I want to setup a headless Raspberry 3 A+ (no ethernet) as a WiFi hotspot.
The device runs its own web server and application, it should not necessarily provide internet access when connected to the hotspot.
It has two wireless adpters, the internal one and a RTL8188EUS Wireless adapter plugged in the USB port.
The goal is to use the device off-grid as a web server for a dedicated application.
The HotSpot should use the external USB adapter, since I use the internal one for SSH when connected to my local WiFi network.
How do I configure the external adapter as a hotspot manually? The dietpi script unfortunately requires an ethernet connection but the A+ does not have one.
Yes, unfortunately a limitation of our install script. Theoretically you could do this with 2 WiFi adapter, but you would need to configure everything manually. You could use our install steps as idea how it could be. You just need to replace interface names with yours.
