System OFF mode(0.3uA) in nrf52832

[Autobot]

Hello everyone,

I trying my nrf52832 getting ultra low power current conception mode using System OFF mode(0.3uA). I using SDK 15.2 ble_app_beacon example I change 32KHZ internal RC configuration this link and sd_power_system_off();  this command for low power conception but my module(PCA10040) take 5mA current for advertising. I need get ultra low power conception for sleep and advertising both side please share any example code or refer link to achieve this concept.

DK:PCA10040

SDK:15.2

Hi

Since you're using a module without the external LF crystal, you'll have to modify the LF clock configs in the sdk_config.h file to use the internal RC oscillator as described here.

Best regards,
