Operating Mode
Description
Transition between operating modes
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 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.
