Setting Serial Communication in PuTTY on Linux Setting Serial Communication in PuTTY on Windows Remember to select exactly the same serial port you have identified in steps above. Below are example screenshots of setting the port and such transmission parameters (in short described as 11-N) on Windows and Linux. Baud rate = 115200 (if needed, change this to the default baud rate of the chip in use), data bits = 8, stop bits = 1, and parity = N. Run terminal and set identified serial port. You can use other serial programs and set communication parameters like below. In this example we will use PuTTY SSH Client that is available for both Windows and Linux. The default console baud rate on ESP32 is 115200. You can do this using a serial terminal program by checking if you get any output on the terminal after resetting ESP32. Now verify that the serial connection is operational. Make sure you re-login to enable read and write permissions for the serial port. Under normal circumstances, the drivers should be bundled with an operating system and automatically installed upon connecting the board to the PC.įor devices downloaded using a USB-to-UART bridge, you can run the following command including the optional argument to define the baud rate. The drivers above are primarily for reference. Please check the board user guide for specific USB-to-UART bridge chip used.

If device driver does not install automatically, identify USB-to-UART bridge on your ESP32 board (or external converter dongle), search for drivers in internet and install them.īelow is the list of USB to serial converter chips installed on most of the ESP32 boards produced by Espressif together with links to the drivers:ĬP210x: CP210x USB to UART Bridge VCP Drivers Connect ESP32 to PC Ĭonnect the ESP32 board to the PC using the USB cable.
