2.13 Operating Models
The following table briefly outlines the operating modes to be mentioned in the following chapters.
| Mode | Detail | |
| Normal Operation | idle | Software is active. The module has registered on the network, and it is ready to send and receive data |
| Talk/Data | The network connection is ongoing. In this mode, the power consumption is decided by network setting and data transfer rate. | |
| Minimum Functionality Mode | AT+CFUN command can set the module to a minimum functionality mode without removing the power supply. In this case, both the RF function and (U)SIM card will be invalid. | |
| Airplane Mode | AT+CFUN command or W_DISABLE# pin can set the module to airplane mode. In this case, the RF function will be Invalid. | |
| Sleep Mode | In this mode, the current consumption of the module will be reduced to a minimal level. In this mode, the module can still receive paging message, SMS, voice call, and TCP/UDP data from the network normally | |
| Power Down Mode | In this mode, the power management unit shuts down the power supply. The software goes inactive. The serial interface is not accessible. Operating voltage remains applied | |
2.14 Power Saving
2.14.1 Sleep Mode
EG91 Mini PCIe can reduce its current consumption to a minimum value in sleep mode. There are three preconditions that must be met to make the module enter sleep mode.
- Execute AT+QSCLK=1 to enable sleep mode
- Ensure the DTR is kept at a high level or be kept open
- The host’s USB bus, which is connected with the module’s USB interface, enters suspend state
2.15 Airplane Mode
When the module enters airplane mode, the RF function will be disabled, and all AT commands related to it will be inaccessible.
