Hi Manish,

If you have an HTTP page already working with the HTTP post request handler, then I suggest you use the sl_WlanProfileAdd() API to add the credentials to the CC3220 NWP. See my post here for details:

HI Manish,

Looking at your HTML file, the main change I would make is to set the form encoding as "application/x-www-form-urlencoded". With that set, the SimpleLink NetApp request handler will copy the POSTed form data into netappRequest->requestData.pPayload. From there, you can strcmp() through the data to get the POSTed data. Once you have the data, you can use sl_WlanProfileAdd() to save the profile onto the device.

I verified the above with your config.html and the out_of_box example from the SDK, so I suggest trying your file out in that example if you still run into issues. Some more notes:

Ensure you flash the OOB files at examples/rtos/CC3220SF_LAUNCHXL/demos/out_of_box/uniflash/
Ensure you set the Imagecreator project into 'development' mode after importing
I suggest you use the 'addprofile' command in network terminal to skip the provisioning of the OOB example

Regards,

Michael

Hi Michael,

As you have said ain above post "I verified the above with your config.html and the out_of_box example from the SDK." And you also said this I would make is to set the form encoding as "application/x-www-form-urlencoded". Can you please tell where to set the form encoding as "application/x-www-form-urlencoded" because I don't know anything about HTML. Please assist me show that you can move further to close this thread.
