/*******************************************************************************
Function:
void WF_PsPollEnable(bool rxDtim, bool aggressive)
Summary:
Enables PS Poll mode.
Description:
Enables PS Poll mode. PS-Poll (Power-Save Poll) is a mode allowing for
longer battery life. The MRF24W coordinates with the Access Point to go
to sleep and wake up at periodic intervals to check for data messages, which
the Access Point will buffer. The listenInterval in the Connection
Algorithm defines the sleep interval. By default, PS-Poll mode is disabled.
When PS Poll is enabled, the WF Host Driver will automatically force the
MRF24W to wake up each time the Host sends Tx data or a control message
to the MRF24W. When the Host message transaction is complete the
MRF24W driver will automatically re-enable PS Poll mode.
When the application is likely to experience a high volume of data traffic
then PS-Poll mode should be disabled for two reasons:
1. No power savings will be realized in the presence of heavy data traffic.
2. Performance will be impacted adversely as the WiFi Host Driver
continually activates and deactivates PS-Poll mode via SPI messages.
Precondition:
MACInit must be called first.
Parameters:
rxDtim - true if MRF24W should wake up periodically and check for
buffered broadcast messages, else false
Returns:
None.
Remarks:
None.
