This is the new example for the Erbium REST Engine
==================================================
A Quick Introduction to the Erbium (Er) REST Engine
===================================================
EXAMPLE FILES
-------------
rest-server-example.c: A RESTful server example showing how to use the REST layer to develop server-side applications (at the moment only CoAP is implemented for the REST Engine).
coap-client-example.c: A CoAP client that polls the /toggle resource every 10 seconds and cycles through 4 resources on button press (target address is hard-coded).
er-example-server.c: A RESTful server example showing how to use the REST layer to develop server-side applications (at the moment only CoAP is implemented for the REST Engine).
er-example-client.c: A CoAP client that polls the /actuators/toggle resource every 10 seconds and cycles through 4 resources on button press (target address is hard-coded).
er-plugtest-server.c: The server used for draft compliance testing at ETSI IoT CoAP Plugtest in Paris, France, March 2012 (configured for minimal-net).
PRELIMINARIES
-------------
a) Make sure rpl-border-router has the same stack and fits into mote memory:
Disable RDC in border-router project-conf.h
- Make sure rpl-border-router has the same stack and fits into mote memory:
You can disable RDC in border-router project-conf.h (not really required as BR keeps radio turned on).
#undef NETSTACK_CONF_RDC
#define NETSTACK_CONF_RDC nullrdc_driver
b) For convenience, define the Cooja addresses in /etc/hosts
- For convenience, define the Cooja addresses in /etc/hosts
aaaa::0212:7401:0001:0101 cooja1
aaaa::0212:7402:0002:0202 cooja2
...
c) Get the Copper CoAP browser from https://addons.mozilla.org/en-US/firefox/addon/copper-270430/
d) Optional: Save your target as default target
- Get the Copper (Cu) CoAP user-agent from https://addons.mozilla.org/en-US/firefox/addon/copper-270430/
- Optional: Save your target as default target
$ make TARGET=sky savetarget
COOJA HOWTO
-----------
Server only:
1) $ make TARGET=cooja rest-server-example.csc
1) $ make TARGET=cooja server-only.csc
2) Open new terminal
3) $ make connect-router-cooja
4) Start Copper and discover resources at coap://cooja2:5683/
- Choose "Click button on Sky 2" from the context menu of mote 2 (server) after requesting /test/separate
- Do the same when observing /test/event
With client:
1) $ make TARGET=cooja coap-client-server-example.csc
1) $ make TARGET=cooja server-client.csc
2) Open new terminal
3) $ make connect-router-cooja
4) Wait until red LED toggles on mote 2 (server)

DETAILS
-------
The Erbium CoAP currently implements draft 08 (name "er-coap-07" stems from last technical draft changes).
Central features are commented in rest-server-example.c.
Erbium currently implements draft 08 (name "er-coap-07" stems from last technical draft changes).
Central features are commented in er-example-server.c.
In general, apps/er-coap-07 supports:
* All draft 08 header options
* CON Retransmissions (note COAP_MAX_OPEN_TRANSACTIONS)
* Blockwise Transfers (note REST_MAX_CHUNK_SIZE)
* Separate Responses (see rest_set_pre_handler() and coap_separate_handler())
* Resource discovery
* Blockwise Transfers (note REST_MAX_CHUNK_SIZE, see er-plugtest-server.c for Block1 uploads)
* Separate Responses (no rest_set_pre_handler() required anymore, note coap_separate_accept(), _reject(), and _resume())
* Resource Discovery
* Observing Resources (see EVENT_ and PRERIODIC_RESOURCE, note COAP_MAX_OBSERVERS)
REST IMPLEMENTATIONS
--------------------
The Makefile uses WITH_COAP to configure different implementations for the Erbium REST Engine.
* WITH_COAP=7 uses Erbium CoAP 07 apps/er-coap-07/.
The default port for coap-07 is 5683.
The Makefile uses WITH_COAP to configure different implementations for the Erbium (Er) REST Engine.
* WITH_COAP=7 uses Erbium CoAP 08 apps/er-coap-07/.
The default port for coap-07/-08 is 5683.
* WITH_COAP=3 uses Erbium CoAP 03 apps/er-coap-03/.
The default port for coap-03 is 61616.
er-coap-03 produces some warnings, as it not fully maintained anymore.
