Try to run basic example of TimedWakeup.h , from examples library ArduinoLowPower librairie and get this:

It's look like a library is missing, but I don't have a clue wich one....

RESULTS:

Hi @lucharbour. The only nRF52-based board supported by the "ArduinoLowPower" library is the retired "Arduino Primo. This error is expected when you attempt to use the library when compiling for any other nRF52-based board:

So you should look for another solution for implementing low power code in your Arduino sketches. You can start by searching the Arduino IDE Library Manager to see if a 3rd party library is available with the desired capabilities.

Thank you for your help.
I do indeed tried multiple librairies.
the one that seem to work best is

include <Arduino_nRF5x_lowPower.h>

I don' have compilation error with that one. But I still cannot make the program work....
All seem to run correctly exept when I expect the system to stop, or sleep, Meanning after the command
sd_app_evt_wait();

The program keep on running as it this line does'nt exist..

Any update?

Seeed have a support forum for their product;

nothing about that work. I really think that it has to do with some flag left On by other process. I need to find a way to clear all pending flag from any process but I struggle to find them all. I try to limit all application but even if I try a basic program that do nothing but going into sleep, it look like there is many ghost process in background.
