PRO_CMD_SEND_SHORT_MESSAGE

Question

Hello Guys,
I am trying to send sms from a STK application using PRO_CMD_SEND_SHORT_MESSAGE proactive command. It works well on most handsets, but I noticed that it cannot work on certain handsets like samsung omniaII and SE Xpreia. (Other STK services like receiving sms, displaying text are okay) Do you have an idea about this problem ? Where should I focus on. Same program, same card but different handsets I am really stuck.
Regards

Hi igosneves
First : i noticed that
/ / TP-DA length
tempBuffer[2] = (byte)0x03; // i.e destination address is 3 digits
tempBuffer[5] = (byte)0x00;//so if ur number 740 ,so tempBuffer[5] should be F0
Second:
to send SMS contains large data (theoretical > 140 bytes ) , u must divide original SMS into segments each one is limited to 140 bytes with the concatenated messages options.
i.e
// TP-MTI +
TPDU[0]=tempBuffer[0] =(byte)0x41 ;// 0 1 0 0 0 0 0 1 ,i.e SMS-SUBMIT +
|
user data header indicator i.e there are optional features in this SMS
u must add TLV describing concatenated short messages , before user data
Tag for concatenated short messages = 0x00
length = 0x03
Referance Number = consatnt byte (0x00 to FF), all segments of sharing this SMS must have the same value
Total number of seg. in entire msg. = consatnt byte (0x01 to FF), all segments of sharing this SMS must have the same value
Index of this Segment = 1 to N(Number of segments) ,segment number u must adjust this byte for every segment
i.e
tempBuffer[8] = (byte)tempMessageSize+(byte)0x05 ; // 5 bytes of concatenated short msg.
tempBuffer[9] = (byte)0x00;
tempBuffer[10] = (byte)0x03;
tempBuffer[11] = (byte)0x00;
tempBuffer[12] = (byte)NumberOfSegments;
tempBuffer[13] = (byte)IndexOfSegment;
