State machine

The state machine focuses on the main states of the module; states of the

mobile radio (Radio On/Off) and the GPS radio (GPS On/Off). The transitions

in the state machine that require the Software (radio) and GPS to be enabled

can be made using the WMCore service (recommended) or AT commands

directly. In Windows 7, several of the transitions are caused by the WWAN

(Network) driver.

The transition between HW Off and states where the radio is on can be made

automatically by the module without including any host software, see chapter

2.2.

The module supports a SW Off (D3 hot) state where most functionality is

turned off in the mobile broadband module. The main intention with the state is

to prepare the module to be powered off. Among other things is the SIM card

turned off. In the SW Off state it is possible to turn the module back on again

using AT commands (AT+CFUN). When the module is turned on the SIM card

is reset and all functionality of the mobile broadband module is turned on

again.

Additionally, the module supports a separate HW control of GPS Off, see

chapter 4.3.6.2. This feature is not depicted in Figure 25.
