Hi, I am trying to send a large iMelody file over EMS. However I am having trouble adding the ODI header for some reason. I have already been able to split the melody into several messages and send it with the UPI header. Problem came up when I added the ODI, the phone receives nothing (in fact it gets blocked for quite a while and is unable to receive any sort of message). The melody I am sending is:

BEGIN:IMELODY
VERSION:1.2
FORMAT:CLASS1.0
BEAT:125
MELODY:*5f3r4*5f4*5c4r4*5f1r3*4#g3*4a2*5c3*4f2r3*4a4*5c4*5f3*5c3*5g3*5f2r2r3*5d3 r4*5d4*5c4*4a3r4*5c2r2
END:IMELODY

And the final UDH's are:

8b UDH length
17020001 ODI, all IE, forward lock
130102 UPI, 2 parts
0C7d00 EMS imelody, length 7dh, offset 0
424547494e3a494d454c4f44590d0a56455253494f4e3a312e320d0a464f524d41543a434c415353 312e300d0a424541543a3132350d0a4d454c4f44593a2a35663372342a3566342a35633472342a35 663172332a342367332a3461322a3563332a34663272332a3461342a350d0a454e443a494d454c4f 44590d0a

7e UDH length

0C7700 EMS imelody, length 77h, offset 0
424547494e3a494d454c4f44590d0a56455253494f4e3a312e320d0a464f524d41543a434c415353 312e300d0a424541543a3132350d0a4d454c4f44593a3563332a3567332a356632723272332a3564 3372342a3564342a3563342a34613372342a35633272320d0a454e443a494d454c4f44590d0a

Could anyone point me in the right direction?

Regards

Sorry, it works now ... there is no problem with the UDH's, it was a comm problem with the handset, it wasn't sending the messages at all!
