CE line on sensor node?

@aquapro The MySensors site (http://www.mysensors.org/build/connect_radio) gives the following wiring:
Arduino nRF24 9 CE 10 CSN 13 SCK 11 MOSI 12 MISO 2 IRQThese are the defaults for the library. CE & CSN you can adapt through the constructor of MySensor (did you do that?)
Looking at the pictures I have a hard time figuring out the connections for pins 8..12, while these are just the interesting part...

Pin 8?

@aquapro I dont think you got a nordic semiconductor nrf24l01, What I can find they are only in QFN package.
http://www.nordicsemi.com/eng/Products/2.4GHz-RF/nRF24L01So the specs on that chip may be different. Maybe CE is inverted?

Hi,
I have bought the new modules (right on pic), which operate without modification. I simply swapped and all is fine.
What do I do with the other. How can I test inverted.
-
If it truly works correctly with CE disconnected, that could be an advantage when there is a shortage of pins (eg: 8 pin ATTiny).
Have you achieved full operation without CE on the old modules?
And did you leave CE floating or tie it high?
-
What vendor did you use to get the "no CE needed" variants? That could be useful to test.
I'm assuming that the nRF24L01+ doesn't work without CE connected, right?
