I found after a while I can't scan BLE device "ANCS2". Since I don't implement wake up mechanism, how to prevent nRF52832 device to enter sleep mode?

Hi,
Are you using nRF Connect SDK or nRF5SDK?
Can you share your code?

Jared

Hi,
In BLE_ADV_EVT_IDLE you call sd_system_off() by _sleepModeEnter(). The program will enter BLE_ADV_EVT_IDLE after advertising has ended. If you want to avoid the program going to system off sleep then remove the function call from the BLE_ADV_EVT_IDLE event.
Thanks for your suggestion! I have removed calling _sleepModeEnter(). But nRF Connect still can't scan BLE device "ANCS2" after _advertisingEvtHandler() handles BLE_ADV_EVT_IDLE event.
The following is log messages of nRF52832 device:

I have removed calling _sleepModeEnter() and calling advertisingStart() when _advertisingEvtHandler() handles BLE_ADV_EVT_IDLE event. Do you think it is good idea?

Hi,
Are you able to find the device advertising if you remove the filter?
snowuyl said:I have removed calling _sleepModeEnter() and calling advertisingStart() when _advertisingEvtHandler() handles BLE_ADV_EVT_IDLE event. Do you think it is good idea?
Yes, this is fine. The advertising module will go to IDLE state after it has iterated through all the enabled advertising states and no connection requests has been received. Restarting advertising when it has reached the IDLE state is ok.
Are you using a custom board or the development kit?

Jared
Thanks for your reply!
