bool	get (uint8_t *buf, uint32_t len)

Detailed Description

Description

This api allows the user to access the network identifier(NetID)

Member Function Documentation

get()

bool get	(	uint8_t *	buf,
		uint32_t	len
	)

Description

This api allows the user to get the network identifier(NetID)

Syntax

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

Note

Even though the length of network identifier(NetID) is 3 bytes, you should give 4-bytes buffer for natural alignment

Parameters

buf	the buffer to get network identifier(NetID)
len	the length of network identifier(NetID)(must be 3 bytes)

Returns

bool

Return values

TRUE	for getting network identifier(NetID) successfully
FALSE	for getting network identifier(NetID) failure
