Hi
Now everything works fine. Just one laste thing. I am using connection led but it will not shut off.
If the board is advertising and you shut the board in deepsleep the light stays on.
digitalWrite(XX, HIGH); dos not work.
Bluefruit.Advertising.stop(); no effect on the light.
void enter_deep_sleep() {
// Print a message before entering deep sleep
Serial.println("Entering deep sleep...");
pinMode(BUTTON_PIN, INPUT_PULLDOWN_SENSE); // Set the pin to pull-down and sense high level
nrf_gpio_cfg_sense_input(BUTTON_PIN, NRF_GPIO_PIN_PULLDOWN, NRF_GPIO_PIN_SENSE_HIGH);
delay(500);
Serial.println("Qspif");
Bluefruit.Advertising.stop(); // Stop advertising
delay(100);
Serial.end();
QSPIF_sleep();
// Enter deep sleep mode
//NRF_POWER->SYSTEMOFF=1;
sd_power_system_off();
}
It is not the lowest consumption if the led stays on.
edit:
Bluefruit.autoConnLed(true);
Bluefruit.autoConnLed(false);
found it
