3.3 Power Modes and commands
1
The RS9110-N-11-2X module supports three power modes with the UART
interface. The Host can switch among the power modes using the AT commands
depending on the Wi-Fi connection status as defined in this section.
The power modes supported by the RS9110-N-11-2X module for UART interface
are classified based on the Host‟s capability to negotiate with RS9110-N-11-2X
and the Wi-Fi connection status. Please refer to the Wi-Fi commands section for
details on the AT commands required to configure the module in different power
modes.
3.3.1 Power mode 0
In this mode, power save is disabled. The module will be in Power Mode 0 by
default.
3.3.2 Power mode 1
The RS9110-N-11-2X module can put the Baseband, RF and also the Core
Control block to sleep in this mode.
The average amount of power consumed in this mode would depend on the
sleep period and also on the time taken to exchange the SLEEP and ACK
messages.
The functioning of the module in this mode depends on the connection status as
explained below
Before Wi-Fi connection
In this state, the module is configured with a sleep timer through the
at+rsi_sleeptimer command. The input to this command indicates the amount of
time the module puts the Core Control Block to sleep. Once the timer expires,
the module wakes up the Core Control block and sends the “SLEEP\r\n” , in
upper case ASCII ( 0x53 0x4C 0x45 0x45 0x50 0x0D 0x0A) message to the
Host. If the Host sends “ACK\r\n”, in upper case ASCII ( 0x41 0x43 0x4B 0x0D
0x0A), the module will put to sleep the Core Control block for another interval of
the sleep period. But, if the host wants to perform any Wi-Fi related activity viz.,
SCAN, JOIN, etc., it has to issue these commands accordingly to the module.
