Is your feature request related to a problem?

Hello,

I am experiencing difficulties connecting my Heltec LoRa ESP32 V2 module to The Things Network (TTN) server using the OTAA example code provided by the TTN_esp32 library. I have encountered errors with both the latest and previous versions of the library and ESP32 board manager.

Setup Details:

Heltec LoRa ESP32 V2
TTN_esp32 library version: 0.1.7
ESP32 board manager version: 3.0.2
Code Used:

#include <TTN_esp32.h>
#include "TTN_CayenneLPP.h"

const char* devEui = "70B3D57ED005EC18";
const char* appEui = "0000000000000100";
const char* appKey = "C7A02794D8631B7A2E307F766C8BC3F6";

TTN_esp32 ttn;
TTN_CayenneLPP lpp;

void message(const uint8_t* payload, size_t size, uint8_t port, int rssi)
{
    Serial.println("-- MESSAGE");
    Serial.printf("Received %d bytes on port %d (RSSI=%ddB) :", size, port, rssi);
    for (int i = 0; i < size; i++)
    {
        Serial.printf(" %02X", payload[i]);
    }
    Serial.println();
}

void setup()
{
    Serial.begin(115200);
    Serial.println("Starting");
    ttn.begin();
    ttn.onMessage(message);
    ttn.join(devEui, appEui, appKey);
    Serial.print("Joining TTN ");
    while (!ttn.isJoined())
    {
        Serial.print(".");
        delay(500);
    }
    Serial.println("\njoined !");
    ttn.showStatus();
}

void loop()
{
    static float nb = 18.2;
    nb += 0.1;
    lpp.reset();
    lpp.addTemperature(1, nb);
    if (ttn.sendBytes(lpp.getBuffer(), lpp.getSize()))
    {
        Serial.printf("Temp: %f TTN_CayenneLPP: %d %x %02X%02X\n", nb, lpp.getBuffer()[0], lpp.getBuffer()[1],
            lpp.getBuffer()[2], lpp.getBuffer()[3]);
    }
    delay(10000);
}

Steps Taken:

1.Verified the correct installation of the latest ESP32 board support package.
2.Tried different versions of the TTN_esp32 library and ESP32 board manager.
3.Ensured the device is powered properly and connected with antenna .
Despite these efforts, the issue persists. I would appreciate any guidance or suggestions on resolving this problem.

Thank you for your assistance.
