nrf52832 idle current is not 2uA

[Marshed]

I have programmed my device with ble_app_rscs available on nRF5_SDK_15.3.0_59ac345. I was expecting it the main loop 

for (;;)
    {
        idle_state_handle();
    }

the device will only consume 2 uA however it is consuming  8 uA. Can you assist me on why is that the case? is there something I am not switching off?

Hi,

The sleep current will depend on which modules/resources are enabled in your application. Have you modified anything in the example, or are you testing it directly from the SDK?

Have you disabled the softdevice and all running libraries/modules before entering sleep? Typical modules that are enabled is the NRF_LOG module, application timer, etc. If the softdevice is enabled, you can find expected current consumption for different configurations through our Online Power Profiler for BLE

Best regards,
Jørgen

Have you checked that these parameters are actually accepted by the peripheral? I tested this with the ble_app_rscs_c example in SDK 15.3.0, and I'm seeing ~11uA average current, but also BLE events occur every 1 second. This would explain the increased current consumption.
