The Jetson Nano is a robust and versatile embedded laptop that’s very best for a variety of functions, from robotics to synthetic intelligence. One of many nice options of the Jetson Nano is its capability to create a Wi-Fi hotspot, which can be utilized to attach different units to the Web or to share information. Organising a hotspot on the Jetson Nano is a comparatively easy course of, and it may be performed in just some minutes.

To get began, you will have to attach the Jetson Nano to a monitor and keyboard. After you have performed this, you’ll be able to open a terminal window and enter the next instructions:

sudo apt-get replace
sudo apt-get set up hostapd dnsmasq

These instructions will set up the required software program to create a hotspot. As soon as the set up is full, you’ll be able to create a configuration file for the hotspot. To do that, open the next file in a textual content editor:

/and so forth/hostapd/hostapd.conf

Within the configuration file, you will have so as to add the next traces:

interface=wlan0
driver=nl80211
ssid=MyHotspot
channel=6
hw_mode=g
wpa_passphrase=mypassword
wpa=2
wpa_key_mgmt=WPA-PSK

After you have saved the configuration file, you can begin the hotspot by coming into the next command:

sudo service hostapd begin

The hotspot will now be lively. You possibly can connect with the hotspot from different units by utilizing the SSID and password that you simply specified within the configuration file.
