Question

I have RUT240. How can I disable the PIN code for my SIM cards? I want to use CLI and gsmctl AT commands.

Comments

I have been trying the following commands. Any idea what is wrong with the commands or way to get some further error information?

root@Teltonika-RUT240:~# gsmctl -A AT+CPIN?
+CPIN: READY
root@Teltonika-RUT240:~# gsmctl -A AT+CLCK="SC",O,"1275"
ERROR

 

---

I did try to restart the gsmd-deamon with debug parameters "-D 1"/"-D 5". Unfortunately, I was unable to get some additional information what exactly the “ERROR” is.

Are these AT commands a hardware limitation?

Hello,

the correct AT command format must be:

gsmctl -A 'AT+CLCK="SC",0,"pin code"'

---

I still get message "ERROR" when executing that command with single quotes.

---

Hello,

What error code are you getting?

---

The response is only "ERROR". As I wrote before (May 14), I haven't been able to figure out how to get some more specific error message.

Answer 1

Hello,

our router WebUI does not have the ability to disable the PIN. You can only enter a PIN using the CLI.

I have three SIM cards and don't want to access the WebUI after every change.

Answer 2

Any answer on how to properly remove pin codes (through CLI)?

Answer 3

Some command may have worked anyway. One of my SIM cards had no PIN, when I visited a mobileoperatorshop.

Answer 4

Try these commands

• gsmctl -A AT+CPIN?
• gsmctl -A 'AT+CLCK="SC",0,"PIN CODE",1'

It worked for me.

As you said, that works, also for me too.

The trick is having into account that the full AT command string is passed to gsmctl as a parameter, so any "special" character (spaces, double quotes, etc) must be escaped in order to avoid CLI splitting AT string into several parameters (in the case of spaces), or misinterpreting other special characters.

Two ways of carry out this exist:

• Single quotation of full parameter string;
• Escaping each special character.

Hence, the next command

• gsmctl -A AT+CPIN?    #CORRECT, no spaces or special chars in AT command string
• gsmctl -A AT+CLCK="SC",0,"PIN CODE"   #INCORRECT, doubles quotes are misinterpreted by shell environment
• gsmctl -A 'AT+CLCK="SC",0,"PIN CODE"'  #CORRECT, full AT command string is single quoted
• gsmctl -A AT+CLCK=\"SC\",0,\"PIN CODE\"  #CORRECT, each special char in AT command string is escaped
