Wi-Fi Provisioning over BLE

Overview

TI developed a demo to demonstrate how the BLE functionality of the CC33xx 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 CC33xx 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 CC33xx BLE peripheral and passes the Wi-Fi credentials.
