The Serial Number is on the Device Information page. Go to the Phone Configuration page and click on the IP address of the registered phone.

CCM keeps the serial numbers on the IP phone web page. Just to confirm what was explained in the introduction section, we can check if the first 24 bits of the MAC correspond to the manufacturer of the ESP8266, which is Espressif. RE: Obtain MAC address from Serial Numbers. You should get something similar to figure 1.įigure 1 – Output of the function to get the MAC of the ESP8266. To test the code, just upload it to the ESP8266 and open the Arduino IDE console.

You can check the full working code bellow, which also includes the empty loop function. To get the MAC dress of the ESP8266, we simply call the macAdress method on the WiFi global variable, which will return the MAC address in the hexadecimal format mentioned early. Then, in our setup function, we open the serial port, so we can print the output of our program. Since we only want to print the MAC, we will do all the coding on the setup function and leave the main loop empty.įirst, we include the ESP8266WiFi library, which we typically use to access all the functionality needed for the ESP8266 to connect to a WiFi network. The code for this tutorial is very simple, since we already have a function to get the MAC of the ESP8266. The tests were performed using a NodeMCU board, a very cheap and easy to use ESP8266 board. You can read more about MAC addresses here. Type ipconfig /all (note the space between the g and /). Select Run or type cmd into the search bar at the bottom of the Start menu to bring up the command prompt. The first 24 bits of the MAC are the identifier number of the manufacturer and the second 24 bits are a serial number assigned by the manufacturer. To find the MAC address on your Windows computer: Click on the Start menu in the bottom-left corner of your computer. In terms of format, MAC addresses are 48-bit in length and typically represented in hexadecimal format, with each two hexadecimal digits separated by “:”. Taking in consideration the OSI model, MAC addressing works at a layer (layer 2) lower than IP addressing (layer 3). So, MAC addresses are hardware addresses that uniquely identify a network adapter. Hi to all, I have some phone traveling to my office, i have the serial numbers only. OUIs and MAC addresses may be colon-, hyphen-, or. Type or paste in a list of OUIs, MAC addresses, or descriptions below. It uses the Wireshark manufacturer database, which is a list of OUIs and MAC addresses compiled from a number of sources. But, just as a quick explanation, the MAC address is a unique value associated with a network adapter. The Wireshark OUI lookup tool provides an easy way to look up OUIs and other MAC address prefixes.

The objective of this short post is to explain how to get the MAC address of the ESP8266.Įxplaining in detail what is a MAC address is outside of the scope of this post.
