soft device:s132
sdk:15.3.0
I implemented the following, but the event does not occur even if the voltage is V2.8 or less.
Do you know the reason?
===
NRF_SDH_SOC_OBSERVER(m_soc_observer, 0, pof_evt_dispatch, NULL);
void pof_evt_dispatch(uint32_t sys_evt, void * p_context)
{
if (sys_evt == NRF_EVT_POWER_FAILURE_WARNING)
{
sd_nvic_SystemReset();
}
}
static void power_pof_init(void)
{
ret_code_t err_code = sd_power_dcdc_mode_set(NRF_POWER_DCDC_ENABLE);
APP_ERROR_CHECK(err_code);
err_code = sd_power_pof_enable(1);
APP_ERROR_CHECK(err_code);
err_code = sd_power_pof_threshold_set(NRF_POWER_THRESHOLD_V28);
APP_ERROR_CHECK(err_code);
}
