get()

bool get	(	uint8_t *	buf,
		uint32_t	len
	)

Description

This api allows the user to get the application key

Syntax

api.lorawan.appkey.get(buf, len)

Parameters

buf	the buffer to get AppKey
len	the length of AppKey(must be 16 bytes)

Returns

bool

Return values

TRUE	for getting AppKey successfully
FALSE	for getting Appkey failure

Example

  // OTAA Application Key MSB
  uint8_t node_app_key[16] = {0x2B, 0x7E, 0x15, 0x16, 0x28, 0xAE, 0xD2, 0xA6, 0xAB, 0xF7, 0x15, 0x88, 0x09, 0xCF, 0x4F, 0x3E};

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

      api.lorawan.njm.set(RAK_LORA_OTAA); // Set LoRaWan join mode to OTAA

      if(api.lorawan.appkey.set(node_app_key, 16) == true)
          Serial.println("LoRaWan AppKey set success");
      else
          Serial.println("LoRaWan AppKey set fail");
  }

  void loop()
  {
      uint8_t buff[16];

      if(api.lorawan.appkey.get(buff, 16) == true) {
          Serial.print("LoRaWan AppKey = 0x");
          for(int i = 0; i < 16; i++) {
              Serial.printf("%02X", buff[i]);
          }
          Serial.println("");
      } else {
          Serial.println("LoRaWan AppKey get fail");
      }

      delay(1000);
  }

set()

bool set	(	uint8_t *	buf,
		uint32_t	len
	)

Description

This api allows the user to set the application key

Syntax

api.lorawan.appkey.set(buf, len);

Parameters

buf	the buffer to set AppKey
len	the length of AppKey(must be 16 bytes)

Returns

bool

Return values

TRUE	for setting AppKey successfully
FALSE	for setting Appkey failure
