This example demonstrates how to pass the AP credentials to WINC1500 device via BLE of WBZ451.
This application shows how a user can use the WBZ451's BLE to send the target AP credentials to a WINC1500 device. After pairing with the smart phone, the user can use the "Microchip Bluetooth Data" mobile application to send the AP credentials to the WINC1500 via BLE Custom service created in WBZ451 device.

Because Microchip regularly update tools, occasionally issue(s) could be discovered while using the newer versions of the tools. If the project doesn’t seem to work and version incompatibility is suspected, It is recommended to double-check and use the same versions that the project was tested with.

The below figure shows configurations used in custom service component.
- On startup, WBZ451 will Advertize with local name wbz451_winc1500_wiifiProv
- Open the Tera Term terminal application on your PC. The WBZ451 will show the welcome message in Tera Term after intialization as shown below.
- Open MBD app in iPhone, touch on BLE Provisioning and touch on WINC3400.
- The MBD app will scan for ble advertising device and will display the device wbz451_winc1500_wifiProv as shown below.
- Select wbz451_winc1500_wiifiProv to connect with wbz451_winc1500_wiifiProv device.
- The console log in tera term will display the Bluetooth pairing pass code as shown below.
- In MBD App, Enter the pairing pass code as shown below.
- When pairing is sucessfully completed, the console log in Tera Tem will show a success message as shown below.
- Enter the SSID, Passphrase and select Wi-Fi Authentication Type. (In this example, the iPhone only supports "Open" and "WPA". On the Android phone, only "Open" is supported.)
- Press provision button. Now the MBD app will send the Wi-Fi Provisionig credentials to WBZ451 device. WBZ451 will disconnect BLE connections then intialize WINC1500 and connect to the AP.
- Once connected, the device's IP address will be displayed in the Tera Term console log as shown below.
