I can send MM to a mobile device with wsp-connect and wsp-post, and client can receive the MM successfully, but when I disconnect, get abort response with 0xE0,why?
GW=>Client wsp-connectreply: x02,0x83,0x92,0x44,0x00,0x15,0x45,0x6e,0x63,0x6f,0x64,0x69,0x6e,0x67,0x2d,0x76,0 x65,0x72,0x73,0x69,0x6f,0x6e,0x00,0x31,0x2e,0x32,0x00
Client=>GW wsp-disconect

Excuseme, you succeed to send MMS!!
I do not succeed.
what exactly I must send to the gateway for connection?
I must make a connection oriented logon or
a connectionless logon?
you could make an example of wsp connect byte
I am in series difficulty Thanks

Anonymous,

It is difficult to answer because the connect-reply and disconnect PDUs that you include only have the WSP part of the PDU, not the WTP header. Yet the WTP abort is a WTP PDU ... so I can't match up transaction ids to understand the flow.

My guess would be that you are not sending a WTP ACK for the connect reply ... so when you send the disconnect, the gateway aborts the connect reply transaction that you never ACK'd.
