Really nice, did you buy the glass plates from there ?

If not, can you please tell where you get them from ? Thank you !
For those of you who want an extremely simple build, I've reduced it to just 5 parts:
one 1-megaohm resistor (0805 SMD)
one Arduino Pro Mini
one Ra-01 LoRa module
Male header pins
Battery clips
See photos.
Ok, finally it's solved. I installed everything from scratch. Then installed your sandeep lib from your github. And finally added the LEDs and Buttons to the variants.h. That compiled successfully. And my problem was that the sensor is sleeping and I couldn'T get a heartbeat answered.
So everything is clear and now testing...
