my code:

#include <TTN_esp32.h>

#include “TTN_CayenneLPP.h”
/***************************************************************************

  • Go to your TTN console register a device then the copy fields
  • and replace the CHANGE_ME strings below
    *************************************************************************/
    const char
    devEui = “CHANGE_ME”; // Change to TTN Device EUI
    const char
    appEui = “CHANGE_ME”; // Change to TTN Application EUI
    const char
    appKey = “CHANGE_ME”; // Chaneg to TTN Application Key

TTN_esp32 ttn ;
TTN_CayenneLPP lpp;

void message(const uint8_t* payload, size_t size, int rssi)
{
Serial.println("-- MESSAGE");
Serial.print(“Received " + String(size) + " bytes RSSI=” + String(rssi) + “db”);
for (int i = 0; i < size; i++)
{
Serial.print(" " + String(payload[i]));
// Serial.write(payload[i]);
}

Serial.println();

}

void setup()
{
Serial.begin(115200);
Serial.println(“Starting”);
ttn.begin();
ttn.onMessage(message); // Declare callback function for handling downlink
// messages from server
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);
}

On the right top corner below Cayenne LPP the network is Acklio. Remove the device and re-add it by first selecting the TTN network and then search for cayenne LPP device.

thanks a lot for help let me.

this solved the issue

have nice day to you
