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?

Hi,

It is a bit difficult to know exactly what is the problem here. The chip will typically not be able to enter low power mode if there are pending interrupt that are not handled or peripherals that are enabled and active. So I guess my suggestion for debugging is to try to disable peripherals or stop serial tasks before trying to enter sleep.

Best regards,
Kenneth
