I have a number of sensors.
I want them to send their data to my raspberry pi.
My idea was:
Make raspberry pi act as Wifi Hotspot (even though it isn't connect to the internet or anything. It just acts as a hotspot).
Run a UDP server.
- Configure sensors to connect to the SSID of the raspberry pi, and send data packets to the UDP server hosted on the PI.
I want to do this without using any external router or the internet. Can someone point me in the right direction?
