7.14.1Description
Configures the UEs extended discontinuous reception (eDRX) parameters. The command controls whether the
UE wants to apply the eDRX or not, as well as the requested eDRX cycle and paging time window values for
each specified type of radio access technology.
The set command also enables the +CEDRXP URC, that is issued on any change in the eDRX parameters, when
enabled by the network.
The set command with <mode>=3 will disable the use of eDRX and reset all parameters to factory-programmed
values. Optional parameters are not provided in this form of command.
The read command returns the requested eDRX cycle and paging time window values. See the +CEDRXP URC
and the +CEDRXRDP AT command to see if eDRX is enabled by the network and retrieve the values assigned
by the network.
The parameters are omitted in the information text response to the read command when the eDRX is not
enabled on any RAT.
SARA-R410M / SARA-R412M / SARA-N4
Deregister the module from the network to change the command setting. Issue AT+COPS=2 or AT
+CFUN=0 to deregister from network, issue the +CEDRXS command and reboot the module (by means of
the AT+CFUN=15 command) in order to apply the +CEDRXS settings.
SARA-R4 / SARA-N4
If the +CEDRXS AT command has not been issued after selecting a MNO profile, the module applies
the default <Requested_eDRX_cycle> and <Requested_paging_time_window> profile values (see Mobile
Network Operator profiles). If the set command is issued and any of the optional parameters is omitted,
the module applies the last set values.
