Macros
#define	DEBUG   DEBUG_NONE
	FOR HC-06 COMPLIANCE TODO: -Add compression options to UDP, currently only supports both ports compressed or both ports elided. More...
#define	MAC_MAX_PAYLOAD   (127 - 2)
	Maximum available size for frame headers, link layer security-related overhead, as well as 6LoWPAN payload. More...
#define	COMPRESSION_THRESHOLD   0
	Some MAC layers need a minimum payload, which is configurable through the SICSLOWPAN_CONF_MIN_MAC_PAYLOAD option. More...
#define	sicslowpan_buf   uip_buf
	The buffer used for the 6lowpan processing is uip_buf. More...
