This script is intended for the Raspeberry Pi. It will automatically create a hotspot, if there is no known wifi nearby.
Therefore it will use systemd-networkd, wpa_supplicant and wpa_cli.
If no device is connected to the hotspot for a while it will search for neworks again.
You need to have a wpa_supplicant-device.conf file similiar to this.
country=FR
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
ap_scan=1
### auto hotspot ### # has to be the first network section!
network={
priority=0 # Lowest priority, so wpa_supplicant prefers the other networks below
ssid="autohotspot" # your access point's name
mode=2
key_mgmt=WPA-PSK
psk="passphrase" # your access point's password
frequency=2462
}
### your network(s) ###
network={
ssid="yourWifi"
psk="passphrase"
}
After having installed the script (see below) you can start a hotspot manually by running auto-hotspot --start-ap
and stop it with --stop-ap.
If there is a wired network connection the Pi will work as a repeater
How it works is also discussed here: https://raspberrypi.stackexchange.com/questions/100195
