Sleep mode power consumption

[fgeldenh]

I would like to confirm that my hardware design is correct and in addition that I am following the correct procedure to place the nRF52832 to sleep to achieve the lowest possible sleep current. I am using the standard unmodified power management example for PCA100040. Although I only have a single button, it should still work as I understand. I am using Segger Embedded Studio with j-Link. I understand that in order to run the sample I must not run in debug mode. I am still however getting a current draw of 850uA. As you can see, I am using the module from Raytac.

Edvin - Thank you for your prompt response.

I am using the very simple peripheral (nrf_pwr_mgmt_pca10040) sample code. I attach two files, the one is using ublox EVK-NINA-B1 kit which is pretty similar to the nRF52 DK, and the other is my custom board.

These files depict the output from the sample code. In the case of Ublox it works as expected whilst my board does not shut down. I sent the schematic so you can look and see why there may be different behaviour.

The Ublox kit has a built in Segger debugger while in my case I am using the Segger J-Link debugger.

Maybe you can help me find out what the difference may be.

Thank You
