4.4.2 Enter PIN2 +CPIN2
This specific command is used to validate the PIN2 code (CHV2), or to
validate the PUK2 code (UNBLOCK CHV2) and to define a new PIN2 code.
Of course +CPIN command allows to validate PIN2 or PUK2 codes but only
when the last executed command resulted in PIN2 authentification
failure.
The PIN2 length is between 4 and 8 digits, the PUK2 length is 8 digits only.
AT+CPIN2=<pin2>
Application to GSM AT+CPIN2=1234 enter PIN2
GSM to application OK PIN2 code is correct
Application to GSM AT+CPIN2=5678 enter PIN2
GSM to application +CME ERROR: 3 operation not allowed, PIN2 previously entered
After 3 unsuccessful codes, the PUK2 will then be required. The PUK2
validation forces the user to enter as a second parameter a new PIN2 code
which will be the new PIN2 code if the PUK1 validation succeeds. The
application shall therefore use the command:
AT+CPIN2=<puk2>,<NewPin2>
Application to GSM AT+CPIN2=00000000,1234 enter PUK2 and new PIN2
GSM to application +CME ERROR: 16 Incorrect Password (PUK2)
Application to GSM AT+CPIN2=12345678,1234 enter PUK2 and new PIN1, 2
nd
attempt
GSM to application OK PUK2 correct, new PIN2 stored
To know which code has to be entered (or not), the following interrogation
command can be used:
AT+CPIN2?
The possible responses are:
+CPIN2: READY No PIN2 is needed
+CPIN2: SIM PIN2 PIN2 is required
+CPIN2: SIM PUK2 PUK2 is required
+CME ERROR: <err> Absent (10) etc...
4.4.3 PIN remaining attempt number +CPINC
This specificspecific command instructs the module to display the number of valid
tries for PIN1 (CHV1), PIN2 (CHV2), PUK1 (UNBLOCK CHV1) and PUK2
(UNBLOCK CHV2) identifiers.
Command syntax: AT+CPINC
Response syntax: +CPINC: <n1>,<n2>,<k1>,<k2>
<n1>, <n2> are the remaining tries of PIN1, PIN2 (0 = blocked, 3 max)
<k1>, <k2> are the remaining tries of PUK1, PUK2 (0 = blocked, 10 max)
To make it running, the card should be present at the initialisation time, in
the opposite case, an error will be sent (+CME ERROR: 10).
Application to GSM AT+CPINC Ask remaining tries
GSM to application +CPINC: 2,3,10,10 First CHV1 attempt was a failure
Application to GSM AT+CPINC? Ask current values
GSM to application +CPINC: 2,3,10,10 First attempt was a failure
Application to GSM AT+CPINC=? Ask possible values
GSM to application OK
