Logger synchronizes the time settings with the network every time it communicates. If you manually set
the time and the logger will be able to fetch the time from the network, it will overwrite the manual
settings.
Logger status
Efento loggers collect information about its current status. This information is useful for troubleshooting
and solving the connectivity issues. Information about current logger status can be accessed with Efento
Logger application or remotely, from the server. If you want to integrate Efento loggers into your cloud /
server platform and want to receive the information about the logger status, please refer to “Efento
NB-IoT loggers integration manual”.
Cellular status
Current device’s cellular status can be checked in the “Cellular status” tab (connect to the logger ->
three dots in the upper right corner -> “Cellular status”). In the tab, you can see the following information:
● Supported technologies - what celular technologies are supported by the device. There are two
options: NB-IoT or NB-IoT & LTE-M
● Current technology - what technology is currently in use. For NB-IoT only loggers it will always
be NB-IoT, For NB-IoT & LTE-M logger, current technology depends on the technology which is
currently in use. Devices automatically switch between technologies, depending on the inserted
SIM card
● Registration status - indicates current network communication status:
○ REGISTERED - registered to the network - this is typical status of the device;
○ NOT REGISTERED, SEARCHING - not registered to the network, searching for it - this
status may be seen during device power up, when it did not manage to attach to the
network yet;
○ NOR REGISTERED_NOT_SEARCHING - not registered to the network, not searching
for it - this status is seen mainly, if there is no network coverage;
○ REGISTRATION DENIED - network did not allow device to register
○ REGISTERED ROAMING - if the device is registered in roaming
○ REGISTERED EMERGENCY ONLY
○ UNKNOWN - all the other states
● Registration reject cause - if the device is not able to register to the network, the cause is
displayed in this field. Reject causes are described in 3GPP TS 24.301 Annex A
● Signal strength - strength of the signal
● Communication status - describing current status of communication with the server. Possible
statuses: OK, server error, encoding error, socket error, timeout, mismatch, unauthorized,
unexpected error, not registered, not supported
● IMEI - IMEI number of the cellular module
● ICCID - ICCID of the SIM card in the device
● IP address - current IP address of the device
