Operating Mode
Description
Transition between operating modes
Active-Mode
Module is switched on with application
interfaces enabled or not suspended: the
module is ready to communicate with an
external device by means of the application
interfaces unless power saving configuration is
enabled by AT+UPSV (see 1.9.1.4, 1.9.2.4 and
u-blox AT Commands Manual [3]).
When the module is switched on by an appropriate power-on event
(see 1.6.1), the module enters active-mode from power-off mode.
If power saving configuration is enabled by the AT+UPSV command,
the module automatically switches from active to idle-mode
whenever possible and the module wakes up from idle to active-
mode in the events listed above (see idle-mode to active-mode
transition description above).
When a RF Tx/Rx data connection is initiated or when RF Tx/Rx is
required due to a connection previously initiated, the module
switches from active to connected-mode.
Connected-Mode
RF Tx/Rx data connection is in progress.
The module is prepared to accept data signals
from an external device unless power saving
configuration is enabled by AT+UPSV (see
sections 1.9.1.4, 1.9.2.4 and u-blox AT
Commands Manual [3]).
When a data connection is initiated, the module enters connected-
mode from active-mode.
Connected-mode is suspended if Tx/Rx data is not in progress, due
to connected discontinuous reception and fast dormancy capabilities
of the module and according to network environment settings and
scenario. In such case, the module automatically switches from
connected to active mode and then, if power saving configuration is
enabled by the AT+UPSV command, the module automatically
switches to idle-mode whenever possible. Vice-versa, the module
wakes up from idle to active mode and then connected mode if RF
Tx/Rx is necessary.
When a data connection is terminated, the module returns to the
active-mode.
