ESP-IDF Blufi Example
This demo shows how to use the Blufi to configurate the Wi-Fi connection to AP.
The BluFi for ESP32 is a Wi-Fi network configuration function via Bluetooth channel. It provides a secure protocol to pass Wi-Fi configuration and credentials to the ESP32.
How to Use Example
Before project configuration and build, be sure to set the correct chip target using:
idf.py set-target <chip_name>
To test this demo, you need to prepare a mobile phone with blufi application installed. You can download the blufi application from Android version and iOS version.
Blufi is completely open source, here is the download link:
- Blufi source code
- BluFi protocol
- iOS source code
- Android source code
- Bluetooth Network User Guide CN
Hardware Required
- A development board with ESP32/ESP32-C3 SoC (e.g., ESP32-DevKitC, ESP-WROVER-KIT, etc.)
- A USB cable for Power supply and programming
See Development Boards for more information about it.
Build and Flash
Run idf.py -p PORT flash monitor to build, flash and monitor the project.
(To exit the serial monitor, type Ctrl-].)
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
