1.6.3 Module reset
TOBY-L2 and MPCI-L2 series modules can be properly reset (rebooted) by:
AT+CFUN command (see u-blox AT Commands Manual [3]).
MPCI-L2 series modules can be additionally properly reset (rebooted) by:
AT+CPWROFF command (see u-blox AT Commands Manual [3]): the behavior differs than TOBY-L2 series, as
MPCI-L2 modules will reboot rather than remain switched off due to modules’ internal configuration.
In the cases listed above an “internal” or “software” reset of the module is executed: the current parameter
settings are saved in the module’s non-volatile memory and a proper network detach is performed.
An abrupt hardware reset occurs on TOBY-L2 and MPCI-L2 series modules when a low level is applied on the
RESET_N or PERST# input pin for a specific time period. In this case, the current parameter settings are not saved
in the module’s non-volatile memory and a proper network detach is not performed.
It is highly recommended to avoid an abrupt hardware reset of the module by forcing a low level on the
RESET_N or PERST# input during modules normal operation: the RESET_N or PERST# line should be set
low only if reset or shutdown via AT commands fails or if the module does not provide a reply to a specific
AT command after a time period longer than the one defined in the u-blox AT Commands Manual [3].
As described in Figure 17, the RESET_N and PERST# input pins are equipped with an internal pull-up to the VCC
supply in the TOBY-L2 series and to the 3.3 V in the MPCI-L2 series.

1.6.4 Module configuration selection by host processor
The HOST_SELECT0 and HOST_SELECT1 pins are not available on MPCI-L2 series modules.
The selection of the module configuration by the host application processor over the HOST_SELECT0 and
HOST_SELECT1 pins is not supported by all the TOBY-L2 series modules product versions.
TOBY-L2 series modules include two input pins (HOST_SELECT0 and HOST_SELECT1) for the selection of the
module configuration by the host application processor.
