Startup from shipping mode: blink blue LED 3 times (exit shipping mode),
blink white LED 5 times (application start).
Startup/reset normal: blink blue LED 3 times (bootloader), blink white LED 5
times (application start).
Operation mode: 1 White blink fast during location scan
Cloud sync: see cloud sync behavior
Device cannot connect/constantly resetting: the blue LED will blink 3 times,
then there will be a pause, and the blue LED will blink 3 more times. This
behavior will continue indefinitely, without the device’s white LED blinking.
This means that the device has an error. Some causes are: low battery;
battery types that cannot handle the pulse current for LTE-M.
Cloud sync
The cloud sync feature allows the user to force the device to send an uplink
and check for any pending mailbox messages. When the cloud sync
pushbutton sequence is performed the device will immediately send a
diagnostic event count message and check downlink mailbox using the
current modes network (SymBLE or LTE-m). If a location update is in
progress this will also be sent with the uplink; however, if a GPS is in
progress the scan will be stopped due to potential long GPS scan times and
the next location type will be started.
The LED is used to indicate to the user the result of the downlink mailbox
check:
1 - Green LED blink (5s): downlink mailbox check success with mail
2 - White LED blink (5s): downlink mailbox check success no mail
3 - Red LED blink (5s): downlink mailbox check failed
