With your suggestion,, you are safe and whatever board you send will always work. You are asked to provide a new board, which will not work because it has a new MAC. the accident has happened and the board is destroyed.

Let’s say you make a product and sell it to 100 or thousands, or more customers all over the world using Ebay, Amazon, KickStarter or other mass selling companii. With your solutions, i can replace 25 chips or more in the same projects, without modifying the new code.

Learn ESP32 with Arduino IDE (eBook + Video Course)Ī very interesting idea and i personally intend to use it in my projects.Īs some of my projects are MAC address dependent, in the unfortunate case of a chip failure, i have to go and change the code again for the new chip and put the new MAC address of the chip.

Check Using Command Line (CLI) Check Using Web GUI Step 1: Click Network Administration -> Port Settings -> Address Tables Step 2: Click 'Dynamic Address Table' to check the mac address of all devices connected to this switch. Learn more about the ESP32 and ESP8266 boards: We can find the mac address of the devices connected to the switch by using following methods.

Uint8_t newMACAddress = Īfter uploading the code, open the Serial Monitor at a baud rate of 115200. The following code sets a custom MAC Address for the ESP32 board. So, every time you reset the board, or upload a new code, it will get back to its default MAC Address.

However, as explained previously, this doesn’t overwrite the MAC Address set by the manufacturer. In some applications, it might be useful to give your boards a custom MAC Address. Set a Custom MAC Address for ESP32 and ESP8266 That’s it! Now, you know how to get your ESP32 or ESP8266 board MAC Address. The MAC Address should be printed in the Serial Monitor as shown in the following figure. Python3 import requests import argparse print(' Welcome') def getarguments (): parser argparse.ArgumentParser () parser.addargument ('-m', '-macaddress', dest'macaddress', help'MAC Address of the device. Complete Instructions to Get and Change ESP MAC Address: Īfter uploading the code, open the Serial Monitor at a baud rate of 115200. We will use requests module to work with this API. To get your board MAC Address, simply upload the following code to the ESP32 or ESP8266. So, you need to include the code to set a custom MAC Address in every sketch. However, every time the board resets, it will return to its original MAC Address. MAC Addresses are assigned by manufacturers, but you can also give a custom MAC Address to your board. MAC Addresses are made up of six groups of two hexadecimal digits, separated by colons, for example: 30:AE:A4:07:0D:64. MAC Address stands for Media Access Control Address and it is a hardware unique identifier that identifies each device on a network.
