The next basic test is to see if the board can be detected by the operating system and load drivers for it.

Linux Drivers

Linux drivers should already be installed on most Linux systems. Plug the ESP32 Devkit board into the Linux PC using a USB cable and enter the following command to find the name of the port that the board is connected to.

A more basic and manual test to see if the drivers on a Linux computer have loaded is to first enter the following command in a terminal window without the board plugged into the PC.

Now plug the board in and run the same command again. The new device starting with tty that appears in the list is the ESP32 Devkit board. For example, it appears as ttyUSB0 on my Linux Mint computer.

Also try the following command before and after plugging the board in to see if the board is configured as a ttyUSB device.

Download and Install Windows Drivers

Drivers must be installed on Windows systems for the Silicon Labs CP2102 USB-to-UART bridge chip. After drivers have been loaded, the board appears as a virtual COM port (VCP) on the PC.

Download CP2102 Driver

Go to the CP210x USB to UART Bridge VCP Drivers page and select the driver for your version of Windows. For Windows 7 and 10 download from the Download VCP link as shown highlighted by a red dot below.

Download a Serial Port Terminal Program for Windows

A terminal program is needed to connect to the Lua interpreter on the ESP32 board via the virtual COM port.

If you don't have a serial port terminal program installed on your PC, you can download Tera Term for Windows. Go to the Tera Term download page and download the newest release of Tera Term. Download the zip file, e.g. teraterm-4.96.zip.

Extract the teraterm folder from the downloaded zipped file and place it in a convenient location, e.g. on your desktop.

To run Tera Term, open the folder, e.g. teraterm-4.96, then find and double-click ttermpro.exe.

Serial Port Terminal Program for Linux

Minicom is a text based serial port terminal program for Linux that is run from the command line. On Ubuntu based Linux distributions such as Linux Mint, enter the following command to install Minicom.

Testing the ESP32 Devkit Serial Port Connection

In this test the serial port terminal program is connected to the ESP32 Devkit board. When a connection is made and the board is booted up, diagnostic messages and the Lua prompt will be seen in the terminal window.

Connecting to the ESP32 Devkit using Tera Term in Windows

Before connecting, start Device Manager again and expand the Ports (COM & LPT) item. Find the item called Silicon Labs CP210x USB to UART Bridge (COM4) where COMx at the end shows the COM port number of the ESP32 Devkit board. Now that we know the COM port number, we can connect to the board.

Start Tera Term and close the new connection dialog box that pops up. On the top menu select Setup → Serial port.... In the dialog box that opens, select the COM port that you found in device manager and the following parameters: Baud rate: 115200, Data: 8 bit, Parity: none, Stop: 1 bit and Flow control: none as shown in the image below.
