IoT Modules

Hi, I am using Q2687 GSM MODEM MODULE with AT&T operator. In our application, we don’t want to accept any incoming calls. I am trying to use the CLCK=“AI”,1 command but i am always getting CME ERROR: 3.

AT+CLCK=“AI”,1 Command
+CME ERROR: 3 Response

AT+CLCK=“AI”,2 Command
+CLCK: 0,1+CLCK: 0,2+CLCK: 0, OK Response

2

Using firmware 5.5.24.2, I tried the the below on the my unit connected to vodafone UK.

at+clck=?
+CLCK: (“AO”,“OI”,“AI”,“IR”,“OX”,“AB”,“AG”,“AC”,“PS”,“PN”,“PU”,“PP”,“PC”,“SC”,“FD”)

OK
at+clck=“AI”,2
+CLCK: 0,1

+CLCK: 0,2

+CLCK: 0,4

OK
at+clck=“AI”,1
ERROR
at+cmee=1
OK
at+clck=“AI”,1
+CME ERROR: 16

Assuming your CME error 3 is coming out after a few seconds I would say that there are one of 3 things.

  • The network is not letting you to set the barring up so is not permitted.
  • You need to set the password in the command (you will need to check with them what it is).
  • Update your firmware to the latest greatest.
