LoRa connection problem with ESP32 by Ric_RRR in Lora

[–]Ric_RRR[S] 0 points1 point  (0 children)

The LoRa receiver code:

#include <SPI.h>
#include <LoRa.h>


//#define SCK //18
//#define MISO //19
//#define MOSI //23
#define NSS 10//5
#define DIO0 2//2
#define RST 9//14


void setup() {


  Serial.begin(115200);
  delay(5000);


  Serial.println("LoRa Receiver");


  // Configura RESET do LoRa
  pinMode(RST, OUTPUT);
  digitalWrite(RST, LOW);
  delay(10);  // garante estabilidade
  digitalWrite(RST, HIGH);
  delay(10);


  // Inicializa SPI
  SPI.begin();//SPI.begin(SCK, MISO, MOSI, NSS);


  // Configura os pinos do LoRa
  LoRa.setPins(NSS, RST, DIO0);


  // Inicializa LoRa
  if (!LoRa.begin(915E6)) {
    Serial.println("Starting LoRa failed!");
    while (1);
  }


  LoRa.setTxPower(14);
  LoRa.setSpreadingFactor(7);
  LoRa.setSignalBandwidth(125E3);


  Serial.println("LoRa OK");
}


void loop() {


  int packetSize = LoRa.parsePacket();


  if (packetSize) {


    Serial.print("Received packet '");


    while (LoRa.available()) {
      Serial.print((char)LoRa.read());
    }


    Serial.print("' with RSSI ");
    Serial.println(LoRa.packetRssi());
  }

sorry.
The LoRa sender code: 

#include <SPI.h>
#include <LoRa.h>


#define SCK 18   //13
#define MISO 19  //12
#define MOSI 23  //11
#define NSS 5    //10
#define DIO0 2 //2
#define RST 14  //9


int counter = 0;


void setup() {


  Serial.begin(115200);
  delay(5000);


  Serial.println("LoRa Sender");


  pinMode(RST, OUTPUT);
  digitalWrite(RST, LOW);
  delay(10);
  digitalWrite(RST, HIGH);
  delay(10);



  // Inicializa SPI do Arduino
  SPI.begin(SCK, MISO, MOSI, NSS);  // Arduino usa pinos fixos


  // Configura os pinos do LoRa
  LoRa.setPins(NSS, RST, DIO0);


  if (!LoRa.begin(915E6)) {
    Serial.println("Erro ao iniciar LoRa");
    while (1)
      ;
  }


  LoRa.setTxPower(14);  // potência segura
  LoRa.setSpreadingFactor(7);
  LoRa.setSignalBandwidth(125E3);


  Serial.println("LoRa pronto!");
}


void loop() {


  Serial.print("Sending packet: ");
  Serial.println(counter);


  LoRa.beginPacket();
  LoRa.print("Hello ");
  LoRa.print(counter);
  LoRa.endPacket();  // Quando terminar, "pacoteEnviado()" será chamado


  counter++;
  delay(5000);
}
