Ebyte LORA E32 comunicazione tra Arduino ed esp32

[MASSIMILIANO]

Ciao a tutti sto realizzando un master ed uno slave con LORA E32 dove il tx monta arduino e l RX un ESP32.

Avete uno sketch che posso utilizzare in modo semplice.

Ciao Massimiliano,

qui lo sketch per il sender Arduino

#include "Arduino.h"
//#define E32_TTL_1W
//#define FREQUENCY_915
#include "LoRa_e32.h"

#define RX 4
#define TX 5
#define M0 7
#define M1 6

//HardwareSerial lora(2);
//LoRa_E32 e32ttl1w(&lora,RX,TX, UART_BPS_RATE_9600,SERIAL_8N1);

//LoRa_E32 e32ttl1w(RX, TX, 3); //, 3, 7, 6);
LoRa_E32 e32ttl1w(4, 5, 3, 7, 6);

// Variables globales
unsigned long interval = 15000;          // interval between sends
unsigned long lastSendTime = 0;        // last send time
byte msgCount = 0;            // count of outgoing messages
long randNumber;
void setup() {
  //Inicio comunicacion serie con monitor
  Serial.begin(9600);
  delay(500);

  Serial.println();

  e32ttl1w.begin();

  //Configuro el nodo LoRa
  nodeConfig();
}

void loop() {
  // Wait a few seconds between measurements.

  if (millis() - lastSendTime > interval) {
    // print a random number from 10 to 19
    randNumber = random(10, 20);
    String trama = String(randNumber);
    ResponseStatus rs = e32ttl1w.sendFixedMessage(0, 3, 0x10,trama);
    Serial.println("Sending " + trama);
    Serial.println(rs.getResponseDescription());
    lastSendTime = millis();            // timestamp the message
    msgCount++;
  }
  delay(100);
}

void nodeConfig(){

  ResponseStructContainer c;
  c = e32ttl1w.getConfiguration();
  Configuration configuration = *(Configuration*) c.data;

  configuration.ADDH        = 0x0;
  configuration.ADDL        = 0x1;
  configuration.CHAN        = 0x10;

  configuration.SPED.airDataRate           = AIR_DATA_RATE_010_24;
  configuration.SPED.uartBaudRate          = UART_BPS_9600;
  configuration.SPED.uartParity            = MODE_00_8N1;
  configuration.OPTION.fec                 = FEC_1_ON;
  configuration.OPTION.fixedTransmission   = FT_FIXED_TRANSMISSION;
  configuration.OPTION.ioDriveMode         = IO_D_MODE_PUSH_PULLS_PULL_UPS;
  configuration.OPTION.transmissionPower   = POWER_20;
  configuration.OPTION.wirelessWakeupTime  = WAKE_UP_1250;
  //printParameters(configuration);

// Set configuration changed and set to not hold the configuration
  ResponseStatus rs = e32ttl1w.setConfiguration(configuration, WRITE_CFG_PWR_DWN_SAVE);
  Serial.print("Config: ");
  Serial.println(rs.getResponseDescription());
}

And here the esp32 receiver

#include "Arduino.h"
//#define E32_TTL_1W
//#define FREQUENCY_915
#include "LoRa_E32.h"

// Not needed Serial2 have already this pins
//#define RX 16
//#define TX 17

#define AUX 18
#define M0 21
#define M1 19

//HardwareSerial serial1(2);

//LoRa_E32 e32ttl1w(&serial1,RX,TX, 18, UART_BPS_RATE_9600,SERIAL_8N1);
LoRa_E32 e32ttl1w(&Serial2, AUX, M0, M1);


void setup() {

//  pinMode(M0, OUTPUT);
//  pinMode(M1, OUTPUT);


  //Inicio comunicacion serie con monitor
  Serial.begin(9600);
  delay(500);

  // Establezco M0 y M1 en alto para configurar LoRa
//  digitalWrite(M0, HIGH);
//  digitalWrite(M1, HIGH);

// Startup all pins and UART
	e32ttl1w.begin();
  //Configuro el nodo LoRa
  nodeConfig();

  // Establezco M0 y M1 en bajo para trabajar con LoRa
//  digitalWrite(M0, LOW);
//  digitalWrite(M1, LOW);
}

void loop() {

  if (e32ttl1w.available() > 0) {
    Serial.println("----------");
    ResponseContainer rc = e32ttl1w.receiveMessage();
    Serial.println(rc.data);
    // Is something goes wrong print error
    if (rc.status.code != 1) {
      rc.status.getResponseDescription();
    } else {
    // Print the data received
      Serial.println(rc.data);
    }
  }
  delay(500);
}

void nodeConfig(){

  ResponseStructContainer c;
  c = e32ttl1w.getConfiguration();
  Configuration configuration = *(Configuration*) c.data;

    configuration.ADDH        = 0x0;
    configuration.ADDL        = 0x3;
    configuration.CHAN        = 0x10;

    configuration.SPED.airDataRate           = AIR_DATA_RATE_010_24;
    configuration.SPED.uartBaudRate          = UART_BPS_9600;
    configuration.SPED.uartParity            = MODE_00_8N1;
    configuration.OPTION.fec                 = FEC_1_ON;
    configuration.OPTION.fixedTransmission   = FT_FIXED_TRANSMISSION;
    configuration.OPTION.ioDriveMode         = IO_D_MODE_PUSH_PULLS_PULL_UPS;
    configuration.OPTION.transmissionPower   = POWER_20;
    configuration.OPTION.wirelessWakeupTime  = WAKE_UP_1250;

  //printParameters(configuration);

// Set configuration changed and set to not hold the configuration
  ResponseStatus rs = e32ttl1w.setConfiguration(configuration, WRITE_CFG_PWR_DWN_LOSE);

  Serial.print("Config: ");
  Serial.println(rs.getResponseDescription());

}

 

Per lo shema di connessione di arduino fai riferimento all’articolo dello shield

Ebyte LoRa E32 per Arduino, esp32 o esp8266 : WOR (wake on radio) del microcontrollore e uno shield per Arduino – Part 6

 

 

Credo che sia tutto ok ma magari dammi un feedback.

Ciao Renzo
