Thanks for your lmic_slim feedback.
In short: My feeling is not really because:
- I’m almost certain that lmic_slim is not LoRaWAN compliant because there is no indication of that whatsoever. It is not even clear what is and what is not supported by the library.
- The library is provided as a ZIP file and you ask for feedback via email.
That is not how open source development works.
- What should people give feedback about when nothing is even documented?
That depends on your definition of ‘better’.
While 8-bit AVR MCU’s are still used there is a tendency to shift to 32-bit ARM MCU’s (and things like ESP32) that have (much) more available memory resources, are more powerful and are better able to handle a full LoRaWAN stack implementation.
Multiple LMIC libraries are available for the Arduino framework already. They will not be as small as lmic_slim but are LoRaWAN compliant, are open source and (some) are well-maintained.
In answer to “would it be worth to you to get the lmic_slim to a better level”, I guess not, unless you want to develop for a niche, have much spare time and are willing to maintain it for longer time.
