Seeeduino RAK7249 LoRaWAN - AU915

End Devices (Nodes)
1

I’m trying to integrate Seeeduino LoRaWAN to TTN through using my own RAK7249 gateway which is registered and active on the TTN network successfully.

The gateway is programmed for AU915 second-band settings. Namely it’s using uplink channels 8-15 and 65 (916.8-918.2 MHz and 917.5 MHz).

I can see that the Join request is sent to the TTN and a response on 923.3 MHz (The downlink frequency) arrives but it is never acknowledged by the Seeeduino. See below:

The arduino code:
#include <LoRaWan.h>

unsigned char data[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 0xA,};
char buffer[256];

void setup(void)
{
  Serial.begin(115200);
  delay(5000);

  lora.init();

  memset(buffer, 0, 256);
  lora.getVersion(buffer, 256, 1);
  Serial.print(buffer);

  memset(buffer, 0, 256);
  lora.getId(buffer, 256, 1);
  Serial.print(buffer);

  // void setId(char *DevAddr, char *DevEUI, char *AppEUI);
  lora.setId(NULL, "00D433CC276F57D7", "70B3D57ED0024CCA");
  // setKey(char *NwkSKey, char *AppSKey, char *AppKey);
  lora.setKey(NULL, NULL, "32B31BDCB5CBFC4B04500D1BEA4F2F3E");

  lora.setDeciveMode(LWOTAA);
  lora.setDataRate(DR2, AU915);

  lora.setChannel(8, 916.8, DR0, DR5);

  lora.setChannel(14, 918.0, DR0, DR5);
  lora.setChannel(15, 918.2, DR0, DR5);

  lora.setReceiceWindowFirst(0, 923.3);
  lora.setReceiceWindowFirst(1, 923.9);
  lora.setReceiceWindowFirst(2, 924.5);
  lora.setReceiceWindowFirst(3, 925.1);

  lora.setReceiceWindowFirst(6, 926.9);
  lora.setReceiceWindowFirst(7, 927.5);

  lora.setReceiceWindowSecond(923.3, DR8);

  lora.setDutyCycle(false);
  lora.setJoinDutyCycle(false);

  lora.setPower(14);

  while (!lora.setOTAAJoin(JOIN));
}

void loop(void)
{
  bool result = false;

  result = lora.transferPacket("{test: '1234', test2: '234'}", 10);
  //result = lora.transferPacket(data, 10, 10);

  if (result)
  {
    short length;
    short rssi;

    memset(buffer, 0, 256);
    length = lora.receivePacket(buffer, 256, &rssi);

    if (length)
    {
      Serial.print("Length is: ");
      Serial.println(length);
      Serial.print("RSSI is: ");
      Serial.println(rssi);
      Serial.print("Data is: ");
      for (unsigned char i = 0; i < length; i ++)
      {
        Serial.print("0x");
        Serial.print(buffer[i], HEX);
        Serial.print(" ");
      }
      Serial.println();
    }
  }
}

Any help in this matter will be very much appreciated. Thank you!
