Hi all,
I am using power profiler kit to measure as mentioned below screenshot.
I want to achieve current number as mentioned in Nordic product specification as" IOFF_RAMOFF_RESET System OFF, no RAM retention, wake on reset 0.40 μA"
I think I must do these for low power and modified code add DCDC function, set noram retention, set lfclock. I modified the code in ble_power_profiling as follows:
---------------------------------------------------------------------------------------------------------
power_management_init();
ble_stack_init();
sd_power_dcdc_mode_set(NRF_POWER_DCDC_ENABLE);
if (!m_is_notification_mode && !m_is_non_connectable_mode)
{
// The startup was not because of button presses. This is the first start.
// Go into System-Off mode. Button presses will wake the chip up.
nrf_pwr_mgmt_shutdown(NRF_PWR_MGMT_SHUTDOWN_GOTO_SYSOFF);
}
------------------------------------------------------------------------------------------------------------
I am not achieving the number in spec. So please suggest me what I am missing.
Thanks,
Sridhar
