This code only works 72 times with arduino

`#include "LoRa_E22.h"
#include <SoftwareSerial.h>

SoftwareSerial mySerial(10, 11);

/*
   Pinler     Arduino Nano    Lora E32 433T20d
                  11                3
                  10                4
*/

LoRa_E22 E22(&mySerial);

struct Signal {
  char type[4] = "Urfa";
  byte role[4];
} data;

#define M0 7
#define M1 6
#define BTN 2
#define LED 9

byte i = 0;

void setup() {
  pinMode(M0, OUTPUT);
  pinMode(M1, OUTPUT);
  digitalWrite(M0, LOW);
  digitalWrite(M1, LOW);

  Serial.begin(9600);
  E22.begin();

}

void loop() {

  struct Signal {
    char type[4] = "Urfa";
    byte role[4];
  } data;

  i = i + 1;

  *(int*)( data.role) = i;

  ResponseStatus rs = E22.sendFixedMessage(0, 1, 25, &data, sizeof(Signal));
//  Serial.println(rs.getResponseDescription());
  Serial.print ("data: "); Serial.println(i);

  delay(1000);
}`

this works until i = 72 after that struct is loosing itselfs

Output:

ı think library need modifications. I have added free() command and fixed. at line 891/892 https://github.com/xreef/EByte_LoRa_E22_Series_Library/blob/master/LoRa_E22.cpp#L894

        memcpy(fixedStransmission->message,(unsigned char*)message,size);
    ResponseStatus status;
    status.code = this->sendStruct((uint8_t *)fixedStransmission, size+3);
    free(fixedStransmission); // Burayı ekledim, I have added this line
    if (status.code!=SUCCESS) return status;
        //free(fixedStransmission);

and at the receiver side I have to add .close() command in example. I didnt see close command in examples like E32 examples

  if (e22ttl.available() > 1) {
    ResponseStructContainer rsc = e22ttl.receiveMessageRSSI(sizeof(Message));

    Serial.println(rsc.status.getResponseDescription());
    struct Message message = *(Message*) rsc.data;
    Serial.println(message.type);
    Serial.println(message.message);
    Serial.println(*(int*)(message.temperature));
    Serial.print("RSSI: "); Serial.println(rsc.rssi, DEC);

    rsc.close(); // Bu satırıda gelen mesajları okuduktan sonra eklemek gerekiyor yoksa arduino donuyor. This line added

  }

it works fine almost 2 days

Thanks, I start check all the examples for the e220 version. Bye Renzo

Your welcome, I have told at this video how to use your library in YouTube? https://youtu.be/LqlZJ986tJI Thanks to much Mehmet.

Hi, It's beautiful. I'll try to share it. Thanks Renzo
