Auto Access Point

This script is intended for the Raspeberry Pi. It will automatically create a hotspot, based on the given conf file. It will use systemd-networkd, wpa_supplicant and wpa_cli. The hotspot will be purely local, no internet connection.

[Not Tested] Check if ethernet connectivity also works

You need to have a wpa_supplicant-device.conf file similiar to this.

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                                                               
}

After having installed the script (see below) you can start a hotspot manually by running auto-hotspot

If connecting to the RPi by ethernet cable, you can set your computer to DHCP and work with link-local adressing, reaching the RPi by its hostname.
