Hi Raksa,
Sorry, I'm so overloaded this time.
But I try to solve your problem.
I need "Received Data" from your log.
Possible you disabled evReceiveData event in your code
Code: Select all
private void client_evReceiveData(object sender, byte[] data)
{
AddToLog("Received Data: "+ByteArrayToHexString(data));
}
Can you post here this invalid packet?

There are only "Sending Data:" lines, but I need "Received Data:" to analyze invalid packet.

3:55:57 PM: Invalid DELIVER_SM packet
[/code]

Both DELIVER_SM packets have enabled UDHI (User-Data-Header-Indicator)
but actually short_message field does not contain user data header.
How did you receive such messages?

I got nothing just only one part of sms like i told u. Does it's ok with ur library or it wrong because of my code? please i really need it.
Thanks,,

My library tries to find user data header in the short_message and it reports
"Invalid DELIVER_SM packet" when UDH cannot be found.
It is not problem in your code.
This problem comes from SMSC side. Please ask them why they send ems_class = 0x40 (which means UDHI is enabled), but short_message field does not contain UDH.

I don't know too but i try other library it can get all message. does it is problem with smsc?

Normal concatenated message should contain information about
1) msg_ref_num
2) total segments
3) sequence number
But your packets does not have such information neither in UDH nor in SAR parameters.
I'll think how to avoid "Invalid DELIVER_SM packet" in your second case.
But it is not normal for concatenated messages.

Yes I see that too when i debug ur code i don't get those 3 that why it not work. I need one thing only bec now i really need to complete my project. I just want to got all full sms(long sms) even it not concante. bec your sample can get only first message only.
Thanks,,

Your first message is 153 (0x99) bytes length and I believe it contains
"G-get up
O-open your eyes
O-out of your bed
D-day has risen
M-merry life
O-old dreams cum true
R-rise $ shine
N-new frnds
I-idea of life
N-nice future
G-"
and second message is 13 (0x0d) bytes length and it contains
"GOODDAY 4 U! "
And there is no sequence information. You won't be able to concatenate these messages into one message.
Are you able to combine these messages with other library?

I've fixed "Invalid DELIVER_SM packet" problem for your examples.
But again without ability to combine these two messages. I hope you understood why I can not provide this ability.
Please download last version.
