Function Documentation

uint8_t frame802154_create	(	frame802154_t *	p,
		uint8_t *	buf,
		uint8_t	buf_len
	)

Creates a frame for transmission over the air.

This function is meant to be called by a higher level function, that interfaces to a MAC.

Parameters:

p	Pointer to frame802154_t struct, which specifies the frame to send.
buf	Pointer to the buffer to use for the frame.
buf_len	The length of the buffer to use for the frame.
