Hello. I'm writing a program, which sends MMS messages through a gsm modem. I have already implemented WTP/WSP stack, and it does work fine with wap gw of tele2 operator. I can send MMS messages through operators MMSC without any problem, however, when I try to send WSP Connect to another operator's GW (omnitel) I always receive abort message with E0 code, which is Protocol error I believe. Here'is the communication of my program with gw: WDP --> 0A 28 D2 12 01 10 24 0A 04 80 85 BF 10 04 81 85 BF 10 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 WDP <--21 A8 D2 E0 Now here is the session of communication if I send Connect without headers but with capability negotiation: Sending 0 WDP --> 0A 28 D2 12 01 10 00 0A 04 80 85 BF 10 04 81 85 BF 10 WDP <-- 12 A8 D2 02 B1 BD 3D 00 15 45 6E 63 6F 64 69 6E 67 .........Encodin 2D 76 65 72 73 69 6F 6E 00 31 2E 32 00 [WTP] RESULT RECEIVED!

Why? E6 means Maximum Receive Unit exceeded. But when I establish a session I send to the gw, that I will not send a packet bigger than 90000b. This MMS is about 2.5kb. I can't understand, where is the problem? Maybe the problem in WSP Connect packet? Thank you. | |||

My god! I found the problem! How stupid I am! I swapped Capability Length byte with Header length byte! Sorry for this silly question/topic! | |||

It cause by stupid WAP gateway. Gateway use SDU_SIZE as Message_size, Gateway Server_SDU_Size is larger than 300K, So if your Server SDU SIZE is smaller than what your want to sent size, Abort will be receive. I don't know how to fix problem except that set Server_SDU_Size to 350K. | |||
