❓ Help SX1278 LoRa Communication

[Phrog]

Baka may marunong sa LoRa dito, using Arduino. Nung una nakakapag communicate pa sila ehh
Tapos nung nag add na ako ng ibang components ayaw na, hindi ko sure kung bakit.
Now I'm testing them without other components, pero ayaw padin.

//TX CODE
#include <SPI.h>
#include <LoRa.h>

void setup() {
  Serial.begin(9600);
  while (!Serial);

  Serial.println("LoRa Receiver Test");

  if (!LoRa.begin(915E6)) {  // Initialize LoRa
    Serial.println("ERROR: LoRa module not detected!");
    while (1);  // Halt execution if LoRa fails
  }

  Serial.println("LoRa module detected successfully!");
  Serial.println("Waiting for packets...");
}

void loop() {
  int packetSize = LoRa.parsePacket();
 
  if (packetSize) {  // If a packet is received
    Serial.print("Received packet: '");

    while (LoRa.available()) {
      Serial.print((char)LoRa.read());  // Read and print received data
    }

    Serial.print("' with RSSI ");
    Serial.println(LoRa.packetRssi());  // Print RSSI (signal strength)
  }
}

//RX CODE
#include <SPI.h>
#include <LoRa.h>

void setup() {
  Serial.begin(9600);
  while (!Serial);

  Serial.println("LoRa Receiver Test");

  if (!LoRa.begin(915E6)) {  // Initialize LoRa
    Serial.println("ERROR: LoRa module not detected!");
    while (1);  // Halt execution if LoRa fails
  }

  Serial.println("LoRa module detected successfully!");
  Serial.println("Waiting for packets...");
}

void loop() {
  int packetSize = LoRa.parsePacket();
 
  if (packetSize) {  // If a packet is received
    Serial.print("Received packet: '");

    while (LoRa.available()) {
      Serial.print((char)LoRa.read());  // Read and print received data
    }

    Serial.print("' with RSSI ");
    Serial.println(LoRa.packetRssi());  // Print RSSI (signal strength)
  }
}

Wiring on Both Uno looks like this without the Potentiometer
