CC3220SF-LAUNCHXL: Simplelink WiFi Provisioning Android Source 2.2.17

Hi Guys,

I am using a CC3220SF-LAUNCHXL board running the OOB app.

If I use the SimpleLink Starter Pro Android app I am able to do the provisioning successfully.

I have downloaded the Android source code ( Simplelink WiFi Provisioning Android Source 2.2.17 ) but I could not make it run in the latest Android Studio 2.33

So I started reading the source code to figure out how to use the smartconfiglib2.jar.

I have created a test android app that use the smartconfiglib2.jar as dependency. ( Code below)

When ReadWiFiCredentials is executed the wifi SSID and wifi password are read from user inputs on editboxes.

Then the app check if Wifi is available and get the ip address of the gateway (Wifi router ip).

Then the app try to create an instance of SmartConfig but I always get :

SocketExcention and Log.e(TAG, "Failed to create instance of smart config") 

The phone which runs the app in connected to the WiFi Router.

I think I am missing something before I create an instance of SmartConfig but I could not figure out what.

Any help will be higly appreciated.

Thanks
