get()

bool get	(	uint8_t *	buff,
		uint32_t	len
	)

Description

This api allows to get the key of P2P mode encryption

Syntax

api.lorawan.enckey.get(buff, len)

Parameters

buff	the buffer to store encryption key
len	the length of encryption key(must be 16 bytes)

Returns

bool

Return values

TRUE	for getting encryption key success
FALSE	for getting encryption key failure

Example

  long startTime;
  char * node_encrypt_key = "aaaabbbbccccdddd";
  uint8_t encrypt_buff[16];

set()

bool set	(	uint8_t *	buff,
		uint32_t	len
	)

Description

This api allows to set the key of P2P mode encryption

Syntax

api.lorawan.enckey.set(buff, len)

Parameters

buff	the buffer to set encryption key
len	the length of encryption key(must be 16 bytes)

Returns

bool

Return values

TRUE	for setting encryption key success
FALSE	for setting encryption failure
