Wi-Fi Provisioning over BLE Example Summary

TI developed a demo to demonstrate how the BLE functionality of the CC35xx can be used to provision it to a Wi-Fi AP of the user’s choice. This works by passing the Wi-Fi AP credentials to the CC35xx via BLE using a phone or a similar device.

The provisioning sequence is shown below where a user scans for BLE devices, connects to the CC35xx BLE peripheral and passes the Wi-Fi credentials.

Prerequisites

Install the ‘SimpleLink Connect’ application on your phone or device

Example Usage

Flash the Ble Wifi Provisioning example as explained in the platforms getting started guide
Open a serial port session (e.g. ‘HyperTerminal’,‘puTTY’, ‘Tera Term’ etc.) to the appropriate COM port -
listed as ‘User UART’. The COM port can be determined via Device Manager in Windows or via ls /dev/tty* in Linux.

The connection should have the following connection settings:

    Baud-rate:    115200
    Data bits:         8
    Stop bits:         1
    Parity:         None
    Flow Control:   None

Once the application has complete it’s initialization and the network processor is up,
the application banner would be displayed, showing version details:
```
***********************************************************************
********************   BLE WiFi Provisioning   ************************
********************   Version x.x.x.x         ************************
***********************************************************************
```
At this point, the application will wait for a BLE connection from the mobile application. Once a BLE connection is made the user can enter the WLAN credentials (SSID and Password) to be used for the WLAN connection.

Mobile Application Usage

Open the application and enable BluetoothLE Scan
Find the device that advertises as TI CC3xxx and connect to it
Open the device services and enter to the “Wi-Fi Provisioning Over BLE” service
Enter SSID and select the Security type in the drop list (Open/WPA2). In case WPA2 was selected, enter the Password
Click on Connect and wait for the status to be updated
