XMPP client continuously recieving message after logout

Other Parts Discussed in Thread: CC3200

Dear All:

    I use the XMPP client example in the CC3200 SDK to connect to my XMPP server (OpenFire). Everything seems fine, but after I leave the CC3200 for some minutes, it will logout from the server. And then, the client continuously shows the last message before logout. I tried to stop the XMPP server but the client is still showing the message.

   Could anybody help the question please?

    Hi Tonny,

    Please share the below information:

    • Did you modify the SDK example or you are using it as it is?
    • Can you also share the service pack version you are using?

    Service pack version should be printed as 

    Build Version x.x.x.x.31.x.x.......

    Regards,

    Ankur

    Hi Ankur,

       Thanks a lot for your reply.

       I haven't changed anything of the XMPP client sample code. But I don't know how to find the version of service pack, would you tell me please?

      However, I found another thing may be the reason for the problem. In the main.c, there're the following code of the function "XmppClient":

    while ( Status < 0)
    {
    MAP_UtilsDelay(10000);
    Status = sl_NetAppXmppRecv(pRemoteJid, REMOTE_USERID_LEN, pRecvMessage, RECV_MSG_LEN );
    }

    // the code is omitted

    Status = sl_NetAppXmppSend(pRemoteJid, strlen((char*)pRemoteJid),pRecvMessage,
    strlen((char*)pRecvMessage) );

    and the function of sl_NetAppXmppRecv shows in the xmpp.c that,

    Status = sl_Recv(g_SockID, g_RecvBuf, BUF_SIZE*2, 0);

    //the code is omitted

    return Status;

    In my option, if the connection is closed by remote server, the return value of both "sl_Recv" and "sl_Send" be 0. Hence, the "Status" in the function "XmppClient" would be always 0 in the case, and because of 0<0 is false, it will continuously toggle the LED and send the message to the server.

    Could you help to check the analysis please?

    Thanks a lot.

    I've finally founded the solution, maybe it can be usefull for other guys that need help. My solution was to configure XmppOption.SecurityMethod = SL_SO_SEC_METHOD_SSLv3_TLSV1_2;
    XmppOption.SecurityCypher = SL_SEC_MASK_SECURE_DEFAULT;
    After this the XMPP SDK example runs flawless.
    Regards.
