SMPP message length error using jamaa more than 160 characters - asp.net

Question

I am using jamaa-smpp to send sms. But I am not able to send more than 160 characters using the api. I am using the following link http://jamaasmpp.codeplex.com/
The code is as follows
SmppConnectionProperties properties = _client.Properties;
properties.SystemID = "test";
properties.Password = "test1";
properties.Port = 101; //IP port to use
properties.Host = "..."; //SMSC host name or IP Address
....
Is it possible to send more than 160 character using that API.

I found the solution it was there on the website discussion. I am posting it here so that one can find solution here.
I replaced the existing function in the TextMessage.cs (JamaaTech.Smpp.Net.Client).
The function name is IEnumerable<SendSmPDU> GetPDUs(DataCoding defaultEncoding)
//protected override IEnumerable<SendSmPDU> GetPDUs(DataCoding defaultEncoding)
//{
// //This smpp implementation does not support sending concatenated messages,
// //however, concatenated messages are supported on the receiving side.
// int maxLength = GetMaxMessageLength(defaultEncoding, false);
// byte[] bytes = SMPPEncodingUtil.GetBytesFromString(vText, defaultEncoding);
// //Check message size
// if(bytes.Length > maxLength)
// {
// throw new InvalidOperationException(string.Format(
// "Encoding '{0}' does not support messages of length greater than '{1}' charactors",
// defaultEncoding, maxLength));
// }
// SubmitSm sm = new SubmitSm();
// sm.SetMessageBytes(bytes);
// sm.SourceAddress.Address = vSourceAddress;
// sm.DestinationAddress.Address = vDestinatinoAddress;
// sm.DataCoding = defaultEncoding;
// if (vRegisterDeliveryNotification) { sm.RegisteredDelivery = RegisteredDelivery.DeliveryReceipt; }
// yield return sm;
//}
protected override IEnumerable<SendSmPDU> GetPDUs(DataCoding defaultEncoding)
{
SubmitSm sm = new SubmitSm();
sm.SourceAddress.Address = vSourceAddress;
sm.DestinationAddress.Address = vDestinatinoAddress;
sm.DataCoding = defaultEncoding;
if (vRegisterDeliveryNotification)
sm.RegisteredDelivery = RegisteredDelivery.DeliveryReceipt;
int maxLength = GetMaxMessageLength(defaultEncoding, false);
byte[] bytes = SMPPEncodingUtil.GetBytesFromString(vText, defaultEncoding);
if (bytes.Length > maxLength)
{
var SegID = new Random().Next(1000, 9999);
var messages = Split(vText, GetMaxMessageLength(defaultEncoding, true));
var totalSegments = messages.Count;
var udh = new Udh(SegID, totalSegments, 0);
for (int i = 0; i < totalSegments; i++)
{
udh.MessageSequence = i + 1;
sm.Header.SequenceNumber = PDUHeader.GetNextSequenceNumber();
sm.SetMessageText(messages[i], defaultEncoding, udh);
yield return sm;
}
}
else
{
sm.SetMessageBytes(bytes);
yield return sm;
}
}
private static List<String> Split(string message, int maxPartLength)
{
var result = new List<String>();
for (int i = 0; i < message.Length; i += maxPartLength)
{
var chunkSize = i + maxPartLength < message.Length ? maxPartLength : message.Length - i;
var chunk = new char[chunkSize];
message.CopyTo(i, chunk, 0, chunkSize);
result.Add(new string(chunk));
}
return result;
}
