Monitoring module status

C1-Public
Command
URC
Description
Can be polled
AT+CEINFO=1
+CEINFO: <reporting>,<CE_enabled>,<UE_state
>,<downlink_repetition_factor>,<uplink_repe
tition_factor>,<RSRP_value>,<CINR>
Volatile setting, it reports variation of the Coverage extension mode and
related transmission parameters (for example, repetitions schemes to be used)
detected by the device or assigned by the network.
Yes
AT+CEDRXS=1
+CEDRXP: <AcT_type>[,<Requested_eDRX_cycle>
[,<Assigned_eDRX_cycle>[,<Assigned_paging_t
ime_window>]]]
If eDRX is used by the host application, the URC can report changes in eDRX
settings imposed by the network in different areas or times. The setting is
persistent.
Yes
☞
Always consider to apply the
+CGEREP
AT command with <mode> equal 2, for example
AT+CGEREP=2
, in order to avoid to lose URCs when the
AT interface is busy in executing some other AT commands.

Description
Suggested usage
ATI
ATI9
SARA-R422M8S-00B-00
00.06,A00.00
Return the model and FW identification, useful
for tracking purposes.
Module initialization
AT+CGSN
355438110017558
Return the IMEI.
Module initialization
AT+CIMI
AT+CCID
001010123456789
+CCID: 89860000502000180722
Return the SIM identities for tracking
purposes. They can change after a SIM refresh
event that can be reported by +UUSIMSTAT
URC.
Module initialization
AT+UBANDMASK?
+UBANDMASK: 0,185079967,2,1,134748319,10486
42,2,2621824
Return band mask selection.
Module initialization
AT+UMNOPROF?
+UMNOPROF: 90
Return MNO profile set.
Module initialization
AT+UCGED?
+UCGED: 2
6,<svc>,<MCC>,<MNC><EARFCN>,<Lband>,<ul_BW>

avgPucchPwr>,<drx>,<l2w>,<volte_mode>[,<mea
s_gap>,<tti_bundling>
Return several cell parameters as measured by
the module or provided by the network. Some
values like CQI and signal indicators are
periodically refreshed in the module on a 0.5 s
base, so the application should average them.
Low periodicity
AT+CESQ?
+CESQ:,,,,<rsrq>,<rsrp>
Return signal quality and level, and it is more
precise than +CSQ. It is subjected to
transitions due to local reset of values at
changes in RRC state (idle, connected) so the
host application should average the values.
Periodically (for example, every 50 to 10 s)
