OMA LWM2M Standalone Example
|
||||||
|
====================================
|
||||||
|
|
||||||
|
This is an example of how to make use of the OMA LWM2M and CoAP
|
||||||
|
implementation from Contiki in a native application.
|
||||||
|
|
||||||
|
The Makefile will copy necessary files from Contiki to the subfolder
|
||||||
|
```oma-lwm2m-src``` and then compile the example ```lwm2m-example```
|
||||||
|
as a native application. By copying only the needed source files,
|
||||||
|
the example can be used outside the Contiki source tree.
|
||||||
|
|
||||||
|
### Running the OMA LWM2M example
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd contiki/examples/oma-lwm2m/standalone
|
||||||
|
make
|
||||||
|
./lwm2m-example
|
||||||
|
```
|
||||||
|
|
||||||
|
The example application will start a CoAP server listening on
|
||||||
|
localhost port 5683 with an example OMA LWM2M device object.
|
||||||
|
|
||||||
|
|
||||||
|
### Testing the OMA LWM2M example
|
||||||
|
|
||||||
|
The Copper (Cu) Firefox addon can be used to access the LWM2M example.
|
||||||
|
|
||||||
|
1. Start the OMA LWM2M example as described above.
|
||||||
|
|
||||||
|
2. 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).
|
||||||
|
|
||||||
|
3. Start Copper and discover resources at coap://127.0.0.1:5683/
|
||||||
|
It should find three objects named 0, 1, and 3.
|
||||||
|
|
||||||
|
4. Browse to the device type resource at coap://127.0.0.1:5683/3/0/17
|
||||||
|
(object 3, instance 0, resource 17) and then click ```GET```.
|
||||||
|
As device type the LWM2M example should return the text "lwm2m-example".
|
||||||
|
|
||||||
|
5. Browse to the time resource at coap://127.0.0.1:5683/3/0/13
|
||||||
|
Every time you click ```GET```, it should return the number of seconds
|
||||||
|
since the example application was started.
|
||||||
|
|
||||||
|
### Moving the example outside Contiki
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd contiki/examples/oma-lwm2m/standalone
|
||||||
|
make copy
|
||||||
|
```
|
||||||
|
|
||||||
|
Copy the example directory contents to a directory outside Contiki.
|
||||||
|
Remove the Makefile ```Makefile.contiki``` and the remaining Makefile
|
||||||
|
will compile the example independent of the Contiki source tree.
|
||||||
|
|
||||||
|
|
||||||
|
The Hex Transport can be tested together with DTLS using:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
make clean
|
||||||
|
make TRANSPORT=hex MAKE_WITH_DTLS=1
|
||||||
|
javac Hex2UDP.java
|
||||||
|
java Hex2UDP leshan.eclipse.org 5684 ./lwm2m-example
|
||||||
|
```
|
||||||
|
|
||||||
|
Note that you need to configure the Leshan server with the correct
|
||||||
|
key and ID.
|
||||||
|
|
||||||
|
(without DTLS it should be 5683 for CoAP)
