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?

A while loop like 'while(1);' consumes about 6mA but 'while(1) { __WFE(); }' consumes less than 10uA.  I suggest first to test that without any thing else.  If you don't get a similar result, then there must be a hardware leakage somewhere.  Enable UART will consumes about 300-500uA.

The power_manage() will return immediately if there is a pending application interrupt not handled.
