The application performs the following steps:

  • Initializes the device networking layers.
  • Connect to Access Point with SSID "cc3200demo" and Security as "Open"
  • Wait for the Connection to the AP
  • Once AP connection is done, It Configures the XMPP Server and Login Information
  • It then Connects to Configured XMPP Server ( followed by authentication using Base64 Encrypted Login Credential
  • Once Authentication is Successful, It waits for a chat message from another Client
  • Once it receives the Chat Message, It replies back with the Same message

NoteNote: Use your own email-id (CLIENT_USER_NAME) & password(CLIENT_PASSWORD) in source code (main.c) and build the project before running the application.
This example can be used either on TI-RTOS or FreeRTOS.

For the application to work with TI-RTOS, ti_rtos_config project needs to be imported into the application workspace. These projects can be found in CC3200-SDK under ti_rtos folder. Please follow this link for CC3200 TI-RTOS usage CC3200 TI-RTOS
