The following commands are the complete set required to select and configure the power modes and use models described in this chapter. No sleep-level configuration is required or exposed. Section 4.6.1 covers the additional settings that reduce current by disabling functions an application does not need.
| Command | Purpose |
|---|---|
| AT+CFUN | Set modem functionality: 0 minimum, 1 full, 4 flight mode. The module boots at CFUN=0 and does not attach automatically, giving the host full control of the attach sequence. The boot level is configurable with %MODEMCFG="CfunInit". |
| AT+CPSMS | Request 3GPP Power Saving Mode timers T3324 and T3412-ext. |
| AT+CEDRXS, AT%PTWEDRXS | Request the extended DRX cycle and the Paging Time Window, 1.28 s to 20.48 s. |
| AT%MODULECFG="autoPowerSave" | Enable (1) or disable (0, default) power saving within System ON. Can be changed only while the current sleep mode is System ON IDLE. Takes effect on radio activation. Not retained across a reset. |
| AT%MODULECFG="slpWaitTime" | Time in ms for which the module stays awake after each wake-up. Default 1000 ms. Reduce this to lower the average current on short duty cycles. |
| AT%MODULECFG="pmuInCdrx" | Allow (1, default) or inhibit (0) power-saving sleep during connected DRX. |
| AT%SYSOFF | Enable or disable System OFF. Requires UART1 at a fixed baud rate of 9600 bps or lower. |
| AT%POWD | Enter System Disabled. |
