# CC13xx/CC26xx Very Sleepy Demo
|
||||||
|
|
||||||
|
This example demonstrates a way of deploying a very low-consuming, very sleepy
|
||||||
|
node. The node has two modes of operation:
|
||||||
|
|
||||||
|
* Normal: ContikiMAC duty-cycles the radio as usual. The node is reachable.
|
||||||
|
* Very Sleepy: Radio cycling mostly off, except when we need to perform network
|
||||||
|
maintenance tasks. In this mode, the node is unreachable for most of the time.
|
||||||
|
|
||||||
|
The node will operate in RPL leaf mode. This means that it will be reachable
|
||||||
|
downwards, but it will not advertise the DODAG and it will not participate in
|
||||||
|
routing.
|
||||||
|
|
||||||
|
After booting, the node will enter "normal" mode.
|
||||||
|
|
||||||
|
The node exposes an OBSERVEable CoAP resource. It will notify subscribers with
|
||||||
|
a new value for this resource every `interval` seconds. It will then stay in
|
||||||
|
normal mode for `duration` seconds. During this time window, it will be
|
||||||
|
reachable over the network in order to e.g. receive a new configuration.
|
||||||
|
When this time window expires, the node will switch back to very sleepy mode.
|
||||||
|
This will only happen if very sleepy mode has been enabled by setting `mode=1`
|
||||||
|
as per the instructions below.
|
||||||
|
|
||||||
|
When the node is duty-cycling the radio, either because it is in normal mode or
|
||||||
|
because network maintenance is taking place, it will keep its green LED on thus
|
||||||
|
providing an indication that it is reachable.
|
||||||
|
|
||||||
|
A normal mode stint can be manually triggered by pressing the left button.
|
||||||
|
|
||||||
|
## Requirements
|
||||||
|
|
||||||
|
To run this example you will need:
|
||||||
|
|
||||||
|
* A border router operating with the same RDC, same channel, same radio mode
|
||||||
|
(e.g. IEEE or sub-ghz), same PAN ID. Alternatively, you can
|
||||||
|
use [6lbr](https://github.com/cetic/6lbr) with a suitable slip-radio.
|
||||||
|
* The [Copper (Cu)](https://addons.mozilla.org/en-US/firefox/addon/copper-270430/)
|
||||||
|
addon for Firefox
|
||||||
|
|
||||||
|
## Configuration
|
||||||
|
|
||||||
|
To configure the node, send a CoAP POST message to the `very_sleepy_config`
|
||||||
|
resource. The POST message's payload must specify _at least one_ of:
|
||||||
|
|
||||||
|
* `mode=0|1`: Send `mode=1` to enable very sleepy mode, `mode=0` to disable it.
|
||||||
|
* `interval=n` where `n` is the number of seconds between two consecutive normal
|
||||||
|
mode periods. This interval also dictates the OBSERVEr notification period.
|
||||||
|
* `duration=n` where `n` is the number of seconds that the node will stay in
|
||||||
|
normal mode before dropping to very sleepy mode. This value is only relevant
|
||||||
|
if `mode==1`.
|
||||||
|
|
||||||
|
A POST request must contain at least one of the above, but they are otherwise
|
||||||
|
all optional. So, for example, a POST may simply specify `interval=n`. To send
|
||||||
|
multiple values, delimit them with `&`. So you can send something like
|
||||||
|
`mode=1&interval=60&duration=20`
|
||||||
|
|
||||||
|
The current running configuration can be retrieved by sending a GET request to
|
||||||
|
the same CoAP resource.
|
||||||
|
|
||||||
|
## Running the example
|
||||||
|
|
||||||
|
* Deploy your border router or 6lbr
|
||||||
|
* Turn on the very sleepy node.
|
||||||
|
* Fire up the Copper addon
|
||||||
|
* Select `.well-known/core` and hit `GET`
|
||||||
|
* Configure very sleepy operation:
|
||||||
|
* Select the `very_sleepy_config` resource
|
||||||
|
* In the `Outgoing` pane, type your POST payload as per the instructions
|
||||||
|
above. For example, you can type: `mode=1&interval=30&duration=10`
|
||||||
|
* Hit `POST`
|
||||||
|
* Select the `sen/readings` resource and hit `OBSERVE`
|
||||||
|
|
||||||
|
## Caveats
|
||||||
|
|
||||||
|
If you click on a resource in the Copper resources tree while you are observing
|
||||||
|
a different resource, the OBSERVEr for the latter will be stopped without
|
||||||
|
notifying the CoAP server. This will result in the server sending out OBSERVE
|
||||||
|
notifications that will be responded to with port unreachable ICMPv6 messages.
|
||||||
|
This will continue for quite a while, until the server detects that the
|
||||||
|
OBSERVEr has been lost (a test currently performed once every 20 notifications).
|
||||||
|
In order to prevent this from happening, hit the "Cancel" button for the
|
||||||
|
OBSERVE before switching views to a different resource. This will unregister
|
||||||
|
the observer.
|
||||||
|
|
||||||
|
In very sleepy mode, the radio is not truly always off. The contiki core needs
|
||||||
|
to perform other periodic tasks in order to maintain network connectivity. For
|
||||||
|
that reason, this example will allow the radio to turn on periodically even
|
||||||
|
while in very sleepy mode. Thus, you may see that the node becomes briefly
|
||||||
|
reachable every now and then. However, do not count on those periods of
|
||||||
|
reachability to perform any tasks, as they will be brief and will be disrupted
|
||||||
|
without warning.
