I read the Nokia documents about concatenated SMS messages, checked the FAQs, searched the Web, but I still cannot send it successfully.
Here is what I understood:
-I have to set TP-UDHI to 1 for all SMS parts
-I have to add before User Data five octets:
00 - meaning concatenated SMS
03 - data length
xx - reference number
yy - number of SMS messages
zz - sequential number of current message
All above octets should be 7 bit coded. What about use data length? Should it be equal to user data only, or should it include also these 5 octets?
Can anyone send me a sample of sending such SMS messages step by step with detailed SMS parts - for dummies
Thanks in advance...
