In this guide, we will discuss how to run a Python script named espota.py. This script is commonly used for uploading firmware to ESP8266 and ESP32 microcontrollers over-the-air (OTA).

Prerequisites

Before running espota.py, ensure you have the following installed on your system:

1. Python: Make sure Python 3.x is installed. You can check your version by running:

   python --version
   

2. Required Libraries: Install the necessary libraries, which may include requests. You can install it using pip:

   pip install requests
   

3. ESP Firmware: You should have the compiled firmware (e.g., .bin file) ready for uploading to your ESP device.

Step-by-Step Guide to Running espota.py

1. Prepare Your Environment

Make sure your ESP device is connected to the same network as your computer. You will need to know the device's IP address.

2. Locate espota.py

Navigate to the directory where espota.py is located. This could typically be within an Arduino or ESP toolkit folder.

3. Open a Command Line Interface

Open your terminal or command prompt. You can do this by searching for cmd on Windows or Terminal on macOS/Linux.

4. Run the Script

To run the espota.py script, you will use the following command structure:

python espota.py --ip <ESP_IP_ADDRESS> --port <PORT> --auth <USERNAME:PASSWORD> <FIRMWARE_PATH>

Replace the placeholders with appropriate values:

• <ESP_IP_ADDRESS>: The IP address of your ESP device.
• <PORT>: The port number (default is usually 3232).
• <USERNAME:PASSWORD>: If you have set up authentication for OTA, provide the credentials.
• <FIRMWARE_PATH>: The path to the firmware binary file you want to upload.

Example Command

python espota.py --ip 192.168.1.100 --port 3232 --auth admin:password firmware.bin

5. Monitor the Upload Progress

After executing the command, you should see output indicating the progress of the upload. The script will inform you when the upload is complete.

6. Restart Your ESP Device

Once the upload finishes, it might be necessary to restart your ESP device for the new firmware to take effect.

Troubleshooting

If you encounter issues while running the script, consider the following:

• Check Network Connection: Ensure that both your computer and the ESP device are connected to the same network.
• Firewall Settings: Make sure that your firewall settings allow Python to communicate over the network.
• IP Address: Verify that you are using the correct IP address of the ESP device.

Conclusion

Running espota.py is an essential process for developers working with ESP8266 and ESP32 microcontrollers, enabling efficient firmware updates over the air. By following the steps outlined above, you can seamlessly upload your firmware and keep your devices up to date.
