Try after disabling the log NRF_LOG_ENABLED to 0 in sdk_config.h file

When connect 5mA or idle mode? I think problem is your PCB design. You created PCB LDO or DC/DC mode?

Sorry, schematic I cannot give :( For now, my electrical engineer is measuring 5mA at the System Off.

Can you give me PCB shematic? I think your problem about hardware. And also can you measur current with blink led after measur current led off. Is there any different measurment?

I don't see any changes in current consumption with or without those lines :(

Thanks, I'll try it :)

int main(void)
{
    // Initialize.
    leds_init();
    timers_init();
    log_init();
    buttons_init();
    ble_stack_init();
    gap_params_init();
    gatt_init();
    services_init();
    advertising_init();
    conn_params_init();
    sd_power_dcdc_mode_set(NRF_POWER_DCDC_ENABLE);
    sd_ble_gap_tx_power_set(0);
    // Start execution.
    NRF_LOG_INFO("Program başladı.");
    advertising_start();

    // Enter main loop.
    for (;;)
    {
        if (NRF_LOG_PROCESS() == false)
        {
            power_manage();
        }
    }
}

you must placed in main.c

Sorry @omeracar, where is it should be placed? Before or after the ble initialization?

Is not dc/dc set automatically? What does enabling of the dc/dc converter?

Is setting of the tx power to the 0 will not affect to the ble transmit?

Thanks! 🙂

By the way put this code in main. For more effective current.

sd_power_dcdc_mode_set(NRF_POWER_DCDC_ENABLE);
sd_ble_gap_tx_power_set(0);

RE: The right way to enter to the system off mode

Michael — Tue, 03 Apr 2018 08:30:54 GMT

Yes :(

Did you see NRF_LOG_INFO("I'm not sleeping?")?

RE: The right way to enter to the system off mode

Michael — Tue, 03 Apr 2018 08:21:28 GMT

It's peace of the code:

while(nrf_gpio_pin_read(ON_SWITCH_N_PIN_INPUT) != switchOnDefaultState)
{
    //be in while until button is not released
    nrf_delay_ms(50);
}

//Wait while the main system will shutdown
nrf_delay_ms(6000);

//Power off the main system
SecureOnPinOff();
NRF_LOG_INFO("got close app from the main system, I'm going to sleep");
NRF_LOG_PROCESS();

NRF_LOG_INFO("-- Going to the DeepSleep");
NRF_LOG_PROCESS();

nrf_delay_ms(1000);

uint32_t res = sd_power_system_off();
NRF_LOG_INFO("I'm not sleeping!1");
NRF_LOG_PROCESS();
res = sd_power_system_off();
NRF_LOG_INFO("I'm not sleeping!2");
NRF_LOG_PROCESS();
res = sd_power_system_off();
NRF_LOG_INFO("I'm not sleeping!3");
NRF_LOG_PROCESS();

I need only main.c

RE: The right way to enter to the system off mode

Michael — Tue, 03 Apr 2018 08:03:38 GMT

Hello! I have more than 5000 rows of the code. When the main system is not working I'm putting the board to the system off. I think that I need to close another processes before the deep sleep, but not sure. What flags can be checked? What should be done? It's so not clear in the documentation... :(

When sd_power_system_off() your board monitoring app? Where adding sd_power_system_off() function in your code?
