Description
Suggested usage
AT+COPS?
+COPS: <mode>[,<format>,<oper>[,<AcT>]]
It returns the current registered PLMN in the
configured format, RAT is fixed to 7 (LTE, Cat-
M1).
Periodically (30 s) and when detecting
problems
AT+CGDCONT?
+CGDCONT: <cid>,<PDP_type>,<APN>,<PDP_addr>
,<d_comp>,<h_comp>[,<IPv4AddrAlloc>,<reques
t_type>,<P-CSCF_discovery>,<IM_CN_Signallin
g_Flag_Ind>[,<NSLPI>[,<secure_PCO>[,<IPv4_M
TU_discovery>[,<Local_Addr_Ind>]]]]]
It returns the active and defined EPS bearers
with the APN used and the IP type and
addresses.
Periodically (30 s) and when detecting
problems
AT+CPOL?
+CPOL: <index1>,<format>,<oper1>[,<GSM_AcT1
>,<GSM_Compact_AcT1>,<UTRAN_AcT1>[,<E-
UTRAN_AcT>]]
It returns the high priority PLMN list, which
might change at SIM refresh.
Module initialization and SIM refresh, only in
debug/test mode
AT+CEDRXRDP
+CEDRXRDP: <AcT_type>[,<Requested_eDRX_cycl
e>,<Assigned_eDRX_cycle_value>,<Assigned_pa
ging_time_window>]
It returns the current eDRX parameters
assigned by the mobile network.
If eDRX is used, the host should monitor CTS
line to avoid waking up the module during
eDRX/sleep periods
AT+CPSMS?
+CPSMS: <mode>,[<Requested_Periodic_RAU>],[
<Requested_GPRS_READY_timer>],[<Requested_P
eriodic_TAU>],[<Requested_Active_Time>]
It returns the PSM settings as required to the
network. As setting is persistent, if the
network does not grant PSM, the module will
propose the PSM timers at every attach and
registration attempt.
Module initialization
AT+UCPSMS?
+UCPSMS: <mode>,[<Assigned_Periodic_RAU>],[
<Assigned_GPRS_READY_timer>],[<Assigned_Per
iodic_TAU>],[<Assigned_Active_Time>],[<Assi
gned_Periodic_TAU_Format_Type>]
It returns the PSM settings as assigned by the
network. If PSM timers are not reported by
+CEREG, this command can be periodically
polled. Periodic TAU timer is also reported.
At change of registration information (as
reported by +CEREG)
