I love LoRa it's was one of my first large embedded project because most oss LoRa software (especially firmware) is poorly implemented/maintained. It ended up leading me to rewrite the BMC SPI driver for rasbian to finish the //TODO section and the other comment saying //Untested, might work... in prod

That said, lora is great, it's just very low bandwidth and high overhead, which is by design, but you can't really implement a working network stack and get good distance. I think the fastest I could transmit with "full duplex" enabled was like 2kb/sec at like 2000ft iirc. I ended up just coming up with a scheme to negotiate send/receive times so each radio could properly operate in full duplex mode. 

That and radiohead software just wouldn't compile I ended up rewriting it all. I guess some people have figured out how to operate the lora protocol with better radios and tech stacks, but it's a pretty big limitation considering we have FSK and OSK? radios with much better performance on much older and powerful technology?
