Provisioning Application Examples

This primarily consists of a single unified example wifi_prov_mgr

• wifi_prov_mgr Abstracts out most of the complexity of Wi-Fi provisioning and allows easy switching between the SoftAP (using HTTP) and BLE transports. It also demonstrates how applications can register and use additional custom data endpoints.

Provisioning applications are available for various platforms:

• Android:
  • BLE Provisioning app on Play Store.
  • SoftAP Provisioning app on Play Store.
  • Source code on GitHub: esp-idf-provisioning-android.
• iOS:
  • BLE Provisioning app on app store
  • SoftAP Provisioning app on app Store
  • Source code on GitHub: esp-idf-provisioning-ios
• For all other platforms a python based command line tool is provided under "$IDF_PATH/tools/esp_prov"

The Android and iOS provisioning applications allow the user to configure the device manually or by scanning a QR code. QR codes can be generated by any online QR code generator. QR code payload is encoded with a JSON string containing the device name, proof-of-possession key (if used) and transport type (BLE or softAP), for example:

{"ver":"v1","name":"PROV_000318","pop":"a1000318","transport":"softap"}

The more details about QR code format, you can refer to QR Code Scan.

Legacy Examples

The legacy examples require own implementation of provisioning functions and handlers. The Wi-Fi provisioning component abstracts out most of this complexity and provides a simpler interface and so, that is recommended for use. However, if you want to use lower level provisioning and protocomm APIs, you can check the these examples under legacy/ folder:

• softap_prov Provisioning involves Wi-Fi station configuration via an HTTP server running on the device, which is initially configured to be in SoftAP mode. After provisioning, device runs in Wi-Fi station mode only and connects to the AP whose credentials were provided during provisioning.

• ble_prov Provisioning involves Wi-Fi station configuration via BLE service endpoints running on the device initially. After provisioning, BLE is turned off and device runs in Wi-Fi station mode, connecting to the AP whose credentials were provided during provisioning.

• console_prov Provisioning involves Wi-Fi station configuration via UART console. This is intended for debugging protocomm and provisioning related features.

• custom_config Similar to softap_prov examples, but allows for configuration of custom (device-local) information during provisioning. This is intended as an example for implementing custom provisioning schemes.
