ESP32 WiFi Provisioning Manager

Convenient reusable C++ ESP-IDF component that wraps wifi_provisioning component, that enables WiFi provisioning over WiFi. Usage example is shown in main/main.cpp.

For now, it's still optimized only for provisioning over WiFi/SoftAP. The code for provisioning over BLE is there, I haven't tested it yet.

In this example, the sdkconfig.defaults file sets the CONFIG_EVENT_LOOP_PROFILING option. This enables both event loop profiling that will list out all registered events.

How to use example

Hardware Required

Any ESP32 family development board.

Apps Required

Unless you're developing your own app, it's faster to use existing "official" app from Espressif in order to quickly test the provisioning.

Android:
- BLE Provisioning app on Play Store
- SoftAP Provisioning app on Play Store
iOS:
- BLE Provisioning app on app store
- SoftAP Provisioning app on app Store

If you do need to integrate provisioning functionity into your own app, get the library here:

Source code on GitHub: esp-idf-provisioning-android
Source code on GitHub: esp-idf-provisioning-ios

Configure the project

idf.py menuconfig

Build and Flash

idf.py -p PORT flash monitor

(Replace PORT with the name of the serial port.)

(To exit the serial monitor, type Ctrl-].)

See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.

Upon successful provisioning, you'll see this output:

D (30024) WIFIPROV: >> Station connected
D (31594) WIFIPROV: >> Station got IP: 192.168.31.51

As you can see, ESP32 gets the IP address.
