rpi-wifi-connection

Module to connect a Raspberry Pi to Wi-Fi

Installation

$ npm install rpi-wifi-connection --save

Usage

var Wifi = require('rpi-wifi-connection');
var wifi = new Wifi();

Methods

constructor(iface)

Constructs a new wifi connection object.

• iface - Specifies the name of the interface (default is wlan0)

connect(options)

Connects to the specified network.

• options.ssid - Specifies the network name.
• options.psk - Specifies the password.
• options.timeout - Specifies the number of milliseconds to wait for connection. Default is 60 seconds (60000).
• options.hidden - Should be set to true if the network is hidden.

var Wifi = require('rpi-wifi-connection');
var wifi = new Wifi();

wifi.connect({ssid:'my-network', psk:'raspberry'}).then(() => {
    console.log('Connected to network.');
})
.catch((error) => {
    console.log(error);
});

scan()

Return a promise containing the available networks

var Wifi = require('rpi-wifi-connection');
var wifi = new Wifi();

wifi.scan().then((ssids) => {
    console.log(ssids);
})
.catch((error) => {
    console.log(error);
});

// [ { bssid: 'f4:ca:e5:e7:de:58', signalLevel: -72, frequency: 2467, ssid: 'homo' },
  { bssid: 'f4:ca:e5:e7:de:5a', signalLevel: -72, frequency: 2467, ssid: 'deus' } ]

getStatus()

Returns a promise containing the network status.

var Wifi = require('rpi-wifi-connection');
var wifi = new Wifi();

wifi.getStatus().then((status) => {
    console.log(status);
})
.catch((error) => {
    console.log(error);
});

// { ssid: 'Julia', ip_address: '10.0.1.189' }

getState()

Returns a promise containing the connection state. Please note that this only returns the connection state of your Raspberry Pi for any network. To see if you are connected to a specific network, use getStatus().

var Wifi = require('rpi-wifi-connection');
var wifi = new Wifi();

wifi.getState().then((connected) => {
    if (connected)        
        console.log('Connected to network.');
    else
        console.log('Not connected to network.');
})
.catch((error) => {
    console.log(error);
});

getNetworks()

Returns a promise containing a list of Wi-Fi networks.

var Wifi = require('rpi-wifi-connection');
var wifi = new Wifi();

wifi.getNetworks().then((networks) => {
    console.log(networks);
});

//  [ { id: 0, ssid: 'Julia' } ]
