Change the access point settings
Modify the hostapd.conf configuration file by typing:
sudo nano /etc/hostapd/hostapd.conf
An editor interface should appear.
Modify the ssid and wpa_passphrase fields.
ssid corresponds to the wireless network name (default: LeoRover-XXXX) and wpa_passphrase is the network password (default: password).
This may be useful if you notice the network interference in crowded areas or you want to use multiple Leo Rovers at once.
Modify the channel field.
channelcorresponds to the Rover 2.4 GHz Wifi access point broadcast channel. You can choose from 1 to 11.
Modify the country_code field.
Set to indicate country in which the device is operating (regulatory domain). The country codes follow the ISO 3166-1 standard.
This can limit the number of available channels to use.
Type Ctrl+O and Enter to save the modified configuration and Ctrl+X to exit the editor.
In order to apply the modifications, you need to restart the access point daemon. To do so, just type:
sudo systemctl restart hostapd
