A Quick Introduction to the Erbium (Er) REST Engine
===================================================
Compile the Example
-------------------
./run.sh
OSD-Merkur Board
----------------------
write the images to the OSD-Merkur Board:
./flash.sh
EXAMPLE FILES
-------------
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
-------------
- 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
- For convenience, define the Cooja addresses in /etc/hosts
aaaa::0212:7401:0001:0101 cooja1
aaaa::0212:7402:0002:0202 cooja2
...
- 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 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 server-client.csc
2) Open new terminal
3) $ make connect-router-cooja
4) Wait until red LED toggles on mote 2 (server)
5) Choose "Click button on Sky 3" from the context menu of mote 3 (client) and watch serial output
DETAILS
-------
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, 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 (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.
* WITH_COAP=0 is a stub to link an Erbium HTTP engine that uses the same resource abstraction (REST.x() functions and RESOURCE macros.
TODOs
-----
* Observe client
* Multiple If-Match ETags
* (Message deduplication)

A Quick Introduction to the Erbium (Er) REST Engine
===================================================
EXAMPLE FILES
-------------
- 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 Plugtests. Erbium (Er) participated in Paris, France, March 2012 and
Sophia-Antipolis, France, November 2012 (configured for minimal-net).
PRELIMINARIES
-------------
- 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
- Alternatively, you can use the native-border-router together with the slip-radio.
- For convenience, define the Cooja addresses in /etc/hosts
aaaa::0212:7401:0001:0101 cooja1
aaaa::0212:7402:0002:0202 cooja2
...
- Get the Copper (Cu) CoAP user-agent from
[https://addons.mozilla.org/en-US/firefox/addon/copper-270430](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:
make TARGET=cooja server-only.csc
Open new terminal
make connect-router-cooja
- 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:
make TARGET=cooja server-client.csc
Open new terminal
make connect-router-cooja
- Wait until red LED toggles on mote 2 (server)
- Choose "Click button on Sky 3" from the context menu of mote 3 (client) and
watch serial output
TMOTES HOWTO
------------
###Server:
1. Connect two Tmote Skys (check with $ make TARGET=sky sky-motelist)
make TARGET=sky er-example-server.upload MOTE=2
make TARGET=sky login MOTE=2
2. Press reset button, get address, abort with Ctrl+C:
Line: "Tentative link-local IPv6 address fe80:0000:0000:0000:____:____:____:____"
cd ../ipv6/rpl-border-router/
make TARGET=sky border-router.upload MOTE=1
make connect-router
For a BR tty other than USB0:
make connect-router-port PORT=X
3. Start Copper and discover resources at:
coap://[aaaa::____:____:____:____]:5683/
### Add a client:
1. Change the hard-coded server address in er-example-client.c to aaaa::____:____:____:____
2. Connect a third Tmote Sky
make TARGET=sky er-example-client.upload MOTE=3
MINIMAL-NET HOWTO
-----------------
With the target minimal-net you can test your CoAP applications without
constraints, i.e., with large buffers, debug output, memory protection, etc.
The er-plugtest-server is thought for the minimal-net platform, as it requires
an 1280-byte IP buffer and 1024-byte blocks.
make TARGET=minimal-net er-plugtest-server
sudo ./er-plugtest-server.minimal-net
Open new terminal
make connect-minimal
- Start Copper and discover resources at coap://[fdfd::ff:fe00:10]:5683/
- You can enable the ETSI Plugtest menu in Copper's preferences
Under Windows/Cygwin, WPCAP might need a patch in
<cygwin>\usr\include\w32api\in6addr.h:
21,23c21
< #ifdef __INSIDE_CYGWIN__
< uint32_t __s6_addr32[4];
< #endif
---
> u_int __s6_addr32[4];

< #endif
DETAILS
-------
Erbium implements the Proposed Standard of CoAP. Central features are commented
in er-example-server.c. In general, apps/er-coap supports:
- All draft-18 header options
- CON Retransmissions (note COAP_MAX_OPEN_TRANSACTIONS)
- 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)
TODOs
-----
- Dedicated Observe buffers
- Optimize message struct variable access (directly access struct without copying)
- Observe client
- Multiple If-Match ETags
- (Message deduplication)
