6 Power Save Modes
It is possible to lower the module power consumption by configuring different power save
modes. Generally, lowering the overall power consumption leads to higher system response
times. It is hard to find a configuration to fit all needs and it might be a good idea to experi-
ment with different configurations to find one that fits the application.
To understand the power settings it’s important to understand that the OWSPA311g has two
independent chips that have individual power saving features. The two chips are the wlan radio
chip and the processor.
Independently of what power save mode is configured, the processor can be configured to en-
ter its idle mode when idle. This is configured using the ATS4005 AT command. By default, the
processor enters idle mode. Turning off the idle mode feature will increase the throughput
slightly.
The OWSPA311g has three different power saving modes.
6.1 Power Modes
Online Mode
The online mode does not have any power save features.
Sleep Mode
This mode is the default. In this mode the radio chip will utilize power save in both connected
and disconnected mode. Wake up latency in connected mode is determined by how often the
access point sends out beacons. The amount of power saved is also determined by how often
the access point sends out beacons as well as the DTIM values.
In Ad-hoc mode the radio cannot perform any power saving whilst associated. Power saving in
disassociated mode is still possible though.
Stop Mode
In Stop mode the radio chip behaves exactly as in Sleep mode. The module will keep its connec-
tion to the access point. The difference here is the processor.
The processor will try to power down itself into a state where it is completely shut off except for
a few interrupts. There are only two things that can wake up the processor from this state. The
first one is automated and is activated by the radio chip when new data is available. The other
one is the DSR pin of the UART. If the DSR pin is disabled the module will try to enter Stop
mode. If this pin is enabled, the OWSPA311g will wake up from Stop mode.
After the DSR pin has been disabled there is an adjustable timer setting that the OWSPA311g
waits until it tries to enter Stop mode. The OWSPA311g will not enter Stop mode if it still has
things to do. It will enter it as soon as it deems possible after the timer has elapsed.
If the DSR pin is enabled the processor will of course idle if there is nothing to do. A module in
Stop mode with the DSR pin enabled therefore behaves the same way as a module in Sleep
mode.
