Based on the explanation of the article "Deep Sleep for WF121", I configured the RTC to trigger a event with a delay of 20 minutes.
Unfortunately the internal alarm of the RTC is triggered immediately as if the contents of the alarm register were not interpreted.
It is notable that the "repeat_mask" and "repeat_count" fields work correctly.
# set the RTC alarm will trigger an event after 20 minutes
Is this a known problem and is there a solution ?
call system_set_max_power_saving_state(0) call hardware_rtc_init(1,0) call hardware_rtc_set_time(2013,6,3,1,11,0,0) call hardware_rtc_set_alarm(6,3,1,11,20,00,hardware_alarm_every_hour,1)
Using this code, after 20 minutes you should receive an event.
I finally understood the operation !
Thanks for the help
