Additionally, it’s easy to install, so you shouldn’t have problems with the installation process.Note: we’ve also experimented with uPyCraft IDE and it worked fine for us. It even comes installed by default with Raspbian OS for Raspberry Pi. In our case, the machine running the SMTP server is the smtp.gmail.com and we want our client application (running on our laptop) to be able to communicate with that server.It allows you to program your ESP32 and ESP8266 boards with MicroPython, and it is compatible with Windows, Mac OS X, and Linux. In a regular network, all devices communicate normally to the gateway and then to the internet as shown in the following image: Now the attacker needs to send ARP responses to both hosts: Sending ARP response to the gateway saying that 'I have the victim's IP address'.The smtplib python module defines an SMTP client object that can be used to send email to any machine running an SMTP server. I did where python3.9 because I knew I wanted that version to be used.So, in this tutorial, we will write a Python script to do just that. On a mac, you can find this by doing where python3 in the terminal.Flashing MicroPython Firmware with esptool.py on ESP32 and ESP8266In this guide, we provide instructions to install Thonny IDE in different operating systems, read the section that fits your needs:Tip: Thonny IDE comes installed by default on Raspbian OS that is used with the Raspberry Pi board. That’s the first thing you need to do to start programming your boards with MicroPython: flash/upload the firmware.Follow the next tutorial to flash MicroPython firmware on your board using esptool.py: Install uPyCraft IDE – Linux (Ubuntu 16.04) InstructionsDownloading and Flashing MicroPython FirmwareUnlike other boards, MicroPython isn’t flashed onto the ESP32 or ESP8266 by default. Install uPyCraft IDE – Mac OS X Instructions Install uPyCraft IDE – Windows PC Instructions So, here we provide another great IDE to program your ESP32/ESP8266 boards using MicroPython.If you want to use uPyCraft IDE instead, follow one of the installation tutorials below:
![]() ![]() You just need to click “Next”.5. Follow the installation wizard to complete the installation process. Download the version for Windows and wait a few seconds while it downloads.4. Python Script To Send Generic Email Software To RunFollow these next instructions to enable any downloaded software to run in your Mac.1. For security reasons, Mac OS X blocks unknown apps to run on your computer. A window as shown in the following figure should open.Since Thonny IDE is open source and downloaded from the Internet, it’s not a verified app in the App Store. Chroma key sony vegas download freeDownload the version for Mac OS X and wait a few seconds while it downloads.4. Finally, select the option “Allow apps downloaded from: Anywhere“.To install Thonny on Mac OS X, follow the next instructions:2. Type your username/password and click the “ Unlock” button.5. A window as shown in the following figure should open.To install Thonny on your Linux computer, it depends on your Linux distribution and version, follow the next instructions for your system. After the installation is completed, open Thonny IDE. Thonny IDE is now installed and you can double-click to open it:6. Type the command help() in the Shell and see if it responds back.If it responded back, everything is working fine. Thonny IDE should now be connected to your board and you should see the prompt on the Shell.5. Otherwise, select the specific port for the board you’re using.4. Then, select your device serial port (recommended).You can also select the “ Try to detect automatically” option, but only if you just have one board connected to your computer at a time. Ubuntu (after running that command, you’ll need to press Enter again to install the software):Bash Options and select the Interpreter tab.2. Choose MicroPython on a generic device.3. You can open more than one file, and the Editor will open a new tab for each file. The Editor section is where you write your code and edit your. There are two different sections: the Editor and the MicroPython Shell/Terminal: ESP32/ESP8266 flashed with MicroPython firmwareOpen Thonny IDE. Running Your First ScriptTo get you familiar with the process of writing a file and executing code on your ESP32/ESP8266 boards, we’ll upload a new script that simply blinks the on-board LED of your ESP32 or ESP8266. It lists all available variables in your program and their corresponding values. Go to View and you can select several tabs that provide more information.Something that could be very useful is the Variables tab. The terminal also provides information about the state of an executing program, shows errors related with upload, syntax errors, prints messages, etc…You can also customize Thonny IDE to show other useful tabs. Copy the following code to the main.py file: from machine import PinGo to Device and select Upload current script as main script.It should write the following on the Shell.Note: uploading the code as main script will save the current file with the name main.py on the ESP, even if you have saved it in your computer with a different name. The Editor should now have a tab called main.py.3. Simply, click the save icon and name the file main.py.2. Save that file as main.py. When you open Thonny IDE for the first time, the Editor shows an untitled file. The file should be saved on the ESP with the name “umqttsimple.py” Go to Device > Upload current script with current name Save it in your computer with the exact name that you want, for example “umqttsimple.py” Uploading Files/LibrariesTo upload a file with a unique name to your ESP using Thonny IDE, follow these next steps: For example: %cat / main.pyAlternatively, to show the boot.py and main.py scripts, you can also go to Device and select one of the options: Show device’s main script or Show device’s boot script. List Files Saved on ESP32/ESP8266To list all files saved on the ESP board, type in the Shell: %lsdeviceTo show the file content, use %cat / followed by the file path. (On some occasions it helps to wait before trying again.)Or: = RESTART =Make sure your device has suitable firmware and is not in bootloader mode!Unplug, and plug back your ESP board. In case it doesn’t work for you, read these next common errors and discover how to solve them.Error #1: You get one of the following messages: = RESTART =Error: could not open port 'COM4': FileNotFoundError(2, 'The system cannot find the file specified.', None, 2)Check the configuration, select Run → Stop/Restart or press Ctrl+F2 to try again. Or pressing the Thonny IDE “ Stop/Restart backend” button and repeating your desired action. Usually restarting your ESP with the on-board EN/RST button fixes your problem. So, in order to remove/delete all files completely from your ESP, you need to re-flash it with MicroPython firmware.Note: you can upload a blank script to the ESP board to remove/delete code.We’ve discovered some common problems and error messages that occur with Thonny IDE. You can see the file content using the %cat /umqttsimple.py command:At the moment, Thonny IDE doesn’t have a command to remove a file from the ESP. You should now be able to upload a new script or re-run new code. Then, click the “ Stop/Restart backend” button to establish a serial communication.
