_PIN = 15; // NSS / CS
const int LORA_SCLK_PIN = 6; // SCK
const int LORA_MISO_PIN = 8; // MISO
const int LORA_MOSI_PIN = 7; // MOSI
// LoRa Settings
#define RF_FREQUENCY 868E6 // Asia Frequency
#define TX_OUTPUT_POWER 22 // dBm
// Buffers
#define BUFFER_SIZE 64
static uint8_t TxdBuffer[BUFFER_SIZE];
// LoRa Radio Events
static RadioEvents_t RadioEvents;
hw_config hwConfig;
// Function Declarations
void OnTxDone(void);
void OnTxTimeout(void);
// LoRa Initialization
void setup() {
Serial.begin(115200);
delay(1000);
Serial.println("Initializing LoRa Transmitter...");
// Configure LoRa Hardware
hwConfig.CHIP_TYPE = SX1262_CHIP;
hwConfig.PIN_LORA_RESET = LORA_RESET_PIN;
hwConfig.PIN_LORA_NSS = LORA_NSS_PIN;
hwConfig.PIN_LORA_SCLK = LORA_SCLK_PIN;
hwConfig.PIN_LORA_MISO = LORA_MISO_PIN;
hwConfig.PIN_LORA_MOSI = LORA_MOSI_PIN;

hwConfig.PIN_LORA_BUSY = LORA_BUSY_PIN;
// Initialize LoRa Hardware
lora_hardware_init(hwConfig);
// Setup Radio Event Callbacks
RadioEvents.TxDone = OnTxDone;
RadioEvents.TxTimeout = OnTxTimeout;
// Initialize the Radio
Radio.Init(&RadioEvents);
Radio.SetChannel(RF_FREQUENCY);
// Configure TX Settings
Radio.SetTxConfig(MODEM_LORA, TX_OUTPUT_POWER, 0, 0, 7, 1, 8, false, true, 0, 0, false, 3000);
Serial.println("LoRa Transmitter Initialized.");
}
void loop() {
// Prepare and Send Data
const char* message = "Hello LoRa!";
memset(TxdBuffer, 0, BUFFER_SIZE);
strncpy((char*)TxdBuffer, message, BUFFER_SIZE);
Serial.printf("Sending Message: %s\n", message);
Radio.Send(TxdBuffer, strlen(message));
// Wait before sending the next message
delay(3000); // Adjust this value as needed
}
// Event Callbacks
void OnTxDone(void) {
Serial.println("Transmission Complete.");
}
void OnTxTimeout(void) {
Serial.println("Transmission Timeout.");
}

}

}

}
seems as it works best that way, add some code to verify the pins You asign are the ones it knows , ie. CS in cases of SPI, or SS in Flash or SD card code. better to know for sure than jump without the Net , " Capisce

LOL we won’t care SOLUTIONS is what makes this place a source for us All
