Looks good - I'm interested in LoRaWAN but wasn't sure how to start - this is a great intro.
One question on mind as I read it. How do you know if you are in range of gateway? Can you ping them or something or do you just send and not assume message sent unless you get OK return? I guess you could send two messages, the first a test/ping, and if get OK then send real data?
