Function Documentation

lowpan6_input()

err_t lowpan6_input	(	struct pbuf *	p,
		struct netif *	netif
	)

NETIF input function: don't free the input pbuf when returning != ERR_OK!

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_set_context()

err_t lowpan6_set_context	(	u8_t	idx,
		const ip6_addr_t *	context
	)

Set context

lowpan6_set_pan_id()

err_t lowpan6_set_pan_id

(

u16_t

pan_id

)

Set PAN ID

lowpan6_set_short_addr()

err_t lowpan6_set_short_addr	(	u8_t	addr_high,
		u8_t	addr_low
	)

Set short address

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
