Converting Mac Address to Serial Number

In various IoT projects, it's essential to identify and track devices. One way to do this is by converting a MAC (Media Access Control) address to a serial number. In this article, we'll explore how to convert a MAC address to a serial number using the ESP8266 board.

Setting Up the Serial Port

To begin, we need to set up the serial port on our ESP8266 board. This allows us to print the output of our program and access various functionality needed for wireless connectivity. For this tutorial, we'll include the ESP8266WiFi library, which provides all the necessary functions for connecting to a WiFi network.

Getting the MAC Address

The code for this tutorial is straightforward since we already have a function to retrieve the MAC address of the ESP8266. We used a NodeMCU board, a popular and affordable ESP8266 development board, to test our program.

Understanding MAC Addresses

A MAC address is a 48-bit unique identifier that represents a network adapter's hardware address. It's typically represented in hexadecimal format, with each two hexadecimal digits separated by a colon (:). The first 24 bits of the MAC address identify the manufacturer, while the second 24 bits are a serial number assigned by the manufacturer.

Converting the MAC Address to Serial Number

To convert the MAC address to a serial number, we can use the unique value associated with each network adapter. This process is crucial in identifying and tracking devices in various IoT projects.

In this article, we've explained how to get the MAC address of an ESP8266 board. We've also discussed what a MAC address is and its importance in identifying and tracking devices. By converting a MAC address to a serial number, you can uniquely identify your network adapters and track them in various IoT projects.
