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
When the modules are switched on by an appropriate
power-on event (see 1.6.1), the module enter 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
When a data connection is initiated, the module enters
connected-mode from idle-mode.
If power saving configuration is enabled by the AT+UPSV
command, the module automatically switches from
connected to active and then idle-mode whenever possible
and the module wakes up from idle to active and then
connected mode if RF Transmission/Reception is necessary.
When a data connection is terminated, the module returns
to the active-mode.
