I want to use a Raspberry Pi as an access point that is not linked to the internet. If I connected one other device to that access point, how could I connect a socket between this access point and the device connected to it.

If this is not possible with sockets, how else could I transfer data in this way?

  • The same way you would create any socket! – Milliways Dec 29 '18 at 22:20
  • That's what I would think, but the Raspberry Pi is not connected to any network. UNLESS, you can connect the Raspi to its OWN network. 🤔 – Andrew N. Dec 29 '18 at 22:31
  • can you ping the connected device? – jsotola Dec 30 '18 at 0:31
  • Are you asking two questions? How to configure an access point and then program a unix socket connection to it? Or do you have already a running access point? Please address me with @Ingo, otherwise I won't see your reply. – Ingo Sep 7 '19 at 8:49

You could use "pi-ap"- a Github repo which automates the configuration of a Pi into an AP- and unplug the uplink from your Pi from the router to ensure it can't route traffic to/from the Internet.


So you'd connect to the AP on the WLAN0 IP- the default for "pi-ap" is by joining the SSID you set for your "pi-ap" installation. Once you join the AP, you can SSH into it on that IP.

"pi-ap" should meet your requirements to create an AP with not Internet connectivity with minimal effort. Seriously, edit a few variables in variables.sh and then do sudo ./install.sh and you've got yourself an AP. HTH- Terrence
