Wake up from system on mode from an interrupt

[Prayam]

hello

i have 2 questions about System on mode: 

i testing different types of power comsuption modes, i've tested RTC wake-up for system on mode, but i want to try to wake-up from a button even if system off are in deeper sleep mode. It is possible to do? 

in BLE advertising , what is happening with the power comsuption? i read in the manual that system ON is the default state after power-on reset. therefore i believe that even that  send the advertising it enter in low power sub mode until the end of the interval. it's really like that? i'm trying to control this sequent with a RTC, interval 100 ms and duration 0  for the advertising, and it is ok, but i really want to know if there are better alternative to control power comsumption with BLE advertising, i see in the infocenter page that exist Advertising modes with a Slow mode, is that mode better that controling with a RTC? is that very different for coded_phy advertising?

thanks!

Hi!, 

testing more, it is posible to sending advertising in the sleep mode off System on? i put one bsp_board_led_invert after nrf_pwr_mgmt_run and  it is only do it twice unless it still advertising, when wake up from system on sleep state, the program dont restart and its continue with the next instruccion after nrf_pwr_mgmt_run? consider iám testing all with ble_app_beacon example.

Thanks again!
