Do you have different radios to try with?

[Fabien]

yes with 5 radios and 1 amplified version !

[tbowmo]

are those 5 radios from the same batch?

have you seen this forum thread

Might be cheap NRF24 clones you've got..

[Fabien]

Ok so where can I buy good nrf ?
Actually all my componment and modules comes from electrodragon without any problem.

Ok I try now with only few centimeters and PA_LOW on gateway and it doesn't work well....

[Fabien]

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.

I bought the latest batch of NRF modules from itead, together with my sensebender pcb's. It should be genuine NRF chips they use.

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 !
