This example features a simple application sending udp packets on port 0xF0B0,
|
||||
from port F0B1, to a udp receiver. It must be used in conjonction with a node
|
||||
running the udp-receiver-ipv6 example.
|
||||
|
||||
We use this example to test UDP, and most particularly UDP header compression
|
||||
with IPv6 and 6lowpan support. When IPv6 is used over an 802.15.4 link,
|
||||
6lowpan acts as an adaptation layer between IPv6 and MAC. In particular,
|
||||
it can compress IP headers and UDP headers.
|
||||
|
||||
With both HC1 and HC01 header compression schemes, UDP 16-bit ports are
|
||||
compressed to 4 bits if they are between F0B0 and F0BF.
|
||||
|
||||
sender behavior:
|
||||
The sender is implemented in examples/udp-sender-ipv6/example-udp-sender.c
|
||||
and acts in the following way:
|
||||
it waits 15 seconds (to be sure the node configures a global address, in case
|
||||
a router on the link sends router advertisements usable for address
|
||||
autoconfiguration) , then sends 5 UDP packets to the receiver address
|
||||
entered hard-wired in the source code.
|
||||
|
||||
receiver behavior:
|
||||
When receiving a packet, the receiver answers with a simmilar packet.
|
||||
|
||||
To run this example, contiki-conf.h must have at least the following flags
|
||||
values:
|
||||
#define UIP_CONF_UDP 1
|
||||
#define UIP_CONF_IPV6 1
|
||||
|
||||
You must configure addresses example-udp-sender.c and
|
||||
examples/udp-receiver-ipv6/example-udp-receiver.c which match your
|
||||
platforms addresses.
