nRF52840 uses ble_app_hrs_freertos demo, unable to enter low power consumption

[Jinl]

Hi,
I run ble_app_hrs freertos on PCA10056 DK board and cannot enter low power consumption. 
Do I need special settings to use freertos to enter low power consumption?

The following are my test conditions:
1. Use SDK17\examples\ble_peripheral\ble_app_hrs_freertos example.
2. Comment out timers_init(); and buttons_leds_init(&erase_bonds);
3. Compile the routine and burn it into PCA10056 DK.
4. Use a current measuring instrument to test the current waveform as follows

Hi,

I have a few questions. How do you measure the current consumption? Do you measure on the nRF current measurement port so that you isolate current consumption from the interface MCU etc? See Measuring current for details.

Also, have you disabled UART logging by setting NRF_LOG_ENABLED to 0 in sdk_config.h?
