hey developers,

my problem is that Nokia device doesnt recognize
arrived smss as smart messages. Over CIMD2 protocol there were no problems at all, but with this SMPP...
What is a 'right' way to transfer smart messages over this protocol? Now i'm trying to use SUBMIT_SM PDU (just like for text messages, only i set data coding scheme to 4) and at the end of the pdu I attach only two optional parameters - source port and destination port, so the ending of my sms in hexdump looks like: ..."02 0A 00 02 15 81 02 0B 00 02 15 81" (ps the ringtone is only 30bytes, so no segmentation needed for this one)

when such message arrives to nokia, it displays
"1 new message arrived" and when i try to read it, the device says "cant display the message" (i think because of the binary encoding)

any ideas would be greatly appreciated!

thanx 4 considering;)

Maybe the problem is with DCS:

> i set data coding scheme to 4

but for smart message DCS must be 0xF5 (245).
Try this...

thanx:-)

it IS possible to form proper smss suitable to transfer ringtones&stuff over SMPP ;)

final word:

to send an EMS (ringtone/logo/pics...) via SMPP set:

-----------------------------------------------
ESM class = 0x40 (6th bit set - which means User Data Header is present at the beginning of message section)

DCS = 0xF5 ( ;) )

DoNot use any of SMPP supplied optional parameters fields (ie for port numbers, segmentation etc - UDH replaces all needed ones), and other SMPP mandatory fields as for simple text sms.
-----------------------------------------------

uf... these few words sum all last 2days work...
time out...
