Do yourself a favor and look up Ben Eater on Youtube.. Ben has a series of videos explaining computers starting at the digital logic gates and builds a complete but minimalistic microprocessor out of simple logic chips, and then walks through writing a small program (the computer only has a few bytes of RAM!) https://www.youtube.com/playlist?list=PLowKtXNTBypGqImE405J2565dvjafglHU Then, he also has another series that expands upon this and uses 80's era parts which are still available to build a simple computer with more capability. https://www.youtube.com/playlist?list=PLowKtXNTBypFbtuVMUVXNR0z1mu7dp7eH Best of all, he sells kits that you can get to "play along" and build with him. The videos are amazing for a beginner or an experienced viewer. I've been a computer geek since the very early 80s and yet I really had no idea what the "microcode" in a CPU did until watching these videos. He explains things so well!
@BearWithBeard I found my problem. It turns out my arduino had a false contact on one of the ground pins I was using to power my radio. When I noticed, I resoldered the header pin on the nano and it magically started working. It works with both the normal and the long range antenna and I do see a big difference in range. Thanks for all the help again. Guess I will have some spare radios now...
Yes in the mean time I understand that MySensor have all the personalized ask/answer structure.
But I still study cause I like much this type of home network.
Anyway maybe there can be a personalized gateway part only for the incompatible sensors.
I'll try to study it when I'll be more "old" in this
Thanks a lot for the answer
Yes, no real EERPOM, but emulation in flash. EEPROM failure was the first finding when checking for this error message. Maybe somthing else...
Now complete sketch is ported from AVR ProMini to STM32 and is runnig fine
I have created a Node-Red Dashboard that can be used to manage the wireless network and display sensor data. No programming is involved when using the available sub-flows and sketches. New devices can be added by creating new Subflows.
This is designed for users who want to create their own devices. Example: create temperature and soil moisture sensors to monitor their plants.

hello thanks for the reply ...

What do you suggest me?
I suggest that you start reading and learning on this site and then begin building.
We don't know the ranges between nodes and gateway nor what sort of data you want to send, so learning what mysensors is and what it can do for you is the only option.
@andrezibaia LoRa has by far the biggest link budget, so if it can't manage it, probably nothing else can either, assuming similar transmit power.
Also, you may find that your best signal path isn't straight through 5 floors of reinforced concrete but rather bouncing the signal off an adjacent building or the like.
