Use dbus-native to call NetworkManager

[zhangtianye]

I've meet some problem when I try to use dbus-native with nodejs to call to NetworkManager and let NetworkManager connect to a SSID(WIFI).
I use the connection is :

con = [ //a
  ['802-11-wireless', [
    ['mode', ['s','infrastructure']],
    ['security', ['s','802-11-wireless-security']],
    ['ssid', ['y',stringToArrayOfBytes('TP-LINK_10DC')]]
  ]],
  ['802-11-wireless-security', [
    ['auth-alg', ['s','open']], 
    ['key-mgmt', ['s','wpa-psk']],
    ['psk', ['s','0123456789']]
  ]],
  ['connection',[
    ['id', ['s','TP-LINK_10DC']],
    ['type', ['s','802-11-wireless']],
    ['uuid', ['s',uuid.v1().toString()]]
  ]],
    ['ipv4', [
        ['method', ['s','auto']]
    ]],
    ['ipv6', [
    ['method', ['s','auto']]
        ]]
]

and my code is:

var dbus = require('dbus-native');
var systemBus = dbus.systemBus();
var uuid = require('uuid');

var stringToArrayOfBytes = function (str) {
  var bytes = [];
  for (var i = 0; i < str.length; ++i) {
      bytes.push(str.charCodeAt(i));
  }
  return bytes;
};
con = [ //a
  ['802-11-wireless', [
    ['mode', ['s','infrastructure']],
    ['security', ['s','802-11-wireless-security']],
    ['ssid', ['ai',stringToArrayOfBytes('TP-LINK_10DC')]]
  ]],
  ['802-11-wireless-security', [
    ['auth-alg', ['s','open']], 
    ['key-mgmt', ['s','wpa-psk']],
    ['psk', ['s','0123456789']]
  ]],
  ['connection',[
    ['id', ['s','TP-LINK_10DC']],
    ['type', ['s','802-11-wireless']],
    ['uuid', ['s',uuid.v1().toString()]]
  ]],
 ['ipv4', [
 ['method', ['s','auto']]
 ]],
 ['ipv6', [
    ['method', ['s','auto']]
        ]]
]
systemBus.getService('org.freedesktop.NetworkManager').getInterface(
 '/org/freedesktop/NetworkManager',
 'org.freedesktop.NetworkManager', function(err, Device) {
// console.log(Device);
 Device.AddAndActivateConnection(con,'/org/freedesktop/NetworkManager/Devices/0','/',function(err,id){
 console.log(id);
 });

});

In my code,SSID is the name of WIFI,and psk is my password.ID is also the name of WIFI.But id can use the form of string,ssid should use the form of bytes.
What can I do to help me Connect to a SSID?
Thanks.

currently when you serialise/deserialise variant, it's always a struct no matter if underlying type is simple or compound. Examples:

   // sv where v is "ai
   [ "string", [ "ai" [ [ 1, 2, 3 ] ] ]

   // av , first is ai, second is "sai"
   [  [ "ai", [ [1, 2, 3 ] ] ],   [ "sai", [ "test", [ 1, 2, 3 ] ] ]

so your code should be

var dbus = require('dbus-native');
var systemBus = dbus.systemBus();
var uuid = require('uuid');

var stringToArrayOfBytes = function (str) {
  var bytes = [];
  for (var i = 0; i < str.length; ++i) {
      bytes.push(str.charCodeAt(i));
  }
  return bytes;
};
con = [ //a
  ['802-11-wireless', [
    ['mode', ['s','infrastructure']],
    ['security', ['s','802-11-wireless-security']],
    ['ssid', ['ai', [ stringToArrayOfBytes('TP-LINK_10DC') ] ]]  // note that array itself is element of struct
  ]],
  ['802-11-wireless-security', [
    ['auth-alg', ['s','open']], 
    ['key-mgmt', ['s','wpa-psk']],
    ['psk', ['s','0123456789']]
  ]],
  ['connection',[
    ['id', ['s','TP-LINK_10DC']],
    ['type', ['s','802-11-wireless']],
    ['uuid', ['s',uuid.v1().toString()]]
  ]],
 ['ipv4', [
 ['method', ['s','auto']]
 ]],
 ['ipv6', [
    ['method', ['s','auto']]
        ]]
]
systemBus.getService('org.freedesktop.NetworkManager').getInterface(
 '/org/freedesktop/NetworkManager',
 'org.freedesktop.NetworkManager', function(err, Device) {
// console.log(Device);
 Device.AddAndActivateConnection(con,'/org/freedesktop/NetworkManager/Devices/0','/',function(err,id){
 console.log(id);
 });

});

The Ssid which I want to send to NetworkManager is a " GByteArray " data structure.
I tried to use the form of 'ai' ,but I get error : " ["A 'wireless' setting with a valid SSID is required if no AP path was given."] ",Maybe the Data Structure is not right.
Can you give me some more advices?
