Detailed Description

6LowPAN output for IPv6. Uses ND tables for link-layer addressing. Fragments packets to 6LowPAN units.

Macro Definition Documentation

LOWPAN6_TMR_INTERVAL

#define LOWPAN6_TMR_INTERVAL   1000

1 second period

Function Documentation

lowpan6_output()

err_t lowpan6_output	(	struct netif *	netif,
		struct pbuf *	q,
		const ip6_addr_t *	ip6addr
	)

Resolve and fill-in IEEE 802.15.4 address header for outgoing IPv6 packet.

Perform Header Compression and fragment if necessary.

Parameters

netif	The lwIP network interface which the IP packet will be sent on.
q	The pbuf(s) containing the IP packet to be sent.
ip6addr	The IP address of the packet destination.

Returns

err_t

lowpan6_tmr()

void lowpan6_tmr

(

void

)

Periodic timer for 6LowPAN functions:

• Remove incomplete/old packets

tcpip_6lowpan_input()

err_t tcpip_6lowpan_input	(	struct pbuf *	p,
		struct netif *	inp
	)

Pass a received packet to tcpip_thread for input processing

Parameters

p	the received packet, p->payload pointing to the IEEE 802.15.4 header.
inp	the network interface on which the packet was received
