CC3100MOD: Software interface of STM32F1 with Wifi CC3100 module(simple link driver)

Hi Srigandeswaran S,

_SlCommandHeader_t is defined in protocol.h, which is in the cc3100-sdk/simplelink/source folder. Be sure your project has this include path.

Best regards,

Sarah

Hi sarah,
          I have checked this thing the protocol.h file is mentioned in the correct path of my project, but the same error exists.

Hi Srigandeswaran S,

Which file do you see the error originate from?

Best regards,

Sarah

Hi sarah,
          The error originate from driver.h file.

Hi Srigandeswaran S,

Do you include SimpleLink headers in your application source code? You should only be using #include "simplelink.h" in your application. The only place you should see #include "driver.h" is in the files in the cc3100-sdk/simplelink/source folder.

Best regards,

Sarah

Hi sarah,
          I have included all these below headers 

#include "wlan.h"
#include "driver.h"
#include "user.h"
#include "simplelink.h"
#include "device.h"

in my main.c file, because If I need to use any one of the WIFI related API means these header files are required.

I could not get you regarding driver.h file what you are saying ,because the driver.h file is already present in the mentioned path only.

Srigandeswaran S

Hi sarah,
         If I remove this header file

#include "driver.h"

from main.c file and if I try to include the WLAN related API like sl_Start(0,0,0) in main.c file means,Iam getting huge number of undefined reference error related to driver.c file and device.c file

Hi Srigandeswaran S,

Did you add the source files from the cc3100-sdk/simplelink/source folder into your project? Or are you linking a pre-built library like simplelink.a?

Best regards,

Sarah

Hi sarah,
         Iam adding the source files from cc3100 SDK only.

Hi Srigandeswaran S,

Can you get a screenshot of the files you have added into your project workspace?

Best regards,

Sarah

Hi sarah,

   These are the Snapshots

Hi Srigandeswaran S,

Can you show the include and linked file paths in your project properties?

The quickest thing you can try is to put "#include protocol.h" above "#include driver.h". But it's possible that may lead to other errors because something else is not linked correctly in your project, since you shouldn't need either of those in your main.c.

Best regards,

Sarah

Hi sarah,
       Files are added and compiled successfully,now facing the problem in the sl_wlansetmode API which is responsible for setting the mode of WLAN ,tried in all three modes like
ROLE_STA ,ROLE_AP which returns -100 always tending to not send the AP mode, The below snippet which is implemented in the code.


      _i32 retVal=0; _i32  mode = 0;

      mode = sl_WlanSetMode(ROLE_STA);

      
      /*HAL_GPIO_WritePin(GPIOE, GPIO_PIN_2, GPIO_PIN_RESET); //WIFI_reset_pin
           HAL_Delay(1000);
           HAL_GPIO_WritePin(GPIOE, GPIO_PIN_2, GPIO_PIN_SET);
           g_Status=0;*/

      mode = sl_Start(0, 0, 0);
      if(mode<0)
      {
          CLI_Write("Error opening interface to device\n");
      }


      mode = sl_WlanSetMode(ROLE_AP);

Hi Srigandeswaran S,

Is the network processor on? You have to create the sl_Task thread and call sl_Start before any other sl_* APIs.

Best regards,

Sarah

Hi sarah,
       yes the Network processor is ON and after using the sl_Task() thread also the error condition exists still  sl_Start(0, 0, 0) returns 1 and sl_WlanSetMode(ROLE_AP) returns -100

Could you please share your mail id for the detailed conversations about the errors facing in my code and also the available time in chat for the conversations of solving these wifi errors 

Regards,
Srigandeswaran S

Hi Srigandeswaran S,

In the code snippet you posted previously, you are calling sl_WlanSetMode before and after sl_Start. Be sure you are only calling it after sl_Start.

Error -100 is SL_API_ABORTED, which means the host driver detected an error. That could also mean there is an issue in your porting layer, or that you do not have a servicepack flashed to the CC3100MOD.

Best regards,

Sarah

Hi sarah,
      For testing purpose,I was using the Sl_Wlansetmode before Sl_start ,i Will check for the service package is flashed or not.

Regards,
Srigandeswaran S

Hi Srigandeswaran S,

Any sl_* command will fail with -100 if called before sl_Start. The sl_Start command is what enables the network processor.

Best regards,

Sarah

Hi sarah,
      Yes Sl_start should be called always first,how to check whether the service package is flashed or not?or whether it comes with the chip.

Regards,
Srigandeswaran S

Hi Srigandeswaran S,

The devices do not come pre-loaded with a servicepack. That is required during production. You can find the current NWP version by using sl_DevGet(). See the Host Driver API guide in cc3100-sdk/docs/simplelink_api.programmers_guide.html for an example.
