7.2.7.3: Power mode 2
R

The RS9110-N-11-2X module powers off the Baseband and RF components in
this mode. The Core Control block interacting with the Host is always
functional in this mode. Hence, the module can receive commands from the
host at any time.
NOTE: The average current consumption in Power Mode 2 is higher than
Power Mode 1.
The functioning of the module in this mode depends on the connection status
as explained below

In this state, the module is configured with a sleep timer. Once the
timer expires, the module powers on the Core Control block and
sends the request for sleep permission to the Host again. On
getting permission the Host, the module will power off the Core
Control block for another interval of the sleep period.
If the host wants to perform any Wi-Fi related activity like scanning
or joining networks, it has to switch to Power Mode 0. After a
connection is established, it can switch back to Power Mode 1 or 2.
In this state, the RS9110-N-11-2X module periodically wakes up to
receive beacons from the Access Point (AP). If there is no data to
be transmitted or received to/from the Access Point, it powers off
the Baseband and RF components and requests the Host
permission to turn off the Core Control block. On receiving
permission from the Host, the module goes to sleep and wakes up
before the next beacon comes.
If this power mode is enabled before the Wi-Fi connection is
established, the module powers off the Baseband and RF
components until the Host reconfigures the module to Power Mode
0.
If the host wants to perform any Wi-Fi related activity like scanning
and joining networks, it has to switch to Power Mode 0. This can be
done at any time during the operation. The Host can switch back to
Power Modes 1 or 2 after the Wi-Fi connection is established.
In this state, the RS9110-N-11-2X module gets information from
the Access Point to which it is connected for any buffered data at
every beacon. If there is no data to be transmitted or received
to/from the Access Point, it powers off the Baseband and RF
components.
