Diagnostic information via URCs
Command
URC
Description
Can be polled
AT+CSCON=1
+CSCON: 1
Return the status of the RRC connection (idle or connected). Persistent
setting.
Yes
AT+CREG=3
+CREG: <stat>[,[<lac>],[<ci>][,[<AcTStatus>
][,<cause_type>,<reject_cause>]]]
Enable registration status URC for non-EPS services (for example, SMS) and
reject cause in case of unavailability of such services.
Yes
AT+CEREG=5
+CEREG: <stat>[,[<tac>],[<ci>],[<AcT>][,[<c
ause_type>],[<reject_cause>][,[<Assigned_Ac
tive_Time>,[<Assigned_Periodic_TAU>]]]]]
Enable registration status URC for EPS services, reject cause in case of
unavailability of such services and PSM related timers if granted by the
network.
Yes
AT+CGEREP=2,1
+CGEV: NW PDN DEACT <cid>
Report all registration and PDN connectivity status events. The first parameter
of the AT command is set to 2 indicate that URC will not be discarded in case
the AT interface is busy.
No
AT+CTZR=1
+CTZV: <tz>
Enable reporting of changes in time zone. Usually, time zone information is
provided by the network at LTE attach only.
No
AT+CMER=1,0,0,2,1
+CIEV: <descr>,<value>
Report variations in some indicators like roaming, SIM indication (provided that
the feature is configured via +UGPIOC), signal level.
No
AT+CNMI=2,1
+CMTI: <mem>,<index>
Report the index in current selected memory (can be the factory-programmed
setting ME or SIM, see +CPSM read command) where the mobile terminated
SMS has been stored. The first parameter set to 2 indicates that URC are
buffered in case of busy AT interface. The setting is volatile and shall be
re-entered at every switch on or exit from PSM.
No
AT+USIMSTAT=7
+UUSIMSTAT: <state>
Report SIM initialization progress, SIM phonebook initialization progress, and
SIM REFRESH events (each group of URCs can be singularly disabled). SIM
Refresh URC might indicate the change of some operational parameters in the
UICC card (for example, IMSI swap, SIM profile installation after remote SIM
provisioning). The setting is persistent.
No
AT+UBIP=1
+UUBIP: <ev_cmd>,<val>
URC are raised when Open Channel, Close Channel, Send Data, Receive Data
and Channel status events are issued by the SIM card towards the device to
handle a SIM OTA session, for example for remote SIM provisioning. The
embedded BIP client will cater for establishing the required socket and
exchange data with the SIM OTA server. The setting is persistent.
No
AT+UFOTASTAT=1
+UFOTASTAT: <event>,<param1>[,<param2>]
Provide information on the progress and outcome of the Firmware download
over the air via LwM2M (uFOTA). The setting is persistent.
No
AT+ULWM2MSTAT=1
+ULWM2MSTAT: <event>,<param1>[,<param2>]
Enable URC to report the activity of the embedded LwM2M client. The setting
is persistent.
No
