Hey, I’m having a heck of a time. I want to write a Kotlin command line app (for Linux) that makes a machine with a wifi card into a wifi direct group owner, then listens on a particular port on the wifi direct interface for incoming socket connections. Does anyone have a non-Android example in Kotlin or Java that makes a machine a wifi direct group owner then uses ServerSocket or similar to listen on a particular port for wifi direct group members to connect to?

[Ed Brindley]

I think it would depend on what is being used to manage the configuration of the wifi interface (wpa_supplicant, network manager etc)

Let’s say we’re on a Raspberry Pi running Ubuntu. We’ve been toying with wpa_cli , but need a programmatic way to set this up. Would you suggest using the native libraries underlying wpa_cli ?

[Ed Brindley]

I think that is the approach I would take

[Ed Brindley]

Just had a quick look and there doesn't seem to be anything out there that does this already

[Matthew Adams]

Ok, we’ll start by just shelling out & calling wpa_cli to begin with, then look at calling from whatever we write our server in (JavaScript, Kotlin, etc) into the native library/libraries…. I’m getting the inkling that we may just be able to edit /etc/wpa_supplicant.conf programatically…
