Tasks¶

Prio 1¶

[x] properly finish beradio-2 convenience in forwarding and manipulation code
[x] don’t pretend on nodeid=2, neither use it for documentation, use nodeid=999 instead!
[x] release management
[x] add software tests
[x] start with libberadio c++
[x] use sawtooth signal instead of random data for pretending
[x] maybe use a pronounceable label as gateway id
- https://github.com/greghaskins/gibberish
[x] use shorter unique id as gateway id
- http://www.anotherchris.net/csharp/friendly-unique-id-generation-part-1/
- http://www.anotherchris.net/csharp/friendly-unique-id-generation-part-2/
[x] send timestamp along, InfluxDB stores “2015-11-14T16:29:42.157025953Z”
[x] use “-mcall-prologues” for producing smaller binaries 7024
[o] –interval option for publishers
[o] Don’t decode empty strings: ERROR: Decoding BERadio version 2 data “” failed: not a valid bencoded string
[o] API docs do not work! https://hiveeyes.org/docs/beradio/api.html

Prio 2¶

[o] improve docs

[o] move some stuff out of README.rst, place into network.rst and also publish @ kotori-daq
[o] add docs/rationale about choosing Bencode with reference to JeeLabs
[o] aggregate all external http references into links.rst
[o] move stuff to Kotori, improve Hiveeyes use-case

[o] add graphviz picture via Sphinx extension “sphinx.ext.graphviz”:

.. graphviz::

    digraph fas_components {
        rankdir=TB;
        ranksep=1;
        node[shape="box", fontname="Verdana"];
        edge[fontname="Verdana"];
            "FAS" -> "Janitor";
            "FAS" -> "Unique Object Keys";
            "FAS" -> "Signed Objects";
            "Janitor"[shape=record, label="{ Janitor | Authentication }"];
            "Janitor" -> "Routing";
            "Janitor" -> "Piggyback Events";
            "Unique Object Keys"[shape=record, label="{ Unique Object Keys | Entity addressing }"];
            "Signed Objects"[shape=record, label="{ Signed Objects | { Authorization | Inter-Service-Communication } }"];
    }

[o] maybe also try Sphinx extensions “sphinxcontrib.seqdiag, sphinxcontrib.blockdiag or sphinxcontrib.nwdiag”,

see dev/vz/documentation/meta/src/conf.py
[o] improve inline docs
[o] integrate essentials from “parsing-c-headers.rst” into applications/lst.rst

[o] finish libberadio c++
- [o] avr-stl-1.1.2 and Embencode-+1
- [o] message sending
[o] properly handle profile => ruleset dispatching
[o] care about proper addressing: e.g. take address information completely out of the message, but use identifier from gateway instead!?
[o] refactor out topic computation from MQTTPublisher.publish_point
[o] take a look at https://docs.internetofthings.ibmcloud.com/messaging/payload.html

Prio 3¶

[o] docs: What about other bus systems, like WAMP? See also https://github.com/goeddea/scratchbox/blob/master/yun/serial_to_wamp.js
[o] make some slides

Prio 4¶

Generalize and split core functionality into separate package “mqttkit”. Host on mqttkit.org

mqttkit ideas¶

The message broker supports clients connecting with the HTTP protocol using a REST API. Clients can publish by sending a POST message to “<AWS IoT Endpoint>/topics/<url_encoded_topic_name>?qos=1”
use paho instead of mosquitto
integrate
use “standard” json payload: https://docs.internetofthings.ibmcloud.com/messaging/payload.html
beacons
- time
- weather
try to run on pypy, jitpy, cython, numba or ... to get tighter timings
