Raspberry pie 】 【 without WIFI even under the condition of the computer screen

I. Background

I want to connect the Raspberry Pi via WIFI without extra display.

Second, create a WIFI configuration file on the BOOT disk

File name: wpa_supplicant.conf.After the Raspberry Pi starts, it will automatically read this file to configure WIFI related.

country=CNctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdevupdate_config=1network={ssid="wifi name"psk="wifi password"key_mgmt=WPA-PSKpriority=1}

Third, start the ssh service

In the absence of a monitor, start the ssh service by creating a new empty file (named "ssh").

Fourth, connect through putty

If it is a hotspot opened by the mobile phone, when two connected devices can be viewed on the mobile phone, it means that both the Raspberry Pi and the computer are successfully connected.

Download putty online, and use the same WIFI connection as the Raspberry Pi after installation.The default hostname is "raspberrypi.local".

When you log in with the default username and password,You will find that the login is unsuccessful, and it will prompt "Access deny", that is because your Raspberry Pi system may be relatively new. At the beginning of the release in April 2022, you need to use the official burning tool to burn, and at the same time when burningAt the same time you can username and password.

V. Official burning tool burning system

download link, download the release directly.

Open after installation, support SD card formatting, andSelect the system type. If there is a downloaded system locally, you can also refer to it.

After selecting the system, select SD, and finally setIt configures the host name, user name and WIFI and language related.

Six, use putty to connect again

Because of system reasons, it is necessary to configure the user name and password to support WIFI connection login before burning. Now try to log in with putty again according to the configuration just now.

Click open, you can see:

Enter the username and password when you just burned the system, you can seeLogin successful:

In addition, using SecureCRT to log in is also an option for many partners.

VII. Summary

After the above operations, we can use the least hardware resources to control our Raspberry Pi.
