}
catch (e) {
alert('<setup> ' +e);
}
}
function cellid(){
var entity = "Network";
var key = "CellID";
var criteria = new Object();
criteria.Entity = entity;
criteria.Key = key;

try {
var result = so.ISysInfo.GetInfo(criteria);

}
}

I have the same issue.

When requesting:

Entity="Network"
Key="CurrentNetwork"

within the criteria object, only the following properties come back
with valid data:

NetworkName
NetworkStatus = 1
NetworkMode
CountryCode (MCC)
NetworkCode (MNC)

LocationStatus comes back as "true" which indicates AreaCode (LAC) and
CellId are valid, but when printed to debug all they contain is:

AreaCode = undefined
CellId = undefined

I was not able to access the "CellID" property directly which is why
I am reading "CurrentNetwork" which returns all of the above parameters,
but only with an async callback.

For example:

  var criteria = new Object();
  criteria.Entity = "Network";
  criteria.Key = "CurrentNetwork";

  try {
    so.ISysInfo.GetInfo(criteria, locCallback);
  }
  catch {}


 function locCallback(transId, eventCode, result)
 {
    showObject(result.ReturnValue);
 }

The documentation seems to suggest that you cannot read the
LAC and CellID directly with GetInfo(), but that they can
be read with GetNotification(), although I've not had
any success with this yet either.

I have had some success with this. The following code does work but you only get an alert when the "CellID" changes which is not as useful as being able to read the current "CellID".

function getCellID()
{
  var criteria = new Object();
  criteria.Entity = "Network";
  criteria.Key = "CellId";

  try
  {
    var result = so.ISysInfo.GetNotification(criteria, cellCallback);
  }    

  catch (e)
  {
    alert ("Exception: " + e);
  }  
}

function cellCallback(transId, eventCode, result)
{
  alert(result.ReturnValue.Status);
}

If you try to use

so.ISysInfo.GetInfo

instead of

so.ISysInfo.GetNotification

what you get is an exception with the text "Error: invalid transaction id".

Hi Jasper,

it doesn't work because it's a asynchronous method. The code below will help you.

function getCELLID(){
    try {
        var so = device.getServiceObject("Service.SysInfo", "ISysInfo");
        var criteria = new Object();
        criteria.Entity = 'Network';
        criteria.Key = 'CellID';
        alert("GetCellID")
        
        var result = so.ISysInfo.GetNotification(criteria, function(transId, eventCode, result){
        
            if (eventCode == 4) {
                alert("Error " + result.ErrorCode + ": " + result.ErrorMessage);
                return;
            }
            alert("ok");
            alert(result);
            alert(result.ReturnValue);
            alert(result.ReturnValue.Status);
        });
    } 
    catch (e) {
        return null;
    }
}

Thank you for the code! But... how to use this?
Just calling getCELLID() doesn't work...

Thanks!
