In this previous post I described how to discover Netduinos on your network without knowing their IP’s. Building on that, this post describes how to make a Netduino log temperature data, and then how to build a Universal Windows 10 app that displays that data.
With the advent of Internet-of-Things things, you’ll probably need a decent way to actually find all of the things on your network.
Fun fact: If you send a UDP packet to *.255 on your network, your router will then send that along to all the devices on your network. So if your local network is on 192.168.1.x, then send it to 192.168.1.255. Or if you want to send it to everything, then you can send to 255.255.255.255.
In my case, I’ve got this awesome little guy…
…setup with DHCP, so the IP occasionally changes. I’ve got a Windows 10 app that needs to connect to it, so we can use the way above to find the Netduino on the network.
