How to Setup Raspberry Pi Headless – WiFi

The headless setup using WiFi makes easier to access your Pi than Ethernet setup. It needs an SD card and power supply only. It provides access to your laptop Keyboard, Mouse and Screen to your Raspberry Pi without the need for an external setup.

If you want to access the Pi using Ethernet check this tutorial.

Components Required:

Hardware:

Software:

Buy Raspberry Pi

Steps for Headless Raspberry Pi setup using WiFi:

Step 1:

Flash the Raspbian Image file using Win32 Disk Imager.

2.Pi with Laptop

Step 2: After flashing open SD Card and Create ‘wpa_supplicant.conf’ file and empty ‘ssh’ file.

3a. WPA and SSH after flash

Step 3: Now open ‘wpa_supplicant.conf’ file using any text editor and paste the following code.

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=GB

network={
ssid="SSID"
psk="password"
key_mgmt=WPA-PSK
}

Modify the “SSID” and “Password” with your WiFi Credentials.

Note: Make sure the “Double Quotes (“”)” are in default notepad fonts. If not sure delete and replace it by yourself manually. Use any text editors like notepad, notepad++ or Sublime Text.

Example:

SSID= "FactoryForward"

psk="PiFactory"

Sample Files for Easy Access:

I have attached those 2 files for easier way. Download those files copy and paste it into the SD Card (not inside any folders, paste in home itself).

Download Here

After the two files are placed, eject the SD Card and insert into the Raspberry Pi.

Set up a Portable Hotspot in your mobile phone with the Network Credentials below

SSID Name – FactoryForward

Password – PiFactory

Now Power ON the Raspberry Pi, wait for few seconds until it boots. In some mobiles you can see the number of devices connected to the Hotspot. If any device is connected then Raspberry Pi is booted successfully and connected to the WiFi.

Important Note: The Laptop and Raspberry Pi Should be connected to the Same WiFi Network (mobile hotspot in our case) for SSH.

Step 4: Wait for 30 seconds until Pi boots up and connects to your WiFi Network. Then open Advanced IP scanner software that you installed on your Laptop. Before that open command prompt and type ‘ipconfig’ to get your IP address range.

Here my router assigned is ‘192.168.43.1’. So the IP address ranges from 192.168.43.0 to 255. So in the search tab put your IP address and remove the last digit range from 0 to 255. See the image below.

Example: 192.168.43.0-255

Then click Scan. This will show up all the devices connected to the router in this range. You can Identify the Pi’s IP by the Manufacturer name. Note down the Pi’s IP address.

5.Advance IP Scanner Pi

 

Step 5: Now open putty and log in to Pi using Raspberry Pi IP address we found using Advanced IP Scanner. In my case, it is ‘192.168.43.164

6.SSH to Pi via Putty

Now the terminal window will open (Click yes on security warning) then enter Pi username and password. The default username and password is

Username: pi

Password: raspberry

 

Another Method without using IP Address:

In this method, you need to have Apple Bonjour service software on your computer. If you have iTunes, then Bonjour is installed already. If not, you can download and install it here.

What is Bonjour?

Bonjour is a print service plugin used to search printers on it’s network made by Apple. It is used to map the Pi’s IP address with a hostname called ‘raspberrypi.local’. You can use this on Putty and VNC Viewer instead of IP Address. This eliminates the IP address finding step here.

Step 6: After logging in type ‘sudo raspi-config’ and hit enter.

8.sudo raspi config

Step 7: In the GUI navigate to ‘Interfacing options’.

9a.raspi config GUI

Then navigate to ‘VNC’ and enable it. Click Finish and exit the wizard.

9b.Raspi GUI VNC

After finishing, type ‘vncserver‘ on the terminal window and hit enter.

Step 8: Now, Open Real VNC Software that you installed and type Pi’s IP address or hostname (if bonjour installed) then click enter.

Example: 192.168.43.164

or

raspberrypi.local

In some cases you might need to add a ‘:1’ at the end of IP or hostname.

Example: 192.168.43.164:1  (or)  raspberrypi.local:1

10a.Real VNC Home Screen

Login with Pi username and password. The default username is ‘pi’ and password is ‘raspberry’.

10b.Real VNC Login Pi

Accept the security warning. Now the Pi Desktop window will show up. That’s it now you can access your pi over WiFi without cables. Just a power supply is enough.

    Thanks for the tutorial, very useful!

    Just a small FYI, there’s a typo just after step 3 where it says “wpa_supplicat.conf”. I copied and pasted this as my file name and got confused when it didn’t work. I added the ‘n’ to my filename and it is working now!

    Best regards, Norm

    while connecting the vnc server in raspberry OS, you have to type vncserver then wait for a while. It will display the vnc server details with ip:number. You have to give this info in the vnc viewer as ip:number otherwise it won’t connect to raspberry pi remote screen.
