Switching on the HC15

The HC15 can be started by pressing the IGT key of the DSB75. Please wait approximately
2 seconds before using the module, for example before entering AT commands.
Disconnecting and plugging the USB cable during operation is not supported.
3.3

Switching off the HC15

To shut down the HC15 module, enter the AT^SMSO command. This enables the ME to
save all data and perform an orderly shutdown.
AT^SMSO
OK
The HC15 module can also be switched off by using the IGT line as described in [1] (see
AT^SCFG) and [1] (see section "Configuring the IGT Line for Use as ON/OFF Switch").

Registering to the Network

Make sure to operate the HC15 always with the UICC card inserted in the DSB75 card
reader and a valid SIM PIN entered. This is because most AT commands require SIM PIN
authentication.

at+cpin?
+CPIN: SIM PIN
OK
at+cpin=1234

at+cpin?
