Various Operating Modes
There are various kinds of operating modes for the WS6318 embedded module as defined in the figure and table below.
Figure 51. WS6318 Operating Modes Flowchart
Table 52. WS6318 Embedded Module Operating Modes
Mode Description
OFF Mode When VBATT power is supplied to the WS6318 embedded module but has not yet been powered ON.
Alarm Mode
When alarm clock is set for the WS6318 embedded module with ALL of the following conditions:
• before time is up
• with AT+CPOF having been entered from a computer that is connected to the WS6318 embedded module
• with the ON/~OFF signal being left open (remains at HIGH level)
Active Idle Mode When the WS6318 embedded module is active and synchronized with the network, but currently has no communication.
Sleep Idle Mode When the WS6318 embedded module has a location update with a live network but with no GSM/GPRS connection, while the UART interface is in sleep mode.*
Airplane Mode When the SIM device and GSM/GPRS features are NOT available and the embedded application is running while the UART remains active.

Mode Description
Transfer Mode The WS6318 embedded module has GPRS data transfer connection with a live network.
* There are two different methods to enter sleep mode through the AT command setting, AT+PSSLEEP, as described in the following sub-section.
6.1.1.
Using AT+PSSLEEP to Enter Sleep Mode
• AT+PSSLEEP=0
The entry of sleep mode is controlled by the level of DTR signal and the firmware.
When DTR (viewed from the embedded module side) is of LOW voltage level, the WS6318 embedded module will never enter sleep mode.
When DTR (viewed from the embedded module side) is of HIGH voltage level, the WS6318 embedded module will enter sleep mode. To wake the WS6318 embedded module up, it is necessary to toggle the DTR (viewed from the embedded module side) from HIGH to LOW voltage level.
This method should be applied if the application needs to forbid the entry of sleep mode. • AT+PSSLEEP=1
For this method, the entry of sleep mode is controlled just by the firmware.
When the WS6318 embedded module has had no activities for a certain period of time, it will enter sleep mode automatically, regardless of the DTR level.
Any ASCII character on the UART can wake the WS6318 embedded module up. Note that due to the wake-up mechanism of the WS6318 embedded module, it is recommended to have at least 10ms latency time after the wake-up character before sending AT commands to the embedded module.
For details of the AT+PSSLEEP command, please refer to document [1] AT Command Manual for AirPrime WS6318.
Note that the power consumption level will vary depending on the operating mode used.
6.2.
Power Consumption
The power consumption level will vary depending on the operating mode, and it is for this reason that the following consumption values are given for each mode and RF band.
Three VBATT values are used to measure the power consumption: VBATTmin (3.2V), VBATTmax (4.8V) and VBATTtyp (3.6V).
The average current is given for the three VBATT values and the peak current given is the maximum current peak measured with the three VBATT voltages.

* Sleep Idle Mode consumption depends on the SIM card used. Some SIM cards respond faster than others, in which case the longer the response time is, the higher the consumption is. Sleep Idle Mode consumption will be higher if the ON/~OFF pin is kept at low voltage level. Refer to Figure 33 Power-ON Sequence (no PIN code activated) for more information.

Recommendations for Less Consumption
For better power consumption, particularly for the quiescent current, it is recommended to drive the GPIOs and the WISMO_READY signal as shown in the table below.
