Object Usage Examples

Sample 1

This is a sample to get and display own WiFi MAC address.

nqWiFi.getIDs(function(id){
  print(id.macAddr);
});

Sample 2

This is a sample that acquires and displays the connected WiFi-AP information.

nqWiFi.getSignalQuality(function(sq){
  print("MAC  --> " + sq.macAddr);
  print("SSID --> " + sq.ssid);
  print("RSSI --> " + sq.rssi);
});

Sample 3

This is a sample that acquires and displays nearby WiFi-AP information.

nqWiFi.getScanList(function(aplist){
  if (false != aplist.result) {
    for(n = 0; n < aplist.length; n++) {
      print("-----");
      print("MAC  --> " + aplist[n].macAddr);
      print("SSID --> " + aplist[n].ssid);
      print("RSSI --> " + aplist[n].rssi);
    }
  }
});
