    If I disconnect orange wire (red marker on first sensor picture), sensor works fine.

    @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...

      hello,
      very good project!
      I currently testing version 1.4b1 and I have a problem. Only if I disconnect the CE line on the sensor, the values ​​are transferred.
      If the CE line is connected, only one part will be sent, see Figure 1, the LED on the sensor remains on. As soon as I disconnect CE line, all values ​​are not sent are transmitted (Figure 2) and the LED goes out and lights up briefly in the next transmission.

      Does anyone have an idea?

      greeting

                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?
