LAUNCHXL-CC3235SF: WiFi Direct code

Part Number: LAUNCHXL-CC3235SF
Other Parts Discussed in Thread: CC3235SF

Tool/software:

Hi,

My customer is trying evaluate WiFi direct feature on Launchpad.
It seems there is no example project in SDK, so they modified "empty_CC3235SF_LAUNCHXL_freertos_tilang" and added WiFi direct feature.
They refers to below document page 63 and later.
https://www.ti.com/lit/ug/swru455m/swru455m.pdf

*  ======== empty.c => wifiDirect.c ========
*/

/* For usleep() */
//#include <unistd.h>
//#include <stdint.h>
//#include <stddef.h>

/* Driver Header files */
//#include <ti/drivers/GPIO.h>
// #include <ti/drivers/I2C.h>
#include <ti/drivers/SPI.h>
// #include <ti/drivers/Watchdog.h>
#include <ti/drivers/net/wifi/simplelink.h>
#include <ti/drivers/net/wifi/slnetifwifi.h>
#include <ti/display/Display.h>

/* Driver configuration */
#include "ti_drivers_config.h"
#include "pthread.h"
#include "semaphore.h"

#define APPLICATION_VERSION "1.0.0"
#define DEVICE_NAME "Simple_WiFi_Direct"
#define DEVICE_TYPE "WiFi_Direct_Device"

But they got below build errors. What causes these unsolved symbol errors?

Thanks and regards,

Hi Koichiro,

This is wrong approach.Your customer should not start project from scratch. Recommanded way is to use one of SDK examples and modify that code. If you start project from from scratch, you will fall into same rabbit hole as your customer with many dependences errors. That state may to be hard to solve even for experience user with this WiFi platform.

Hello Koichiro,

Exactly what Jan said. It seems your customer is running into dependency issues and not including the proper libraries and includes necessary for the Network Calls.

Best,

Hi Jan, Rogelio,

Thanks for your replies.
According to the customer "empty_CC3235SF_LAUNCHXL_freertos_tilang" is one of SDK examples.
But it does not work.

Anyway he will try to start from different project.
What is your recommended project for WiFi Direct (Group Owner mode) ?

Thanks and regards,
Koichiro Tashiro

Hi Koichiro,

I would recommend the customer starts off playing with the Network terminal example particularly the p2p commands

https://dev.ti.com/tirex/explore/node?a=IOGqZri__3.80.13.03&node=A__AO8xUCN6WBxT6flmjYWsUA__com.ti.SIMPLELINK_CC32XX_SDK__fc2e6sr__LATEST

More information on wifi direct could be found in the Network Processors guide.

Section 4.5

Hi Rogelio,

Thanks for your reply.
The customer used that example and confirmed the p2p commands worked.
He will continue more verification based on that project at his side, but this item is closed for now.

Thanks and regards,
Koichiro Tashiro
