I want to learn and play with LoRa. It's a 'IoT' technology that allows you to communicate over long distances using amateur (unlicensed) radio bands. Some of my friends have achieved distances of over 40km, and I'm curious to see what I can do with it.

So far I've been able to get a ping between two modules over a 10m range. Next up I'd like to transmit some useful data over longer distances (temperature for example), and then move on to devices that provide useful data (eg when a train passes a certain point to see if it's on time).
