Ciao Massimiliano,
qui lo sketch per il sender Arduino

LoRa_E32 e32ttl1w(4, 5, 3, 7, 6);
// Variables globales
unsigned long interval = 15000; // interval between sends

void setup() {
//Inicio comunicacion serie con monitor
Serial.begin(9600);

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(rs.getResponseDescription());

}
And here the esp32 receiver

void setup() {
// pinMode(M0, OUTPUT);
// pinMode(M1, OUTPUT);
//Inicio comunicacion serie con monitor

delay(500);
// Establezco M0 y M1 en alto para configurar LoRa
// digitalWrite(M0, HIGH);

//Configuro el nodo LoRa
nodeConfig();
// Establezco M0 y M1 en bajo para trabajar con LoRa

}
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(){

Per lo shema di connessione di arduino fai riferimento all’articolo dello shield
Credo che sia tutto ok ma magari dammi un feedback.
