    @aquapro Hmmmm
    The chip on your looks like a blob more than this; You might have gotten a chinese ripoff .. I dont remember the chip name... Hmmmm hard to see!

      @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           IRQ
      

      These 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...

      @Yveaux yes I checked wiring with (http://www.mysensors.org/build/connect_radio)
      more detail picture, hope so. (bad light)

        Pin 8?

          It looked like you could have a connection to pin 8, but apparently (in the better pictures) you haven't...

            @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/nRF24L01

            So the specs on that chip may be different. Maybe CE is inverted?

              hm ... if CE inverted, ping sample should not work?! CE must switch between hight and low for TX and RX right? But Ping sample send and receive works.

                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.

                  I hope you didn't get the left one when purchasing through the links in the MySensors "store"?

                      The left one works with MySensor-Coding, but only with disconnected CE line.

                        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?

                          I still see no difference when CE is disconnected.Only it as work at all.

                            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?
