- Solder the ESP32-S2-MINI-2 module to the RF testing board.
- Connect the RF testing board to the USB-to-Serial board via TXD, RXD, and GND.
- Connect the USB-to-Serial board to the PC.
- Connect the RF testing board to the PC or a power adapter to enable 5 V power supply, via the Micro-USB cable.
- During download, connect IO0 to GND via a jumper. Then, turn ”ON” the testing board.
- Download firmware into flash. For details, see the sections below.
- After download, remove the jumper on IO0 and GND.
- Power up the RF testing board again. The module will switch to working mode. The chip will read programs from flash upon initialization.
2. **Set up Development Environment:**
- Install prerequisites and ESP-IDF as mentioned in the user manual.
- Set up tools using the 'install.sh' script provided by ESP-IDF.
- Set up environment variables using the 'export.sh' script provided by ESP-IDF.
3. **Create Your First Project:**
- Start a project by copying the 'hello_world' project from the examples directory in ESP-IDF to your installation directory.
- Connect your module to the computer and identify the serial port.
- Configure the project using the 'menuconfig' utility.
- Build the project by running 'idf.py build'.
- Flash the binaries onto your module by running 'idf.py -p PORT flash' (replace PORT with your ESP32-S2 board’s serial port name).
- Monitor the application by running 'idf.py -p PORT monitor' to check if it is running correctly.
By following these steps, you can connect your ESP32-S2-MINI-2 WiFi module to your computer and start developing applications for it. For more detailed instructions and troubleshooting, refer to the ESP32-S2-MINI-2 WiFi Module User Manual provided by Espressif.
