@Fabien, regarding the 'st:fail' . How are you powering UNO and Radio? Some very cheap phone chargers may introduce a lot of noise on power that even a big capacitor can not handle...
So i try with 2 AA battery for powering radio on gateway. Same about 50% of st:fail. Powering arduino from 2A power supply. At oscilliscope, using spectrum analyzer nothing to report on 3.3V and 5V. Pehaps dupont cable ?
Now I just try with another sensebender with radio directly solder on board and it work fine with no st:fail. radio was previously tested on the first board with lot of st:fail. I will chek the first board, perhaps bad solder or problem with adaptater.
ok for my next xenebender batch I will buy NRF together. And now I confirm the problem with bad contact (with my finger it works fine !!!. I will directly solder NRF to sensebernder tomorrow. Strange, my solders seems to be fine and I made it all one mmore time but same problem.
I will let the new sensbender online all the night. I will check tomorow my grafana input !
