CCS/MSP432P401R: CC3120

Hi Michael it would be great to get some help on this project. Is there any other way I can communicate with you regarding this project. Any kind of help would be amazing.

Hi,

I would be happy to help out on this thread. Please let me know what specific issues you are having with getting UDP functionality working on the CC3120 and I can assist you in debugging and working through your problems.

Regards,

Michael

Hello Michael, I am working with Ayush on this project.

I am having a problem with the use of the sl_Socket function inside UDPServer. It is giving the error code -99 - Cannot assign requested address.

The code compiles correctly up until this socket creation. Could this be an issue in using ParseRecvCmd incorrectly? I am seeing all the initially intended param assignments happening in my UART terminal which makes me think not.

I know the Msg Structure is returning the .sd value of 0 upon the sl_Socket call. The value is 17 before VERIFY_RET_OK is called. Even with this one call commented out it still  turns to zero for some unexplained reason.

Thank you in advance. Any direction at all in debugging this problem is appreciated.

UART Terminal right before the error return.

Expressions directly before sl_Socket is called

Expressions inside sl_Socket just before returning.

_i16 sl_Socket(_i16 Domain,
               _i16 Type,
               _i16 Protocol)
{
    _SlSockSocketMsg_u Msg;

    Msg.Cmd.Domain = (_u8)Domain;
    Msg.Cmd.Type = (_u8)Type;
    Msg.Cmd.Protocol = (_u8)Protocol;

    /* verify that this api is allowed. if not allowed then
       ignore the API execution and return immediately with an error */
    VERIFY_API_ALLOWED(SL_OPCODE_SILO_SOCKET);

    VERIFY_RET_OK(_SlDrvCmdOp((_SlCmdCtrl_t *)&_SlSockSocketCmdCtrl, &Msg,
                              NULL));

    if(Msg.Rsp.StatusOrLen < 0)
    {
        return (Msg.Rsp.StatusOrLen);
    }
    else
    {
        return((_i16)((_u8)Msg.Rsp.Sd));
    }
}

Hi,

What is your exact code you use for creating the UDP socket, is it based off of the network_terminal example? If you could please provide me the code you are currently using, I can  run it on my end, reproduce your error, and better understand the issue you are seeing.

I would appreciate it if you could insert the code using the syntax highligher.

Thanks,

Michael
