microcoap server test
=====================
This application is meant to get you started with implementing a CoAP server
on RIOT. It uses the GNRC network stack through RIOT's conn socket API.
Usage
=====
To try out the server on native, compile it with
```
$ make all
```
Then, create a tap interface (to which RIOT will connect):
```
$ sudo ip tuntap add tap0 mode tap user ${USER}
$ sudo ip link set tap0 up
```
Run the resulting RIOT binary by invoking:
```
$ make term
```
The application is now listening on all it's configured IP addresses.
Now find out its link\_layer address:
```
$ make term
/home/kaspar/src/riot/examples/microcoap_server/bin/native/microcoap_server.elf tap0
RIOT native interrupts/signals initialized.
LED_GREEN_OFF
LED_RED_ON
RIOT native board initialized.
RIOT native hardware initialization complete.
main(): This is RIOT! (Version: 2015.12-devel-632-g8f451-booze-add_conn_coap_example)
RIOT microcoap example application
Waiting for address autoconfiguration...
Configured network interfaces:
Iface 5 HWaddr: 96:3c:18:1e:26:f7
MTU:1500 HL:64 RTR RTR_ADV
Source address length: 6
Link type: wired
inet6 addr: ff02::1/128 scope: local [multicast]
inet6 addr: fe80::e42a:1aff:feca:10ec/64 scope: local
inet6 addr: ff02::1:ffca:10ec/128 scope: local [multicast]
inet6 addr: ff02::2/128 scope: local [multicast]
inet6 addr: 2001:db8:1:0:e42a:1aff:feca:10ec/64 scope: global
Waiting for incoming UDP packet...
```
The link-layer address in this case is "fe80::e42a:1aff:feca:10ec", the only
"scope: local" address set.
Testing
=======
There are multiple external CoAP clients you can use to test the server on native.
libcoap CLI
-----------
(replace "fe80::e42a:1aff:feca:10ec" with your link-layer address)
```
# coap-client "coap://[fe80::e42a:1aff:feca:10ec%tap0]/riot/board"
```
Copper (Firefox Plugin)
-----------------------
The Copper plugin for Firefox provides you with a nice graphical interface, but
getting it to work with RIOT requires a little setup.
Make sure you've installed
- The [Firefox Copper plugin](https://addons.mozilla.org/en-US/firefox/addon/copper-270430/)
- The Router Advertisement Daemon (radvd)
And build the application again using `make`.
Enter the following into your `/etc/radvd.conf` (if it doesn't exist yet, create one):
```
interface tap0
{
AdvSendAdvert on;
MinRtrAdvInterval 3;
MaxRtrAdvInterval 10;
AdvDefaultPreference low;
prefix 2001:db8:1:0::/64
{
AdvOnLink on;
AdvAutonomous on;
AdvRouterAddr off;
};
};
```
(you can use `radvd -c` to check for syntax errors)
and run
```
sudo radvd
```
Then, run the RIOT binary as usual:
```
make term
```
Note that the output listing all configured interfaces contains a globally scoped
address, which you can now use to reach the RIOT instance via Copper. To do so, enter this:
```
coap://[2001:db8:1:0:e42a:1aff:feca:10ec]/riot/board
```
into your Firefox address bar, where you should replace `2001:db8:1:0:e42a:1aff:feca:10ec`
with your RIOT instance's address marked as "scope: **global**".
If you click the big green `GET` button, the word `native` should appear in the
**Payload** text box at the center of the GUI.
**If this doesn't work,** try manually adding a Global address to the tap0 interface:
```
sudo service radvd start
sudo ip address add 2001:db8:1::a/64 dev tap0
make term
```
