It took all of (maybe?) an hour to setup 2 Adafruit Feather M0 with RFM95 LoRa Radio devices and have them ping each other using the simple getting started guide and default code.
One device is sitting on my desk in my office, the other is in the barn. What's amazing is the two are separated by about 80m (~260'), my office is in the basement (underground), my basement walls are roughly 17" thick stone/concrete, and both the barn and the house have metal roofs.
The device in the barn is in a weatherproof enclosure, and is running off a 1000mAh LiPo battery. Both devices have 3" wire antennas.
