Hello.

When i send a long sms by nntp, it work fine with now sms.

but i saw the debug file and i want to understand what he does.

I just send a long sms and it put 05 00 03 3B 02 01 at the begining of the field "short_message" juste after the field "sm_length" for the first part of the sms

and 05 00 03 3B 02 02 for the second part of the sms.

Someone now how nowsms calculate the value tu put at the begining of the sms for long sms ?

(and if i can find documents on the net that explain that)

Thank you very much for your help.

Michel,

The 3B octet is the reference number for that message. It can be any value, as long as it is the same for every PDU that makes up that message.

Hi,
Im writing an application that uses smpp 3.4, to perform concatenation, through UDH. Am setting esm_class to hex40, dcs to 0, and placing the UDH in the short_message field (the content follows the udh as plain text). Note that i use a 16-bit reference no for concatenation.
NowSMS is breaking the first message again and placing its own UDH at that point, even though there is no reason for it to do so (the text content is less than 152 characters). Thus im receiving back onto the handset 3 messages instead of 2.
Any known issues/workarounds?
Thanks.
