I found the problem. It was the 3.3 V from the arduino uno. Its seems ok with a voltmeter but is not so stable for the nrf

the serial says :
100: 0;0;3;0;9;gateway started, id=0, parent=0, distance=0
0;0;3;0;14;Gateway startup complete.

I have reset lots of time, even reset eeprom.. nothing has changed..

Hello,
I m wondering a lot of questions for several days

I'm using my configuration for 6 months and all is ok
my three sensors came out of energy in the same time
after fews days, i change the battery and they work again
However, my serial gateway (with arduino uno) don't receive anything.

I test all the things (capacitor, energy...), all is ok
I upload the arduino with a sensor build. It works good and sends / receives data
I tried the nrf with another arduino, the gateway finds my sensors

I don't understand how it is possible...

please help...
