For end school project i have to do  Arduino and LORA net
I have bought 2 sx 1276 and 2 antenna (868 MHZ)
https://www.aliexpress.com/item/1005002925290600.html?spm=a2g0o.productlist.0.0.714c14b2v3XLYQ&algo_pvid=e3ae67dd-fbe6-4394-9bda-db58f51a27f2&algo_exp_id=e3ae67dd-fbe6-4394-9bda-db58f51a27f2-3
https://www.aliexpress.com/item/32850539643.html?spm=a2g0o.store_pc_allProduct.8148356.3.638b21fdYtGxtH.
I have do some test but i can’t have communication (see attach)
Can you help me?

well Actually i didnt understand your code. but i see you are not using usb parameter setting device. I am strongly recommend to use that part for edditing parameter setting for Lora E32.

https://urun.n11.com/arduino-urunleri-ve-setleri/lora-parametre-ayarlari-icin-usb-stick-usb-uart-cp2102-e15-usb-t2-P479061354

anyway lets continue to dangerous way.

primarily, you should make a connection M0 and M1 to 5v and than use that for setting E32 lora. original code is over here:

https://github.com/xreef/LoRa_E32_Series_Library/blob/master/examples/arduinoSetConfiguration/arduinoSetConfiguration.ino

 * M0         ----- 3.3v
 * M1         ----- 3.3v

 * RX         ----- PIN 3 (PullUP & Voltage divider)
 * AUX        ----- Not connected
 * VCC        ----- 3.3v/5v
 * GND        ----- GND

  // Startup all pins and UART
 e32ttl100.begin();
  ResponseStructContainer c;

After you set 2 lora modules with same paremeters and same channel but different adress. one adres should be 44 and another adres should be 63

you can use my sample codes like that:

circuit should be like that and be careful for be wary of contactless situations. for test using you can use without rezistance.

this code will send message to adress 44

#include "LoRa_E32.h"
#include <SoftwareSerial.h>
  SoftwareSerial mySerial(10, 11);
  /*
   Pinler     Arduino Nano    Lora E32 433T20d
                  11                3
                  10                4
*/
  LoRa_E32 e32ttl(&mySerial);
  struct Signal {
  char type[15] = "Fixaj.com";
  byte temp[4];
} data;
    void setup() {
  Serial.begin(9600);
  e32ttl.begin();
  delay(500);
}
  void loop() {
    ResponseStatus rs = e32ttl.sendFixedMessage(0, 44, 23, &data, sizeof(Signal));
  Serial.println(rs.getResponseDescription());
    delay(2000);
    while (e32ttl.available()  > 1) {
    ResponseStructContainer rsc = e32ttl.receiveMessage(sizeof(Signal));
    struct Signal data = *(Signal*) rsc.data;
    Serial.print("Yer: ");
    Serial.println(data.type);
    Serial.print("Ortam Sıcaklığı: ");
    Serial.println(*(float*)(data.temp));
    rsc.close();
  }
}

and this code will receive and than send to adres 63

#include "LoRa_E32.h"
#include <SoftwareSerial.h>
SoftwareSerial mySerial(10, 11); // Arduino RX <-- e32 TX, Arduino TX --> e32 RX
LoRa_E32 e32ttl(&mySerial);
  struct Signal {
  char type[15];
  byte temp[4];
} data;
  void setup() {
  Serial.begin(9600);
  e32ttl.begin();
  delay(500);
}
  void loop() {
  while (e32ttl.available()  > 1) {
      // Gelen mesaj okunuyor
    ResponseStructContainer rsc = e32ttl.receiveMessage(sizeof(Signal));
    struct Signal data = *(Signal*) rsc.data;
    Serial.print("Gelen Messaj: ");
    Serial.println(data.type);
    rsc.close();
      //Gönderilecek paket veri hazırlanıyor
    struct Signal  {
      char type[15] = "Bebek Odası";
      byte temp[4];
    } data2;
      *(float*)(data2.temp) = 19.2;
        ResponseStatus rs = e32ttl.sendFixedMessage(0, 63, 23, &data2, sizeof(Signal));
    Serial.println(rs.getResponseDescription());
    }
  }

original code is over here:
