CC3200-LAUNCHXL: Sock event handler: [SOCK EVENT] - Unexpected Event [20x] , during HTTPS GET

Hi Jan

Thank You for the reply.

The issue is very similar.

the error is 2

from socket.h (C:\ti\tirtos_cc32xx_2_16_01_14\products\tidrivers_cc32xx_2_16_01_13\packages\ti\mw\wifi\cc3x00\simplelink\include)

/* possible types when receiving SL_SOCKET_ASYNC_EVENT*/
#define SSL_ACCEPT (1) /* accept failed due to ssl issue ( tcp pass) */
#define RX_FRAGMENTATION_TOO_BIG (2) /* connection less mode, rx packet fragmentation > 16K, packet is being released */
#define OTHER_SIDE_CLOSE_SSL_DATA_NOT_ENCRYPTED (3) /* remote side down from secure to unsecure */

I dint understand how it is related to timer.

I am using tirtos, and not non os. The thread is of following format

void connect_to_cloud
{
	while(1)
	{
		if(cli handle=NULL)
		{
			CONNECT TO CLOUD();
		}
		Task_sleep(1000);
	}
}

void get_or post_to_cloud
{
	while(1)
	{
		if(cli handle!=NULL)
		{
			ret=GET FROM CLOUD();
			If(ret=failure)
			{
				DELETE CLI HANDLE
			}
		}
		Task_sleep(5000);                //5 SECONDS
	}
}

How can i avoid the error

If the error is from the cloud server- what causes it?

Thanks a lot

Hi av,

This issue is not similar, it is same actually. Root of issue is not connected with timer. It is related with not proper socket communication inside your code with your cloud server. Your server probably not receive proper data and from this reason is SSL communication closed. You should look to communication between CC3200 and your server by the Wireshark network sniffer to be able determine what is going on.

BTW ... what version of SDK and ServicePack do yo use?

Update: Your issue is definitely not RX_FRAGMENTATION_TOO_BIG. Your issue is OTHER_SIDE_CLOSE_SSL_DATA_NOT_ENCRYPTED. It looks that you use SDK version 1.1.0. This SDK is very old. My recommendation is not use this old SDK and move to latest 1.3.0.

Hi Jan

sdk version is CC3200SDK_1.2.0

tirtos version is tirtos_cc32xx_2_16_01_14

The socket.h file is from tirtos folder

It is related with not proper socket communication inside your code with your cloud server.

i will look into this, and get back

Thanks a lot

Hi av,

And what ServicePack version?

BTW ... inside SDK 1.2 is this code:

/* possible types when receiving SL_SOCKET_ASYNC_EVENT*/
#define SSL_ACCEPT                                (0) /* accept failed due to ssl issue ( tcp pass) */
#define RX_FRAGMENTATION_TOO_BIG                  (1) /* connection less mode, rx packet fragmentation > 16K, packet is being released */
#define OTHER_SIDE_CLOSE_SSL_DATA_NOT_ENCRYPTED   (2) /* remote side down from secure to unsecure */

... inside SDK 1.1 is this:

/* possible types when receiving SL_SOCKET_ASYNC_EVENT*/
#define SSL_ACCEPT                                (1) /* accept failed due to ssl issue ( tcp pass) */
#define RX_FRAGMENTATION_TOO_BIG                  (2) /* connection less mode, rx packet fragmentation > 16K, packet is being released */
#define OTHER_SIDE_CLOSE_SSL_DATA_NOT_ENCRYPTED   (3) /* remote side down from secure to unsecure */

Are you sure what version of SDK do you use and have compiled into your code?

Hi Jan

Since my code is a RTSC project, using TI-RTOS, the source and header files used are from the TIRTOS FOLDER (not the SDK folder). This is the location of the file: (C:\ti\tirtos_cc32xx_2_16_01_14\products\tidrivers_cc32xx_2_16_01_13\packages\ti\mw\wifi\cc3x00\simplelink\include).

Service pack version: CC3100_CC3200_ServicePack_1.0.1.6-2.7.0.0

Thanks
