7 Security commands
7.1 Enter PIN +CPIN
Description :
This command is used to enter the ME passwords (CHV1 / PUK1), that are required before any ME
functionality can be used.
CHV1 is between 4 and 8 digits long, PUK1 is only 8 digits long.
The application is responsible for checking the PIN after each reset or power on
- if the PIN was enabled.
Syntax :
Command syntax: AT+CPIN=<pin>
Command
Possible responses
AT+CPIN=1234

Note : Enter PIN
+CME ERROR : 3
Note : Operation not allowed, PIN previously
entered
After 3 unsuccessful attempts to enter the PIN (Personal Identification Number), the PUK (Personal
Unblocking Key) will be required. PUK validation forces the user to enter a new PIN code as a second
parameter and this will be the new PIN code if PUK validation succeeds. CHV1 is then enabled if PUK1
is correct. The application therefore uses this command: AT+CPIN=<Puk>,<NewPin>
