4.9. Enter PIN/PUK code +CPIN

This command is used to validate the PIN code, or to validate the PUK

code (and define a new PIN code).

If the user application try to establish an outgoing call before having

validated the SIM PIN code, then the GSM module will refuse the "ATD"

command with a "+CME ERROR: 11" (SIM PIN required).

It's up to the application to validate the PIN after each reset or power on.

The application shall therefore use the command :

AT+CPIN="<pin>"

Application to GSM AT+CPIN=1234 enter PIN

GSM to application OK PIN correct

Application to GSM AT+CPIN=5678 enter PIN

GSM to application +CME ERROR: 16 incorrect password

After 3 unsuccessful codes, the PUK will then be required. The PUK

validation forces the user to enter as a second parameter a new PIN code

which will be the future PIN code if the PUK validation succeeds. The

application shall therefore use the command :

AT+CPIN="<puk>","<new pin>"

Application to GSM AT+CPIN=1234,5896 enter PUK and new PIN

GSM to application OK PUK correct

Application to GSM AT+CPIN=5000,5896 enter PUK and new PIN

GSM to application +CME ERROR: 16 incorrect password

To know which code has to be entered (or not), the following

interrogation command will be implemented :

AT+CPIN?

The possible responses are :

+CPIN: READY No PIN is needed

+CPIN: SIM PIN PIN is required

+CPIN: SIM PUK PUK is required

+CME ERROR: <err> SIM failure, SIM absent etc.

Please note that in this case the mobile does not finish its response with

the OK string.
