How do you wake back up from sleep? I tried using nrf_gpio_cfg_sense_input() to no avail.
#include <Arduino.h>
#include <Wire.h>
#define wake_button 10
void setup()
{
Serial.begin(115200);
while(!Serial);
sd_power_mode_set(NRF_POWER_MODE_LOWPWR);
sd_power_dcdc_mode_set(NRF_POWER_DCDC_ENABLE);
__WFE();
__WFI();
sd_app_evt_wait() ; //SOFT DEVICE “SYSTEM ON” POWER SAVE
pinMode(wake_button, INPUT);
attachInterrupt(digitalPinToInterrupt(wake_button), ISR_WAKE, RISING);
}
void loop()
{
delay(10000);
nrf_gpio_cfg_sense_input(wake_button, NRF_GPIO_PIN_PULLDOWN, NRF_GPIO_PIN_SENSE_HIGH);
Serial.println("SLeeping");
delay(100);
NRF_POWER->SYSTEMOFF = 1;
}
void ISR_WAKE(){
}
