Motorola W24 ユーザーズマニュアル

regardless of the original wake-up reason or source. W24 will remain awake while data is 
transferred.

Only when the serial interface transfer is completed and the data has been processed, W24 will 
return to low power mode automatically, according to the AT+iPSE settings (see 

).

The W24 low power mode is enabled and disabled by the AT+iPSE command.

To permanently terminate the W24 low power mode, the AT+iPSE = 0 command must be used. 
Setting AT+iPSE = 0 disables the currently active low power mode and switches W24 to Idle 
mode.

W24 will not return to low power mode until an AT+iPSE > 0 commands is set again.

This command can be sent only when the serial interface is active.

In case the serial interface is disabled, it must first be activated before sending this command. To 
reactivate the serial interface, a temporary termination of the low power mode is required, as 
described in 

Following the temporary low power mode termination, the serial interface will activate and the 
AT+iPSE = 0 command can be received by W24.

In case that W24 cannot locate an active access point or cannot register to it, W24 will enter the 
Deep Sleep Mode.

During Deep Sleep Mode, network connection does not exist. W24 will periodically come out of 
the Deep Sleep Mode, to attempt to locate APs. If the search is not successful, the module will 
return to the Deep Sleep Mode.

The time between consecutive attempts to locate an AP is set by the AT+iWLSI command.
