@m26872: on my side I had no trouble with nrf. maybe lucky. but you are right because I don't use common stepup, nor eval boards or I make it for test. But, there are lot of cool low noise stepup.
I have not tested this, and I am very curious, I don't know if nrf/rfm range would be the same at 1.9v vs 3.3v ? btw, for range, I prefer to use rfm69 for my setup, so consumption is not the same! (my dream would be to use cc1310 but have no time to invest, I have not much time actually to play with my devices...)
But I see what you mean, simplicity too, I totally agree
