Does enybody know how to represent 16 bit reference number for concatenated short message! "CIMD and Smart Messanging" doesn't contain information about it? There is olny information about 8 bit refernece number?
For 16 bit reference we need 2 octets. Is this the same idea like in 16 pport adressing?
For instance, for 1234 and 5678 port, part of UDH (032) looks like this:
05 04 12 34 56 78?
So there is spliting 4 digits into 2 octets! So there is no hex representation in fact!
To represent 8 bit reference we use hex. For instance
10 is in fact 0A!
So, how to represent 16 bit reference?
