wake-up source, and

communication has an error, 2 others automatic retries are done.
(2) : Only if done inside the active interval and

is
true
. Note: if the RTC has never been updated, the active interval is 7/7 days
24/24 hours.
(3) :
Yes
means
pictureframe.key.enabled
=
true
or
pictureframe.nfc.enabled
=
true
.
(4) : Launch NFC detection for NFC writer and NFC tag for a fixed duration.
(5) : If
Unlock/lock keys
action is programmed for
After NFC tag
or
After NFC Writer
wake-up reason,the NFC detection is done first. Once the NFC is detected, the
key detection is done just after, if the key is unlocked. If a key is detected, the
After key
actions are done. Then the actions
Send HID tag over WPAN1
or
NFC Writer NDEF
actions become possible during
After key
actions. If no key is detected, the actions
After NFC writer
or
After NFC Tag
can be done.
(6) : If
pictureframe.testcard.enabled
is
true
and if an USB power bank is connected, the SLATE106 is exiting sleep mode automatically until the powerbank is unplugged.
