Wi-Fi Power Management Messages
The messages in this section are used to set the power mode for WiComm-Socket. Note that PSPOLL modes are only
applicable to Infrastructure networks.
6.9.1
SET_POWER_SAVE_MODE_MSG
(102 COMMAND)
This message sets Power Save mode for WiComm-Socket. Options include full power, an AP polling mode with self set
wake up times, an AP polling method using the DTIM period set by the AP, and a Hibernate (radio module off) mode.
By default, Power Save mode of the module is 4 (Power Save mode Off).
IMPORTANT:
1)Hibernate mode can only be exited through a WiComm Reset. This can be performed through the API, or by using
the physical reset pin. After exiting reset, the device must be reinitialized including any connection profile information to
reestablish a connection.
2)When using the Power Save mode of 3, the self set wake up period is used only after it is negotiated with the AP. In
practice it is suggested that the DTIM listen interval be set while disconnected so that it is applied during the connection
process. The AP may choose not to allow association with the radio if the DTIM listen interval is too long.

DTIM Listen Interval in PSPOLL mode (self-set wake up time in Power Save
mode 3). Actual time is this interval multiplied by 100msec, e.g. 10 = 1second.
