I have a number of sensors.

I want them to send their data to my raspberry pi.

My idea was:

  1. Make raspberry pi act as Wifi Hotspot (even though it isn't connect to the internet or anything. It just acts as a hotspot).

  2. Run a UDP server.

  3. 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?

I am an experienced programmer with C++, Java, Javascript, Python etc, but I'm new to raspberry pi.
