but i wonder how can i write UDH for a longer v-card such as when binary data is more than 128 byte.
i guessed
1. UDH is like:
%0B%05%04%23%F4%00%00%00%03%00%02%01
but i dont understand all fields:
%0B :length of UDH
%05 :length of User data string
%04: length of port address string
%23%F4 : source port address
%00%00 : receiver port address
%00 : DONT KNOW WHAT IT IS
%03 : DONT KNOW WHAT IT IS
%00 : Some kind of reference ID but DONT KNOW WHAT IT IS
%02 : how many messages includes all message
%01 : 1.st message of 2 messages
Can anyone help me know what are those fields that i dont know pls...
Thanks in advance...
