create hotspot #92

Closed jscancella closed 1 year ago

jscancella commented 1 year ago

Is there an officially supported way to create a hotspot on the CB1 image? I tried following https://www.raspberryconnect.com/projects/65-raspberrypi-hotspot-accesspoints/157-raspberry-pi-auto-wifi-hotspot-switch-internet but it just fails to stay connected and goes into an endless loop trying to connect.

I tried to follow https://computingforgeeks.com/create-wi-fi-hotspot-on-linux/ which should work since you are using networkmanager for the wifi, but as you can see below I am getting an error when it tries to bring the wifi hotspot up. This is using the https://github.com/bigtreetech/CB1/releases/tag/V2.3.0 minimal image.

yeah, i have the exact same iusse

mmuellerphoto commented 1 year ago

Same here! Would be very helpful to have a hotspot.

Flavourdynamics commented 1 year ago

This would be great.

jscancella commented 1 year ago

For people looking for an answer in the future, https://github.com/oblique/create_ap seems to work

kieraneglin commented 1 year ago

@jscancella what command did you use to get this running and what is your use case? I want my CB1 to act as a wifi AP without internet sharing but I keep getting "Your adapter can not be a station" errors

jscancella commented 1 year ago

@kieraneglin using it for Rat-OS. It is used to setup the system on first boot when it isn't connected to the local wifi yet. I was talking with a BTT tech and they said to use create_ap which worked

kieraneglin commented 1 year ago

@jscancella thank you! That helps a lot. Is there any chance you remember what command you are issuing on startup?

jscancella commented 1 year ago

I changed the config file https://github.com/Rat-OS/RatOS/blob/v2.x/src/modules/hotspot_cb1/filesystem/root/etc/create_ap.conf And then ran sudo systemctl enable create_ap See the whole install script here: https://github.com/Rat-OS/RatOS/blob/v2.x/src/modules/hotspot_cb1/start_chroot_script
