I've observed that the default power mode for the WiFI adaptor on my Android phone is PSM ( Power save mode) as opposed CAM ( where the radio never turns off). I've observed that certain network activity within applications such as youtube and sipdroid triggers the wifi adaptor on the phone to leave PSM and be fully awake. My questions are :
1.) Is this behavior completely handled within the wifi kernel driver? In tiwlan.ini, defaultPowerLevel = 0 Which seems to indicate that the driver can switch between the different modes with an internal algorithm. 2.) Is there some API call that can tell the wifi driver to change from PSM to full power mode? There is nothing apparent in the pubic API that leads me to believe this. However in: wifi.java.android.net.wifi.WifiNative.java, There is an API call : setPowerModeCommand(int mode); That seems to indicate option #2 is possible.
