Connman-simplified NPM

Connman simplified

Node.js package that simplifies Connman (Opensource connection manager) usage. Enables you to easilly control connections over wifi and ethernet. Get realtime status changes. Uses Connman-api package internally. Connman: http://www.connman.net/

Abstracts Connman API making your code shorter and simpler.
Includes network cache system (for when scanning is impossible in hotspot mode).
Uses regular Node.js naming conventions.

Examples

Try to connect to favorite wifi network, if fails become hotspot. Log the wifi state changes.

var connman = require('connman-simplified')();
connman.init(function(err) {
  connman.initWiFi(function(err,wifi,properties) {
  
    if(!properties.connected) { // not yet connected? 
      wifi.joinFavorite(function(err) {
        if(err) wifi.openHotspot();
      });
    }
    wifi.on('state',function(value) {
      console.log("WiFi state change: ",value);
    });
    
  });
});

Join specific network, disconnect after 5 seconds.

var connman = require('connman-simplified')();
connman.init(function(err) {
  connman.initWiFi(function(err,wifi,properties) {
  
    wifi.join("myhomenetwork",'myPassphrase');
    
    setTimeout(function() {
      wifi.disconnect();
    },5000);
    
  });
});

Open a hotspot, get cached available networks, close after 5 seconds, get fresh available networks. Retrieving networks from cache is usefull because usually hardware can't scan while being hotspot.

var connman = require('connman-simplified')();
connman.init(function(err) {
  connman.initWiFi(function(err,wifi,properties) {
    
    wifi.openHotspot("myhotspot","aPassphrase",function(err) {
      // get cached available networks (collected earlier)
      wifi.getNetworksCache(function(err,list) {
        console.log("networks from cache: ",list);
      });
      
      setTimeout(function() {
        wifi.closeHotspot(function(err) {
          // get fresh available networks
          wifi.getNetworks(function(err,list) {
            console.log("networks: ",list);
          });
        });
      },5000);
    });
    
  });
});

Get a more readable networks list. Uses common Connman services format, see: https://01.org/connman/documentation

var connman = require('connman-simplified')();
connman.init(function(err) {
  connman.initWiFi(function(err,wifi,properties) {
    
    wifi.getNetworks(function(err,list) {
      // get more readable list using getServicesString:
      console.log("networks: ",wifi.getServicesString(list));
    });
    
  });
});

Bigger interactive example is included.
