question about tutorial Wireless timer synchronization among nRF5 devices

hello ,  I followed this tutorial : devzone.nordicsemi.com/.../wireless-timer-synchronization-among-nrf5-devices

when i put the button 1 i have just a signal of 2 second on my oscilloscope and the signal aren't synchronize.

I can't figure it out how it works,  I can't test if met timer are synchronized.

if someone can help me thank lot .

  • when i put the button 1 i have just a signal of 2 second on my oscilloscope and the signal aren't synchronize.

    We need more information, I have not idea what you are talking about. 

  • I explained myself a little more clearly I followed the tutorial and I took the code to get an example of synchronization on two peripheral cards.
    I did the test by pressing button 1 on one of the two cards but I only have a two second signal on the status of the gpio and the signals are not synchronized, and besides I don't fully understand the code even after full proofreading.

    sometimes I have this : 

    and sometimes I have this : 

    I have a different result all the time and I would like to get to this one: 

    and in the tuto you can do long tests but I don't see how to do this anymore, since after 2 seconds after pressing the button I don't have any more gpio signal.
