nRF52832 consume current > 5mA

[sanghan]

Hello.

i setup - BLE Stack + Uart 1 + SPI 1.

Infinite loop inside nothing code.

nRF52832 consumed 5mA + a.

and i add power_manage() in Infinite loop.

Nevertheless nRF52832 consumed 5mA + a.

How do I reduce power consumption further?

Thank for Reply.

power_manage() inside called sd_app_evt_wait(). i disabled UART and SPI. current not reduce.

I found the cause of the problem. I used timer 1ms tick.

I solved my problem. i add code Infinite loop in __WFI(). Timer tick change 500ms and use wake up.

My nRF52832 consumed under 2mA.
