OPEN HTTP, WebSocket, MQTT, & CoAP COMMUNICATIONS NETWORK & API FOR THE INTERNET OF THINGS (IoT)!

Visit developer.octoblu.com for up-to-the-latest documentation and screencasts.

Introduction

Meshblu is an open source machine-to-machine instant messaging network and API. Our API is available on HTTP REST, realtime Web Sockets via RPC (remote procedure calls), MQTT, and CoAP. We seamlessly bridge all of these protocols. For instance, an MQTT device can communicate with any CoAP or HTTP or WebSocket connected device on Meshblu.

Meshblu auto-assigns 36 character UUIDs and secret tokens to each registered device connected to the network. These device "credentials" are used to authenticate with Meshblu and maintain your device's JSON description in the device directory.

Meshblu allows you to discover/query devices such as drones, hue light bulbs, weemos, insteons, raspberry pis, arduinos, server nodes, etc. that meet your criteria and send IM messages to 1 or all devices.

You can also subscribe to messages being sent to/from devices and their sensor activities.

Meshblu offers a Node.JS NPM module called Meshblu and a meshblu.js file for simplifying Node.JS and mobile/client-side connectivity to Meshblu.

Installing/Running Meshblu private cloud

Clone the git repository, then:

$ npm install

Meshblu uses Mongo, Redis, ElasticSearch, and Splunk; however, we have made this infrastructure optional for you. Meshblu falls back to file system and memory storage if these services are not configured allowing you to deploy a private Meshblu cloud to a Raspberry Pi or other mini-computer!

If you want to include these services for a scalable infrastructure, you can make the following changes to your config.js file.

Modify config.js with your MongoDB connection string. If you have MongoDB running locally use:

mongo: {
  databaseUrl: "mongodb://localhost:27017/skynet"
},

You can also modify config.js with your Redis connection information. If you have Redis running locally use:

redis: {
  host: "127.0.0.1",
  port: "6379",
  password: "abcdef"
},

You can also modify config.js with your ElasticSearch connection information. If you have ES running locally use:

elasticSearch: {
  host: "localhost",
  port: "9200"
},

If you would like to connect your private Meshblu cloud to meshblu.octoblu.com or another private Meshblu cloud, register a UUID on the parent cloud (i.e. meshblu.octoblu.com) using the POST /Devices REST API and then add the returned UUID and token to the following section to your private cloud's config.js file:

parentConnection: {
  uuid: 'xxxx-my-uuid-on-parent-server-xxxx',
  token: 'xxx ---  my token ---- xxxx',
  server: 'meshblu.octoblu.com',
  port: 80
},

Start the Meshblu server running HTTP and WebSocket protocols use:

$ node server.js --http

You may also run something like forever to keep it up and running:

$ forever start server.js --http

MQTT Broker

MQTT is an optional Meshblu protocol. If you would like to run our MQTT broker with your private Meshblu cloud, open another console tab and run:

$ node server.js --http --mqtt

or using forever

$ forever start server.js --http --mqtt

Note: Our MQTT Broker defaults to using Mongo; however, you can run it in memory by removing the databaseUrl from the config.js.

mqtt: {
  port: 1883,
  skynetPass: "Very big random password 34lkj23orfjvi3-94ufpvuha4wuef-a09v4ji0rhgouj"
}

CoAP

CoAP is an optional Meshblu protocol. If you would like to run our CoAP protocol with your private Meshblu cloud, open another console tab and run:

$ node server.js --http --coap

or using forever

$ forever start server.js --http --coap

Note: Our CoAP protocol defaults to using Mongo; however, you can run it in memory by removing the databaseUrl from the config.js.

coap: {
  port: 5683,
  host: "localhost"
}

Heroku

Use the button above to deploy to the Heroku cloud for Free! Starts out with a basic implementation of Meshblu with only MongoDB. The app.json / config.js can be modified to allow for more protocols and storage systems.

Heroku allows you scale with a touch of a button.

DigitalOcean

Use the button above to deploy to the DigitalOcean cloud for as little as $5/month! The app.json / config.js can be modified to allow for more protocols and storage systems.

Docker

The default Dockerfile will run Meshblu a container to make quick experiments easier. The easiest way to get started is to use our image from the docker registry:

docker run -e TOKEN=something_secret octoblu/meshblu

A note about secrets: We require that whomever runs Meshblu to supply a text secret, in the form of the TOKEN environmnet variable, that we can use as a salt when hashing tokens. Not knowing this secret hinders a malicious user when creating a rainbow table to reverse the hashed tokens.

If you want to build your own image, then run the following from the Meshblu project root:

docker build -t local/meshblu .

Then run it like above, but with the local image:

docker run -e TOKEN=something_secret local/meshblu

This will run Meshblu (formerly skynet) and expose port 80 from the container and map it to your port 80. If you'd like to map it to a different port, use -p. For example, to map it to local port 3000:

docker run -p 3000:80 -e TOKEN=something_secret local/meshblu

Nodeblu Developer Toolkit

Play with Meshblu IoT platform in Chrome! Nodeblu helps you experiment with the Octoblu and Meshblu Internet of Things platforms by dragging, dropping, and wiring up various nodes connected to Meshblu!

Nodeblu is Octoblu's fork of the popular NodeRED application from IBM. Since our app is deployed as a Chrome extension, we decided to add extra local features such as speech recognition and text-to-speech, a WebRTC webcam, HTML5 notifications, access to ChromeDB, a gamepad controller, and access to local and remote Arduino and Spark devices via our Microblu OS.

Gateblu

We have an open source Octoblu Gateway also available on GitHub. Our Gateway allows you to connect devices with or without IP addresses to Meshblu and communicate bi-directionally! The Gateway uses WebSockets to connect to Meshblu so it can traverse NAT firewalls and send/receive messages to/from Meshblu.

Gateblu has an extensible plugin architecture allowing you to create plugins for devices that we have not had a chance to connect yet. You can search NPMJS.org for a list of active Gateblu plugins.

Microblu Operating System

Meshblu includes a micro-controller operating system that is compatible with Arduino, Spark, and Pinoccio! The OS is available on GitHub and comes with firmata built-in.

On power-on, the Microblu OS connects to Meshblu, obtains a UUID, and awaits your instructions! You can message the micro-controller to turn on/off pins and servos as well as request streaming analog sensor data from various pins.

HTTP(S) REST API

Most of our API endpoints require authentication credentials (UUID and secret token) passed in the HTTP headers as meshblu_auth_uuid and meshblu_auth_token respectively. These credentials are generated by registering a device or user with Meshblu via the POST /Devices API (see below). If you would like to associate additional Meshblu devices with the UUID and Token that you created (as a user), you can add an "owner" property to your other devices with the user's UUID as its value; otherwise, you can use the device's UUID and token in the headers to control the device itself.

We support the following device permissions: Discover, Send Messages, Receive Messages (subscribe) and Configure (Update). These permissions are manageable by adding UUIDs to whitelists and blacklists arrays with the following names: discoverWhitelist, discoverBlacklist, sendWhitelist, sendBlacklist, receiveWhitelist, receiveBlacklist, updateWhitelist, updateBlacklist. Note: If your UUID is the same as the "owner" UUID, these permissions are not enforced (you are the owner).

socket.emit('getdata', {"uuid":"b5535950-29fd-11e3-9113-0bd381f0b5ef", "token": "2ls40jx80s9bpgb9w2g0vi2li72v5cdi", "limit": 1}, function (data) {
  console.log(data);
});

Request and receive a message broadcast

// sending message to all devices
socket.emit('message', {"devices": "all", "message": {"yellow":"on"}});

// sending message to a specific devices
socket.emit('message', {"devices": "b5535950-29fd-11e3-9113-0bd381f0b5ef", "message": {"yellow":"on"}});

// sending message to an array of devices
socket.emit('message', {"devices": ["b5535950-29fd-11e3-9113-0bd381f0b5ef", "ad698900-2546-11e3-87fb-c560cb0ca47b"], "message": {"yellow":"on"}});

Websocket API commands include: status, register, unregister, update, whoami, devices, subscribe, unsubscribe, authenticate, and message. You can send a message to a specific UUID or an array of UUIDs or all nodes on SkyNet.

MQTT API

Our MQTT API works similar to our WebSocket API. In fact, we have a skynet-mqtt NPM module for to simplify client-side MQTT connects with SkyNet.

$ npm install skynet-mqtt

Here are a few examples:

var skynet = require('skynet-mqtt');

var conn = skynet.createConnection({
  "uuid": "xxxxxxxxxxxx-My-UUID-xxxxxxxxxxxxxx",
  "token": "xxxxxxx-My-Token-xxxxxxxxx",
  "qos": 0, // MQTT Quality of Service (0=no confirmation, 1=confirmation, 2=N/A)
  "host": "localhost", // optional - defaults to meshblu.octoblu.com
  "port": 1883  // optional - defaults to 1883
});

conn.on('ready', function(){

  console.log('UUID AUTHENTICATED!');

  //Listen for messages
  conn.on('message', function(message){
    console.log('message received', message);
  });


  // Send a message to another device
  conn.message({
    "devices": "xxxxxxx-some-other-uuid-xxxxxxxxx",
    "payload": {
      "skynet":"online"
    }
  });


  // Broadcast a message to any subscribers to your uuid
  conn.message({
    "devices": "*",
    "payload": {
      "hello":"skynet"
    }
  });


  // Subscribe to broadcasts from another device
  conn.subscribe('xxxxxxx-some-other-uuid-xxxxxxxxx');


  // Log sensor data to skynet
  conn.data({temperature: 75, windspeed: 10});

});

300 = Incoming message
301 = Incoming SMS message
302 = Outgoing SMS message
303 = Incoming Yo message
304 = Outgoing Yo message
305 = Outgoing Push Notification message
400 = Register device
401 = Update device
402 = Delete device
