Setting up a Wireless Access Point

It is convenient to setup a wireless access point on the Jetson Nano for the NAO robot to connect to automatically. This also allows the Jetson Nano to share internet access with the robot if it is connected to another network with internet access. The following instructions show how to setup an access point to host a local WiFi network using the Network Manager CLI.

1. Open a new Terminal window.

2. Add the wireless access point as a new connection by running the following command:

Replace <wireless-interface> with the wireless network interface (e.g. wlan0, wlan1, wlan2, etc.)

nmcli con add type wifi ifname <wireless-interface> mode ap con-name nano-ap ssid NaoNano

3. Set the 802.11 wireless band:

nmcli con modify nano-ap 802-11-wireless.band bg

4. Set the 802.11 wireless channel:

nmcli con modify nano-ap 802-11-wireless.channel 1

5. Set the 802.11 wireless security to use WPA:

nmcli con modify nano-ap 802-11-wireless-security.key-mgmt wpa-psk

6. Set the WPA password (this will be the password to connect to the WiFi network)

nmcli con modify nano-ap 802-11-wireless-security.psk <your-password>

7. Allow IP sharing so connected devices can access the internet:

nmcli con modify nano-ap ipv4.method shared

8. Start the WiFi network (Note: this can also be done from the networks menu):

nmcli con up nano-ap
