Hi rgot-org, first you make grate job with your lib. i have a problem with the heltec wireless stick connection to the ttn:

my code in from ino file:

include

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

const char devEui = "1212121212121212"; //changer avec de devEui TTN const char appEui = "70B3D57ED002BC1A"; // changer avec le appEui TTN const char *appKey = "CBFF7FE560C4F6D3140DC4E943C91522"; // changer avec le appKey TTN // wireless stick pinout

define UNUSED_PIN 0xFF

define SS 18

define RST_LoRa 14

define DIO0 26

define DIO1 35

define DIO2 34

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.begin(SS, UNUSED_PIN, RST_LoRa, DIO0,DIO1,DIO2); 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() { byte data[1]; data[0] = 1; static float nb = 18.2; // nb += 0.1; // lpp.reset(); // lpp.addTemperature(1, nb); // if (ttn.sendBytes(lpp.getBuffer(), lpp.getSize())) Serial.print(data[0]); if (ttn.sendBytes(data, sizeof(data))) { Serial.printf("Data: %f TTN_CayenneLPP: %d %x %02X%02X\n", data);

// 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); }

the serial monitor show only :

checkKeys] provisioned, no session Using stored keys to join 3708: [Event] JOINING Joining TTN ...........316640: [Event] TXSTART ............710441: [Event] JOIN_TXCOMPLETE ............................................................................................................................4593451: [Event] TXSTART .............4987253: [Event] JOIN_TXCOMPLETE ....

I send one byte wir number 1, but no connection to ttn

can you help me?

thanks

Sebastian

The event JOIN_TXCOMPLETE suggests that you are not receiving the Join Accept downlink message. This issue can occur when using a single channel gateway, a TTIG (with not much traffic) or antenna/region config issues. Does any of this apply?

Hi Enwi, the antenna is Standard 868 mz. I Take a Dragon lorahut in raspi this is a 1 Channel hat

Hello sebakiller2018. Lorawan does not work very well with a 1 channel gateway, it is not intended for.
