Device Provisioning Protocol (Enrollee) Example

This example shows how to configure ESP32 as an enrollee using Device Provisioning Protocol(DPP) also known as Wi-Fi Easy Connect.

DPP provides a simple and secure way to onboard ESP32 to a network. We now support Responder-Enrollee mode of DPP with PSK mode of authentication.

You need a Wi-Fi Easy Connect with Initiator mode capable device to make use of this example. Some Android 10+ devices have this capability. (Vendor specific)

To run the example with an Android 10+ device follow below steps -

1. Compile and flash the example on ESP32, a QR code will appear on your console.
2. Connect your phone to the network, say named "Example-AP".
3. Now go to Settings->WiFi & Internet->Wi-Fi->Example-AP->Advanced->Add Device.
4. Scan QR Code using the scanner, which will make ESP32 connect to Example-AP.

Optional configuration available

Note:

• QR Code should be displayed as dark on a white/light background to work properly.
• If displayed QR Code had line gaps, try switching to a new font or a diiferent Terminal program. See below QR Code for for checking beforehand.

Example output

Here is an example of the console output.
