Node dbus-native - Passing Passphrase while connecting to WiFi service using connMan

Question

Hi I have been having this problem for the last couple of days, while trying to connect to a protected WiFi network using dbus. So the code I have developed so far is:

Register Agent

var dbus = require('dbus-native');
var bus = dbus.systemBus();
bus.invoke({
        destination: 'net.connman',
        path: '/',
        'interface': 'net.connman.Manager',
        member: 'RegisterAgent',
        type: dbus.messageType.methodCall,
        signature: 'o',
        body: [
                '/test/agent'
        ]
}, function(error, response) {
        if (error) {
                console.error('Error', error);
                //process.exit(1);
        } else {
                console.info('Success', response);
               // process.exit(0);
        }
});

Output

> Success

Scan Wifi

var dbus = require('dbus-native');
var bus = dbus.systemBus();
bus.invoke({
        destination: 'net.connman',
        path: '/net/connman/technology/wifi',
        'interface': 'net.connman.Technology',
        member: 'Scan',
        type: dbus.messageType.methodCall,
}, function(error, response) {
        if (error) {
                console.error('Error', error);
                //process.exit(1);
        } else {
                console.info('Success', response);
                //process.exit(0);
        }
});

Output

> Success

Connect to WiFi Service

var dbus = require('dbus-native');
var bus = dbus.systemBus();
bus.invoke({
        destination: 'net.connman',
        path: '/net/connman/service/wifi_00e04c81923e_4469676957494649_managed_psk',
        'interface': 'net.connman.Service',
        member: 'Connect',
        type: dbus.messageType.methodCall,
}, function(error, response) {
        if (error) {
                console.error('Error', error);
                //process.exit(1);
        } else {
                console.info('Success', response);
                //process.exit(0);
        }
});

Output

> Error ['Invalid Arguments']

Output fropm connMan logs

So basically, I would greatly appreciate it if someone could show me how to pass back the user data containing the passphrase for the WiFi network.

Any help would be greatly appreciated? (connMan version 1.20)

Thanks

I was unable to get dbus-native to work.

My solution was to create a wifi.config file in /lib/connman/ which contains the passphrase for each service:

wifi.config example

[service_wifi_00e04c819295_4469679972434649_managed_psk] 
Type = wifi
Security = wpa2 
Name = [service_] 
Type = wifi 
Security = wpa2 
Name = WiFiAP
Passphrase = 12345

Then simply used dbus-native to connect to the WiFi service:

Connect

var dbus = require('dbus-native');
var bus = dbus.systemBus();
bus.invoke({
        destination: 'net.connman',
        path: '/net/connman/service/wifi_48022aca514f_4469676957494649_managed_psk',
        'interface': 'net.connman.Service',
        member: 'Connect',
        type: dbus.messageType.methodCall,
}, function(error, response) {
        if (error) {
                console.error('Error', error);
                //process.exit(1);
        } else {
                console.info('Success', response);
                //process.exit(0);
        }
});
