Heltec LoRa V3 - Tech from Hell, and a Deal with the Devil

Regarding Long Range Wireless Communications, the Heltec LoRa V3 boards are a "deal with the devil" in terms of trading comfort and peace of mind with quirks and weirdnesses at a, however, pretty competitive price. Heltec changed in its WiFi LoRa32 v3 board the chips from its older SX1276/SX1278 to the newer SX1262 - and with that, introduced a whole new way of programming the device, from "polling" (i.e. "did I get a message and then do something", at your leisure) to "interrupt-driven" (i.e. "interrupt whatever was happening because of some message" and mostly driving people nuts). Now this is a change I deem unfortunate - and even more unfortunate I deem it that Amazon sellers are not really allowing you to give honest reviews, and that Amazon is letting them play along, arguing "community standards breaches" WITHOUT being able, when explicitly asked, to point out WHAT has said breach consisted in: apparently, insufficient praise is offending the majesty; and thus, I do so here. Things start with weird hardware choices - e.g. a display of dubious necessity, barely possible to solder without melting its connector - and continue into the outright stupid, as when you enable "Erase All Flash Before Sketch Upload" it nukes your microcontroller's "license" and you are getting a "Please provide a correct license" error (which, fortunately, can be fixed as demonstrated via the Hayes command AT+CDKEY from a serial connection). Still, I do show you some fun stuff, like e.g. controlling remotely your computer via a RS232 Serial-to-LoRa bridge. Code and advice: https://github.com/KedalionDaimon/Tec...
