3.2Switching 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.
3.3Switching 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 | The ME switches off. |
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”).
3.4Registering 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.
Write command: AT+CPIN=<pin>[, <new pin>]
at+cpin? | Entering the SIM PIN. |
+CPIN: SIM PIN |
|
OK |
|
at+cpin=1234 |
|
OK |
|
at+cpin? |
|
+CPIN: READY |
|
OK |
