I found the rtc driver "file" /proc/driver/rtc
Immediately after running my event script I see..
Code:
[root@kindle bin]# cat /proc/driver/rtc
rtc_time : 17:47:42
rtc_date : 2017-06-30
alrm_time : 18:02:14
alrm_date : 2017-06-30
alarm_IRQ : yes
alrm_pending : no
update IRQ enabled : no
periodic IRQ enabled : no
periodic IRQ frequency : 1
max user IRQ frequency : 64
24hr : yes
It's exactly the alarm time I set minus 2h (my timezone) and also the current time fits. Why it is not waking the Kindle. Maybe that alarm pending thing?
