Gateway doesn't receive any message from node

[yury]

pinout looks ok.

btw This line from the Node log

1269 !TSF:MSG:SEND,100-100-0-0,s=255,c=3,t=24,pt=1,l=1,sg=0,ft=0,st=NACK:1

Means node cannot send OR gateway cannot receive. may be node radio is HCW somehow?
mysensors lib not broken\timeouts not tweaked?

@yury may be node radio is HCW somehow? no, it is not.

I'll try to create a new board and give feedback.

Update: it seems the problem was the DC-DC convertor. I have replace it with an extwrnal power source and now it works.
I still don't understand what was wrong there because the voltage on the radio module was correct:3.3V

@ctodor nice work!

When you checked the voltage, did you use a multimeter or an oscilloscope? If you used a multimeter, maybe there was a ripple or something that wasn’t visible.
