Putting bl654 in sleep mode

[dkj047]

Hi all

How to put BL654 in deep sleep mode and standby doze mode using nordic nrf52840 ?? Also how to turn the system off?? 

Thanks

Hi 

I do have idle_state_handle() in my application

static void idle_state_handle(void)
{

  if (NRF_LOG_PROCESS() == false)
  {
    nrf_pwr_mgmt_run();
  }
}

Hi

Can you try replacing the sd_app_evt_wait(); call with a call to idle_state_handle() instead, as that should prepare the chip and set it to sleep properly?

Best regards,

Hi 

I have replaced the sd_app_evt_wait() with idle_state_handle () but the current consumption I am getting is still 1.7mA

Hi

If you still have the logging showing you NRF_SUCCESS or not after the idle_state_handle() call the chip will wake up right away and enable the logging module, which will cause an additional current draw. Try making the loop just contain idle_state_handle();.

Best regards,

Hi thanks

Do I really have to remove the logger in order to put the chip to sleep mode?? Is there a way to clear the logger for certain period of time so the chip will go to sleep properly??
