Currently, several example dependencies rely on the fact that all registered components are added to the build, along with components specified in common requirements. This results in longer build times because even unused components must be built. Switch all examples to use idf_minimal_build to compile only the components actually required by the example.

Device Provisioning Protocol (Enrollee) Example
This example shows how to configure ESP devices as an enrollee using Device Provisioning Protocol(DPP) also known as Wi-Fi Easy Connect.
DPP provides a simple and secure way to onboard ESP devices to a network. We now support DPP in Responder-Enrollee mode with AKM types PSK and DPP.
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 -
- Compile and flash the example on ESP device, a QR code will appear on your console.
- Connect your phone to the network, say named "Example-AP".
- Now go to Settings->WiFi & Internet->Wi-Fi->Example-AP->Advanced->Add Device.
- Scan QR Code using the scanner, which will make ESP device 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 different Terminal program. See below QR Code for checking beforehand.
Example output
Here is an example of the console output.
