BasicOTA: Program ESP32 (or ESP8266) via ArduinoOTA, on Windows 10/Arduino IDE

One of the very useful feature of ESP32/ESP8266 is OTA (Over-The-Air) programming; such that you can update the firmware without physically connect to the device.

With ESP32/ESP8266 core for Arduino installed to your Arduino IDE, you can find ArduinoOTA examples of BasicaOTA and OTAWebUpdater under Examples for ESP32 Dev Module.

This post show trying BasicOTA examples on ESP32-DevKitC using Arduino IDE running on Windows 10, and fix the problem I faced:  Network Ports no shown and No response from device.

Basically, the default DevKitC firmware have no OTA function. So you have to flash the first firmware with OTA function using serial port (USB). After then, you can update your firmware via OTA without physical connected serial port. Both the computer used to update the firmware and the ESP devices to be updated have to be in the same network.

The ESP device I used in this example is ESP32-DevKitC with ESP32-WROOM-32 module. It should be a relatively old and original version.

Somebody (include me) reported there are no Network Ports shown up. 

Somebody suggested to install Python, somebody suggested to reboot router, or install Bonjour... All of them not work for me. In order to eliminate the problem outside my computer, I decide to use Windows 10's Mobile hotspot.

Open BasicOTA example and change ssid and password according to my network setting. Upload the ESP32 device via serial port (USB, or COM5 in this example).

Turn on Windows 10's Mobile hotspot with matched ssid/password.

Now the Network ports shown, with attached device (the programmed ESP32 with OTA function) and its assigned ip.

Once Network port selected, the Arduino IDE's Serial Monitor not work on network. So I run Putty to monitor the output from ESP device via serial port.

Now, upload your second program via OTA. But still fail due to No response from device.

Now, open Windows Security and Allow espota.exe to communicate through Windows Defender Firewall.

Upload again, and Done uploading.

(In the various steps, the assigned ip of the ESP device may be changed. Double check the ip in Putty and select the Network port accordingly.)

Install ESP32/ESP8266 to Arduino IDE on Ubuntu 20.04, with setup Pythton & serial

After install JDK (OpenJDK) and Arduino IDE on Ubuntu 20.04, you can add support of ESP32 (or ESP8266).

May be you will be with Python 2 related error of:
exec: "python": executable file not found in $PATH
ModuleNotFoundError: No module named 'serial'

In 20.04 LTS, the python included in the base system is Python 3.8. Python 2.7 has been moved to universe and is not included by default in any new installs. (referene: Ubuntu 20.04 LTS (Focal Fossa) release notes)

Here show how to fix it:


First, install board to Boards Manager:

Menu > File> Preferences
Enter the url in the "Additional Board Manager URLs":
https://dl.espressif.com/dl/package_esp32_index.json (for ESP32)
http://arduino.esp8266.com/stable/package_esp8266com_index.json (for ESP8266)

To enter more than one URL, separate it with a comma.

Menu > Tools > Board > Boards Manager…
Search and install ESP32 (or ESP8266)

When you build your code for ESP32/ESP8266, if you report with error of :
exec: "python": executable file not found in $PATH

It's because Python 2 is not installed on Ubuntu 20.04. You can create a symlinks /usr/bin/python to python3 by installing python-is-python3.

$ sudo apt install python-is-python3

Optionally, you can prevent Python 2 from being installed as a dependency of something in the future:

$ sudo apt-mark hold python2 python2-minimal python2.7 python2.7-minimal libpython2-stdlib libpython2.7-minimal libpython2.7-stdlib

Then you may be report with error:
ModuleNotFoundError: No module named 'serial'

Because pyserial is not installed in Python 3 by default. Install with pip:

$ sudo apt install python3-pip
$ pip3 install pyserial

Additionally, if you cannot download your code to board caused by:
avrdude: ser_open(): can't open device "/dev/xxx": Permission denied

Add permission to your user:

$ sudo usermod -a -G dialout <username>
$ sudo chmod a+rw /dev/xxx

---

Next:
- ESP32-DevKitC + 2.8inch 240x320 SPI TFT (ILI9341) using TFT_eSPI library
- ESP32 + 1.3 inch 240x240 IPS LCD (ST7789 SPI interface), using TFT_eSPI library
- NodeMCU (ESP8266) + 1.44" 128x128 TFT with ST7735 SPI driver (KMR1441_SPI V2), using ssd1306 library

- ATGM336H-5N/ESP32, read GPS position using TinyGPS++

- BasicOTA: Program ESP32 (or ESP8266) via ArduinoOTA, on Windows 10/Arduino IDE

- Program ESP32-CAM using FTDI adapter

Install Arduino IDE 1.8.13 on Ubuntu 20.04

To run Arduino IDE, you have to install Java on Ubuntu, refer last post Install JDK (OpenJDK) on Ubuntu 20.04.


Visit https://www.arduino.cc/ to download Linux 64 bits version.

Extract the downloaded file and more to where you want. Switch to the folder and run:
$ sudo ./install.sh

You will be reported with error of:

An error occurred while uploading the sketch
avrdude: ser_open(): can't open device "/dev/ttyACM0": Permission denied

You can add you (the user) to the group own permission of the upload port:

$sudo usermod -a -G dialout <username>
$sudo chmod a+rw /dev/ttyACM0

change username and ttyACM0 according to your setup.

logout and login.

---

Basically, the steps to install Arduino IDE on Ubuntu 20.04 are same as install on previous version of Ubuntu. But if you target to develop for ESP32/ESP8266, very likely you will be with error of:
exec: "python": executable file not found in $PATH
ModuleNotFoundError: No module named 'serial'

Check next post - Install ESP32/ESP8266 to Arduino IDE on Ubuntu 20.04, with setup Pythton & serial

Arduino Uno + RFID-RC522, MFRC522 library example DumpInfo

This post show how Arduino Uno + RFID-RC522 (RFID reader) to dump info of RFID key and RFID card, using Arduino RFID Library for MFRC522.

Arduino library for MFRC522 and other RFID RC522 based modules (https://github.com/miguelbalboa/rfid) read and write different types of Radio-Frequency IDentification (RFID) cards on your Arduino using a RC522 based reader connected via the Serial Peripheral Interface (SPI) interface.

Install MFRC522 library to Arduino IDE:

You can download ZIP file from the library web page, and it to Arduino library, read the video below. After library added, it will be in the folder your_Documents\Arduino\libraries\,


and fritzing parts is in your_Documents\Arduino\libraries\rfid-master\doc\fritzing\.

Connect Arduino Uno and RFID-RF522 module:

In Arduino IDE, Open Example of DumpInfo in MFRC522:

/*
 * ----------------------------------------------------------------------------
 * This is a MFRC522 library example; see https://github.com/miguelbalboa/rfid
 * for further details and other examples.
 * 
 * NOTE: The library file MFRC522.h has a lot of useful info. Please read it.
 * 
 * Released into the public domain.
 * ----------------------------------------------------------------------------
 * Example sketch/program showing how to read data from a PICC (that is: a RFID
 * Tag or Card) using a MFRC522 based RFID Reader on the Arduino SPI interface.
 * 
 * When the Arduino and the MFRC522 module are connected (see the pin layout
 * below), load this sketch into Arduino IDE then verify/compile and upload it.
 * To see the output: use Tools, Serial Monitor of the IDE (hit Ctrl+Shft+M).
 * When you present a PICC (that is: a RFID Tag or Card) at reading distance
 * of the MFRC522 Reader/PCD, the serial output will show the ID/UID, type and
 * any data blocks it can read. Note: you may see "Timeout in communication"
 * messages when removing the PICC from reading distance too early.
 * 
 * If your reader supports it, this sketch/program will read all the PICCs
 * presented (that is: multiple tag reading). So if you stack two or more
 * PICCs on top of each other and present them to the reader, it will first
 * output all details of the first and then the next PICC. Note that this
 * may take some time as all data blocks are dumped, so keep the PICCs at
 * reading distance until complete.

Install Arduino driver on Windows 10

Due to any reason, you cannot install the Arduino driver on Windows, you can try to update the driver manually in your Device Manager.

• Plug in your board and wait for Windows to begin it's driver installation process. After a few moments, the process will fail, despite its best efforts
• Click on the Start Menu, and open up the Control Panel.
• While in the Control Panel, navigate to System and Security. Next, click on System. Once the System window is up, open the Device Manager.
• Look under Ports (COM & LPT). You should see an open port named "Arduino UNO (COMxx)". If there is no COM & LPT section, look under "Other Devices" for "Unknown Device".
• Right click on the "Arduino UNO (COmxx)" port and choose the "Update Driver Software" option.
• Next, choose the "Browse my computer for Driver software" option.
• Finally, navigate to and select the driver file named "arduino.inf", located in the "Drivers" folder of the Arduino Software download (not the "FTDI USB Drivers" sub-directory). If you are using an old version of the IDE (1.0.3 or older), choose the Uno driver file named "Arduino UNO.inf"
• Windows will finish up the driver installation from there.
