CC3100 - error code -100 ?!

Hi Lenio,

Is (-100) returned from the function call itself? I believe this is SL_API_ABORTED which can happen when an expected response is not received from the network processor. It is difficult to try to understand the cause without more context.

Can you give more details around the steps being taken/APIs being used up to this call and whether or not repeating the call results in the same return value?

Thank you,
Ben

Hi Ben,

here is the code snippet along with the comment on where the error is returned - thank you!

if (status == 0)
            {
                status = connect(tmpSkt, (struct sockaddr *)&address, sizeof(address));   <<< -100 is returned by connect() API

                if (status < 0)
                {
                    returnStatus = WIFI_PLATFORM_STATUS_SOCKET_CONNECT_FAILURE;
                    if (tmpSkt >= 0)
                    {
                        if(status == SL_ESEC_ASN_SIG_CONFIRM_E)
                        {
                            returnStatus = WIFI_PLATFORM_STATUS_SOCKET_CERTVALIDATION_FAILURE;
                        }
                        close(tmpSkt);
                    }
                    
                }
                else
                {
                    *skt = tmpSkt;
                }
            }

Hi Lenio,

Thanks for the extra detail!

Can you provide more details about the SimpleLink APIs being used before this section? The "connect()" function seems to be built on top of our APIs. Can you provide more insight into the steps being performed inside? Is this just a wrapper for sl_Connect()?

Thanks,
Ben

Yes, it is just a wrapper:
#define connect sl_Connect

Thank you!

Lenio,

Please provide extra details on what APIs are used before the call to connect().

Thanks,
Ben

Hi Lenio,

The use case looks ok from what I can see. This makes me think that the CC3100 and the host are just getting out of sync, which could be caused by a problem with the host interface itself.

Does this happen every time the code is run?
What type of interface is being used?

Thanks,
Ben

The host microcontroller is a NXP K24. We have provided the SPI interface software compatible with the K24.

When you mention being out of sync, do you have examples of practices to avoid in the code?

Ben,

thanks for the suggestions .We will verify. I will close the thread for now while we are running tests.
