Hello there,
I am now writing a program to connect to wap gateway of fetnet01 operator but cannot send out mms data successful. here are the detail handshaking process: <wap gw ip>: 210.241.199.199, <port>: 9201
[step 1]:
send-> invoke 'Connect' pdu
0a 00 03 12 01 10 0a 3c 04 80 8f f8 00 04 81 8f f8 00 a9 50 65 6e 50 6f 77 65 72 20 53 4d 53 2f 4d 4d 53 20 45 6e 67 69 6e 65 00 80 83 80 61 70 70 6c 69 63 61 74 69 6f 6e 2f 76 6e 64 2e 77 61 70 2e 6d 6d 73 2d 6d 65 73 73 61 67 65 00
receive-> 'Redirect' pdu
12 80 03 03 40 C4 00 C0 32 D2 F1 C7 C8

[step 2]:
send-> invoke 'Connect' pdu again
the data in [step 1] to newer addr:210.241.199.200, port: 49202
receive-> 'ConnectReply' pdu
12 80 03 02 C6 F8 F1 26 0A 74 04 80 8F F8 00 04 81 8F F8 00 78 2D 75 70 2D 70 72 6F 78 79 2D 62 6F 6F 6B 6D 61 72 6B 00 68 74 74 70 3A 2F 2F 6D 79 68 6F 6D 65 70 61 67 65 2F 6D 61 72 6B 00 78 2D 75 70 2D 70 72 6F 78 79 2D 75 70 6C 69 6E 6B 2D 76 65 72 73 69 6F 6E 00 35 2E 31 2E 32 2E 36 00 78 2D 75 70 2D 70 72 6F 78 79 2D 68 6F 6D 65 2D 70 61 67 65 00 68 74 74 70 3A 2F 2F 6D 79 68 6F 6D 65 70 61 67 65 00

[step 3]:
send-> 'Ack' pdu
18 00 03

[step 4]:
send-> invoke 'Post' pdu header with mms data(i.e.13769 bytes total)
0A 00 04 12 60 0A 43 68 74 74 70 3A 2F 2F 6D 6D 73 61 70 70 6C 69 63 61 74 69 6F 6E 2F 76 6E 64 2E 77 61 70 2E 6D 6D 73 2D 6D 65 73 73 61 67 65 00 80 61 70 70 6C 69 63 61 74 69 6F 6E 2F 76 6E 64 2E 77 61 70 2E 6D 6D 73 2D 6D 65 73 73 61 67 65 00 88 80 ...(append mms data)
receive-> 'Redirect' pdu
13 80 03 03 40 C4 00 C0 32 D2 F1 C7 C8

I expect to receive 'reply' pdu from gw !
I don't understand why will cause the situation ?
what the actions should I take next step ???
very appreciated for any hints !!!
thanks
julio
