Introduction: ESP8266 Static IP (WIP)

ESP8266 Static IP (WIP)

(If your Wi-Fi network is already configured in some way, you may need to talk to your Network Administrator.)

Part of the goal of our project is to assign each ESP8266 its own static IP address to make it easier to keep track of the devices and connect to their webpages.

An IP address is an address that can be used to access and communicate with devices on a network. There are 2 forms of IP addresses, but the most common form is IPv4, which looks something like this: 192.168.1.1. The format is 4 sets of numbers from 0-255, separated by periods, BUT*** it is important to note that some specific numbers have special uses and meanings, some of which you can find information about here: https://en.wikipedia.org/wiki/IPv4#Special-use_ad...

These addresses are typically automatically assigned by a DHCP server. Most homes and high schools use their router as their DHCP server, meaning that the router will automatically assign IP addresses, using Dynamic Host Configuration Protocol (DHCP), to devices as they connect to the network.

Our goal here, however, is to use Static IP addresses, which are IP addresses that are NOT automatically assigned by a DHCP server. The reason for this is that your router isn't set up to give any certain device the same IP address, so it'll use some random address that happens to be available at the time. While this is perfectly fine for most network use, this can be a hassle to deal with when you're doing something like we're doing here and you need to connect to a locally-hosted webpage using the device's IP.

Step 1: Getting Into Your Router's Control Panel

If your router does have some kind of configurations in place, this is the part where you will need to talk to your Network Administrator (whoever set up the configurations, such as a parent/guardian, teacher, tech/IT department, etc.).

In order to get available static IP addresses, you'll either need to find an available range in your current configuration or set up a range yourself. To do this, you'll need to go into the control panel of your router. The way you do this will vary depending on what router you have, but you should be able to look up "how to access {your router name or brand} control panel" and find a tutorial.

Once you're into your router's control panel, find its DHCP settings (which may be under a broader category called "Local Network" or something similar).

Step 2: Reserving Static Range in DHCP

If your router DOES have any special DHCP configurations or reservations set up, then:

  • Either find a range of IP addresses that aren't currently being used in the already reserved range and make a note of these
  • OR make the current range bigger (you can find how to do this in the steps below)

If your router does NOT have any special DHCP configurations or reservations set up, then follow these steps:

  • Your router is told to assign IP addresses in a certain range, like from 192.168.1.1 to 192.168.1.255, so we want to restrict this range so that we have a range of available addresses that aren't automatically assigned.
  • Set the range to start higher by changing the number in the last set of numbers. For example, change 192.168.1.1 to 192.168.1.25. This means that your router will no longer automatically assign IP addresses in the range from 192.168.1.1 to 192.168.1.25

We can now manually assign these addresses!

Step 3: Assigning a Static IP to an ESP8266

There are 2 main ways of actually assigning a static IP to an ESP8266: through the router or through the ESP8266.

Requesting a specific address from the router through code on the ESP8266 (my personal preference):

This is a good guide: https://circuits4you.com/2018/03/09/esp8266-static... but the basics are:

  • Put the following include statements at the very top of your code:
  • Then call these methods, where x is the static IP (separate the 4 sets of numbers with commas instead of periods) and y is the IP address of your router (which is also called a gateway):

Using the ESP8266's Media Access Control (MAC) address in the router's settings:

ESP8266 NodeMCU Static/Fixed IP Address - Working & Testing

For your ESP8266 NodeMCU board , this tutorial shows how to set a static/fixed IP address. If you're using your ESP8266 to run a web server or a Wi-Fi client and every time you restart it, it gets a new IP address, you may use this tutorial to assign a static/fixed IP address.

Static/Fixed IP Address Sketch

We'll use the ESP8266 Web Server code as an example to show you how to fix your ESP8266 IP address. You should be able to fix your IP address by the conclusion of our discussion, regardless of the web server or Wi-Fi project you're working on.

Copy the following code to your Arduino IDE, but do not upload it yet. To make it work for you, you'll need to make some changes.

Freenove Ultimate Starter Kit for ESP32-WROVER (Included) (Compatible with Arduino IDE), Onboard Camera Wireless, Python C, 814-Page Detailed Tutorial, 240 Items, 127 Projects

Note : If you upload the next sketch to your ESP8266 board, it should assign the fixed IP address 192.168.1.184 automatically.

Setting Your Network Credentials

You need to modify the following lines with your network's SSID and password.

Setting ESP8266 Static IP Address

Then, outside of the setup() and loop() procedures declare the following variables with your own static IP address and gateway IP address:

The next code, by default, assigns the IP address 192.168.1.184 , which works with the gateway 192.168.1.1 .

FREENOVE Ultimate Starter Kit for ESP8266 (Included) (Compatible with Arduino IDE), ESP-12S Onboard Wi-Fi, MicroPython C Code, 714-Page Detailed Tutorial, 218 Items, 109 Projects

Important : On your local network, you need to use the corresponding gateway and an available IP address.

You need to assign the configurations to your ESP8266 in setup() by using WiFi.config() method.

Note:  the “ primaryDNS”  and “ secondaryDNS “   parameters are optional and you can remove them.

After uploading the code to your board, open the Arduino IDE Serial Monitor at 115200 baud rate, restart your ESP8266 board, and the IP address you specified earlier should be assigned to your board.

To assign a fixed IP address to your ESP8266, you may take this example and add it to all of your Wi-Fi sketches.

Assigning IP Address with MAC Address

If you tried using the previous example to assign a fixed IP address to the ESP8266 and it didn't work, we recommend assigning an IP address directly in your router settings using the ESP8266 MAC Address .

Upload the following code to the ESP8266 board:

Arduino UNO R4 WiFi [ABX00087] - Renesas RA4M1 / ESP32-S3 - Wi-Fi, Bluetooth, USB-C, CAN, DAC, OP AMP, Qwiic Connector, 12x8 LED Matrix

It prints the ESP8266 MAC Address on the Serial Monitor in setup() :

ESP32 MAC address

In our example, the MAC Address of the ESP8266 is “ B4:E6:2D:97:EE:F1 “. You'll need the MAC Address in just a bit, so copy it.

Router Settings

When you login to your router's admin page, you should see a page or menu where you can assign an IP address to a network device. Each router has its own set of menus and configurations. As a result, we are unable to give instructions for all available routers.

amomii UNO Microcontroller (Compatible with Arduino IDE), Coding and Hardware Tutorials, USB Type-C Connector, 3D Printable Accessories, Example Projects and Code, Higher Power Handling Capabilities

We recommend searching “ assign IP address to MAC address ” followed by the name of your router. You should be able to find some instructions that show you how to assign an IP address to a MAC address for your specific router.

In summary, you should be able to assign your desired IP address to your ESP8266 MAC address (for example, B4:E6:2D:97:EE:F1) by going to your router's configuration menu.

You should be able to assign a fixed/static IP address to your ESP8266 after following this tutorial. If you own an ESP32, you should read this guide:  Set ESP32 Static/Fixed IP Address .

Getting a Fixed / Static IP Address for ESP8266

Do you have a question ?

If you want the ESP8266 (or any other network connected device) to always have the same IP address then the best way is leave the device configured to get an IP address using DHCP and assign the desired IP address in the router. Most routers allow you to associate a specific IP address with a particular MAC address.

This has the advantage that the router is in control of IP address allocation, and and if you want multiple devices all with different IP addresses you can set them all in one place, in the router, rather than having to hard code different IP addresses in each device.

You can TRY this

I've tried with varying degrees of success

However as Perry says, by far the best way is to assign a fixed IP addresss in your router

Made the sketch like you suggested, but the esp8266 still comes with an ip-adress, that is not in my range. (192.168.4.2 instead of 192.168.178.xx ) as I programmed it to do. Any suggestion?

In line 88, try using

WiFi.config(staticIP, gateway, subnet, dns);

instead of WiFi.config(staticIP, subnet, gateway, dns);

Also, make sure your gateway address is correct. Mine was wrong and the ESP8266 was getting the previous address.

How to set up a static IP on the ESP8266 or ESP32

We continue with the entries dedicated to the ESP8266 and the ESP32 . This time we will see how to set up a static IP in our connection.

We will refer to the ESP8266, but the same code is compatible for the ESP32, adjusting the name of the libraries. At the end you have the code for both the ESP8266 and the ESP32.

In the two previous entries we have seen how to connect to an existing WiFI network in STA mode and how to generate our own WiFi network in AP mode.

Now that we have our ESP8266 connected to the WiFi network, the next need will be to connect to our device, for which we will have to be able to find it within the network . Or, in other words, we need to know its local IP address.

So far, we had shown the IP address as soon as we connected by serial port. But it is not very practical to have to have a computer or a screen connected to the device to see which IP address the router’s DHCP has assigned us, right?

We have several options available to find our device. One is to use a device scanner, another is to use mDNS but, the most secure and robust is to set up a static IP on the ESP8266.

Fortunately, it is very easy to set up a static IP on the ESP2866 with the ‘config’ function of ESP8266WiFi.

Note that the order of the parameters is different from the Arduino WiFi library (the ESP8266WiFi and Arduino WiFI libraries are similar, but not identical). Keep this in mind if you are looking for tutorials on the internet, because sometimes they get confused.

This function must be called immediately after WiFi.begin(), which starts the connection with DHCP enabled. With WiFi.config() we can configure the IP, gateway, subnet and, optionally, the dns.

In the case of the ESP32, the library is simply called ‘WiFi’.

Example in STA mode

Let’s see an example of how to set up a static IP in STA mode, that is, connecting to an existing WiFi. The following example would connect to the network, and set the IP to 192.168.1.200.

It is important to note that the router must be configured to assign us the desired IP. Typically, this means that it must be outside the range of IPs designated for DHCP.

Example in AP mode

In AP mode, setting up the static IP is less critical than in STA mode. After all, we are generating our own WiFi and we can set the IP we want.

Still, the WiFi.softAPConfig() function allows us to change the parameters within the generated WiFi network. The following example shows the configuration, where we also change the address of the ESP8266 to 192.168.1.200.

Summary Example

As we did in the previous entries, if we divide the code into different files, the code is summarized and easier to maintain.

An additional file that we will call ‘ESP8266_Utils.hpp’ containing the connection functions.

A file with the data of our WiFi network.

That’s it! In the next entry we will see another way to find our device with mDNS . See you soon!

ESP8266 example: Wi-Fi Access point, static IP, web-server and remote GPIO control

ESP8266 example: Wi-Fi Access point, static IP, web-server and remote GPIO control

After testing the basic Wi-Fi connectivity options  of the ESP8266 it is now time to explore some of the more interesting features of the chip. In the sketch below the NodeMCU development board creates a Wi-Fi access point and starts a web-server. A HTML page hosted on the web-server displays analog data from a photocell and allows you to control remotely a LED via Wi-Fi from a web-browser on your phone or PC. As in the previous examples, I am using the Arduino IDE to program the ESP8266 board .

The LED is connected to NodeMCU pin D1 (ESP8266 GPIO5) through a 1k resistor. One leg of the photocell is connected  to 3.3v and the other one to ground trough a fixed 10k Ohm (or higher) resistor. There is also a connection from the NodeMCU pin A0 (ESP8266 ADC0) to the point between the fixed pull-down resistor and the variable photocell resistor.

ESP8266 Web Server

Load the sketch, open the serial monitor and restart your NodeMCU module. You should see the following output:

Now open the Wi-Fi settings of your phone, or PC. You should see a new Wi-Fi network, called “ESP8266” (assuming you left the defaults in the sketch above). Connect to it using the password from the sketch, open a new browser window and type http://42.42.42.42 in the address bar. This is the static IP we defined earlier in the sketch for the root of the web-server. You should see a page like the one below:

ESP8266-SoftAP-WebServer

You can click on the link to toggle the LED now: the page should refresh and the LED should respond to your command!

Hi, I’m starting to use ESP8266 and I’ve been very useful for your example thank you. I do not know HTML so I wonder if, once connected to the module, I can set ssid and password in the memory of the module itself by introducing this data into the edited web page. Thanks

Great tutorial, code worked first time. Thanks!

I love people that say Great and work first time; however I found it will not compile reason being in line 1 @ the end ” */” as you have it at line 3, because of that line 2 does not compile. Of course with me I got the web server working as per your example but in terminal mode “Arduino” what is all the rubbish text before displaying Configuring access point… AP IP address: 42.42.42.42 HTTP server started Is it just junk when you reset the 8266 noise configuring registers etc. I haven’t manage yet to get the led to blink either way round but I must say this is lovely work by yourself. It gives an insight to what I want to do. Many thanks but please delete that */ and its perfect.

Great tutorial – worked first time. Couple of points:

Chrome rejects http://42.42.42.42 and brings up a search page. Works fine with firefox.

The page does not automatically refresh. In fact it goes and stays blank when one toggles the LED and one needs to “manually” refresh the page.

Please tell me that if I add some javascript code and verify it, it give error

I want to control two led can you help me to add codes of another led in the same sketch and send it to me through this email [email protected] .i’ll be grateful

I am getting this error: “missing terminating ” character” at line 133 “,. I’m fairly new at this although I do know HTML5.

how can i send data from webpage like textbox to the nodemcu

Great tutorial, worked first time. Refresh and LDR brightness perfect, thanks

I would like to use this sketch with the Adafruit Feather Huzzah with ESP8266. However, I’m not sure what changes need to be done to make it compatible. Any advice?

Thank you for the answer to life, the universe and everything! 😉 At last I manage to change annoyed 192.168.4.1!

I’m not getting the http://42.42.42.42 you mentioned. I get an ip which is within my network. I can access using 10.0.0.44

Great tutorial, worked first time. Thanks

Great tutorial, worked first time. Thank you.

Hi, Thanks for your help. I uploaded the above code and created an access point with web server on it successfully. Now, if I want to send some commands remotely via WiFi, e.g. sending commands or data from my distant laptop/phone to the arduino/ESP8266 in order to control the sensors, what should I do?

Best, Jamshid

Hi Just what I looking for, a foot up to finding out about ESP8266 control over the net. Thank you. Tried to compile the sketch as it is but got an error on this line IPAddress apIP(42.42.42.42); // Defining a static IP address: local & gateway // Default IP in AP mode is 192.168.4.1

The error says ; exit status 1 too many decimal points in number

Thanks again for your tutorial.

brilliant and clear – thanks

Can you remove the below form your code? it does not compile 🙂 Outta help people….

Setting StaticIP address on ESP8266

Hi. Using the Blynk.begin command can you set your Wemos or ESP8266 to a static IP address (instead of using DHCP every time) so that when it powers up it connects faster ? I can’t seem to find any info on this.

:slight_smile:

In order to set static IP Address into ESP8266 you have to send it the following AT Command:

AT+CIPSTA=“ip module”,“ip gateway”,“subnet mask”

e.g.: AT+CIPSTA=“192.168.1.160”,“192.168.1.1”,“255.255.255.0”

where: .160 is the address of the ESP8266 and .1 is the address of the router.

You can send this command to the ESP 8266 just once.

The program the I use to send commands to ESP8266 is:

The command are placed on the top bar of the Serial Monitor of the IDE of Arduino. The Serial Monitor MUST be placed in Both (NL & CR) and the baud rate of the program must be the same of the baud rate of ESP. Try with a simple AT command to verify if all is OK. The ESP must respond with an OK. The module is connected to a soft serial (pins 2 and 3). Hope this can be useful. Ciao, Giancarlo

Correct !! I forgot to put in evidence that I use the ESP as a shield !!

thanks guys - so you can setup static IP address and attributes as per your program ONCE then ESP8266 remembers them even if powered off ? With respect to code example,if I have a Wemos then I change serial to RX 1, and 2 respectively ?

if you only using a Wemos i think you should check the manual Ethernet sketch @Lichtsignaal suggested…

@mars Yes, the ESP stores the last received setting (e. g. static IP) in its non volatile memory so it remembers even if powerd off. Regarding the serial lines, you can use the most suitable lines for your hardware. Ciao, Giancarlo

Hi - I tried to modify the blynk Ethernet sketch for setting static ip for esp8266 but can’t seem to get it to work. Anyone done it successfully without using AT commands ie doing it with blynk.begin api ? If so can you pls share

thanks Costas - this works, appreciate that.

I assume doing it this way does NOT keep the static IP address within the ESP8266 even when switched off, i.e. I need to setup staticIP eachtime Blynk runs ? Unlike in the case with using AT commands the ESP8266 remembers the StaticIP settings even when switched off.

Is this correct ?

To be honest I’m not really sure if the IP is saved in none volatile memory like the ssid and pwd. If you are running the sketch then it will always have the same IP when power is restored.

Question on a totally different topic - but I know you understand a lot about given historical posts. I am using the RTC widget in my code and its all compiles fine etc and displays formatted time and date in LCD widget but it always start with time 0.0.0 and date 1.1.1970 - even though I select correct timezone in widget. I am using a local Blynk server and wonder if there is anything special or different I need to do because I am using a local Blynk server ?

It is because the ESP8266 clock hasn’t been sync’d with the server. The default is for the sync to be at 5 minute intervals.

The RTC widget uses this library https://github.com/PaulStoffregen/Time and you can change the sync interval with setSyncInterval( interval), where interval is some seconds.

I have found it doesn’t always sync though if you have a lot of virtualWrite’s and other pin syncing when the ESP boots up.

Extract of a fix below that uses a SimpleTimer every 1 second to try and sync the time, once the time is sync’d the SimpleTimer is deleted.

int clockcounter = 3; // just happens to be our 3rd timer but must be set as an integer to be able to disable the timer

Edit: I should have added that you must include the following line in loop()

timer.run(); // plus include required libraries at the top of your sketch

Top of your sketch:

And a “perfect” loop is:

:frowning:

It takes just a few seconds for the sync to take place on our system.

Maybe I should give you a full sketch to try.

Just a thought, is your local server something like a Pi that has been restricted to LAN routing?

hi - i’m running local server on windows 10 pc. I realized for some reason the interrupt function was not working so I created a little flag checking function which then worked - but then i realized only GMT+11 is available from RTC widget on Blyk App and it should be GMT+10 for Australia/Sydney — I’ve raised another post issue on it earlier.

If you can share the entire script that would be great.

See below: the time in LCD widget is 19:26 which is GMT+11, but the time in the history graph is GMT+10 ! really weird – I don’t know why.

how to assign static ip address to esp8266

@mars Hi Mars, I report you a note that I wrote in a former post of some days ago:

… the RTC shows 1/1/1970 for the first 5 minutes if you miss this line of code:

while(Blynk.connect() == false);

equivalent to:

This line has to be inserted after Blynk.begin and before rtc.begin:

In such a way the RTC hows immediately the correcet date and time.

Regarding the code to format date and time, in my opinion, the most elegant lines of code are:

If you don’t want leading zero, exclude the 0 from the formatting section of sprintf.

Date and Time are array of char:

Regarding the static IP Address of ESP8266, I have verified that if you assign it with AT commands it is stored in the non volatile memory of ESP.

I hope it could be useful. Ciao, Giancarlo

Unable to Assign IP Address to an Arduino Board Connected to ESP8266

Description.

When deploying code on an Arduino ® board connected to an ESP8266 chip, Simulink ® generates this error:

Failed to assign IP address to ESP8266 .

Try these options sequentially until the IP address is assigned to ESP8266:

Ensure that a power supply of 3.3 V is provided to the ESP8266 chip. If a voltage higher than 3.3 V is supplied, the chip might be damaged.

Make sure the serial port using which the ESP8266 is connected to the Arduino board matches the serial port specified in the Configuration Parameters > Hardware Implementation > Target hardware resources > WiFi properties > Hardware Serial Port .

For example, the Arduino Mega 2560 board has serial port 1 on RX pin 19 and TX pin 18. If the TX and RX pins of ESP8266 are connected to the RX pin 19 and TX pin 18 on the Arduino board, set the Hardware Serial Port parameter to Serial 1 .

how to assign static ip address to esp8266

Reset the ESP8266 chip, wait for approximately one minute, and try again.

Check if the firmware version of ESP8266 is AT version 1.3 or higher. If not, upgrade the firmware.

Unplug the Arduino board, plug it back in, and then deploy the model again.

If the error still persists, assign a static IP to the board. To assign a static IP address, go to WiFi properties and select Use static IP address and disable DHCP . In the IP address parameter specify an IP address to the board, click Apply , and deploy the model again.

How to set a static internal IP in Ubuntu

Quick links, how to set static internal ip in ubuntu using the gui, how to set static internal ip in ubuntu using the terminal and text editor.

There comes a time when you might have to configure Ubuntu or any other Linux distribution with a static IP address. While you can't change your external static IP address, since it's the one your internet service provider provides, you can change your internal one. This is the IP address used on your network inside your home or office.

Though many tasks on Ubuntu usually require you to visit the terminal app and deal with lines of text, changing your internal IP is easy. You can do this through the settings app and the Graphical User Interface (GUI). Of course, if you want, you can also swap things out by going through the terminal. Here's how.

Without any technical know-how or knowledge, you can set a static IP in Ubuntu through the settings app. Just note, you will have to use the terminal once to find a range of IP addresses that you can assign. Once you do that, you just tap the Windows Key or the Superkey on your device and search for Settings . Once the app is open, proceed with the steps below.

  • If you're connected to the internet via Wi-Fi, choose Wi-Fi . If you're connected via Ethernet, select Network.
  • Once the interface is open, click the settings icon next to the network you're connected to.
  • From the list of tabs at the top, choose IPv4.
  • Under ipv4 method, be sure to choose Manual.
  • Under Addresses, enter the IP address, the Netmask, and the Gateway you want to use. For finding IP addresses that'll work on your network, you can proceed with the steps below.
  • Open a terminal session. With Ctrl, Alt, and T. Install net-tools with the command sudo apt install net-tools.
  • In this case, we have an inet of 192.168.1.176 and a netmask of 255.255.255.0. We can enter those numbers and can calculate the usable range using this website .
  • When you've calculated the usable range of addresses, choose a valid IP address that falls within this range. Then, you can click Apply at the top.

Any changes you apply will automatically go into effect. If you want, you can also use the terminal to confirm your IP address. Launch it with Ctrl, Alt, and T on your keyboard. Once launched, enter the command ip addr or ip a . You should see an interface IP address listed.

If you're a bit more technical and want to set a static IP in Ubuntu using the terminal, that is possible. You'll have to edit some lines of text and go through a few extra steps, but here's how:

  • Display information about your network. Use the command nmcli connection show. You'll see a network name, a UUID, a Type, and a Device. If this package isn't installed (though it should be, as it comes preinstalled with Ubuntu), then run sudo apt-get install network-manager
  • Note down the range of IP addresses you'll be able to use. Use the command ip addr to find out your machine's current IP address. This tutorial assumes that your network adapter is called enp0s3. If it isn't, then look for the correct one and also change the interface names in the subsequent commands. In the above example, we have an inet of 10.0.2.15, with the /24 denoting that the network uses a 255.255.255.0 subnet mask. In most cases, your usable network range will be whatever is in the first three places of the internal IP address, and then any unused number on your network between 1 and 255 in the last section. For example, we can use 10.0.2.16. If you're unsure, you can enter the subnet mask and your internal IP address into this website to calculate the usable range.
  • Note the IP address of your default gateway with the command ip r. In our example, it's 10.2.2.2.
  • Next, we'll add a new static connection option. Run the following command, making sure to change the numbers after "ip4" and "gw4" depending on your network conditions. These are the IP address you want to change your machine to and the current default gateway, respectively. sudo nmcli con add con-name "static" ifname enp0s3 type ethernet ip4 10.0.2.13/24 gw4 10.0.2.2 In our case, we do the following.
  • Set your DNS, manual DHCP (so, a static IP), and enable the connection. You can do that by running the following commands in succession. nmcli con mod "static" ipv4.dns "1.1.1.1,8.8.8.8" You can swap out the DNS servers above for whatever you want, they are in order of primary and secondary. nmcli con mod "static" ipv4.method manual; nmcli con up "static" ifname enp0s3 Once done, you can run nmcli con show to see if the new connection is enabled. If the output above looks like yours, then you're ready to go!
