I'm looking into using wireless communication for a project I'm working on, but I'm not sure where to start. I need to transmit small amounts of data from one device to another (back and forth) and that's really it. It's basically just a couple integers.
I'm familiar with your basic networking protocols but I'm honestly not sure what level to work on. Can I just buy a chip that I send my values that creates the ICMP packets and sends them off? I've looked online for some tutorials but I don't think I really know what I'm searching for so it's difficult.
Edit: This device doesn't need to connect to an existing wireless network - just needs to connect to another device and have a decent range.
Thanks!
