Hi,

I’m using the GE865-Quad.

When I try to store a short message on the SIM card I get the Error SIM busy.

What do I have to do to store the message?

Here is the communication between HOST and GE865:

HOST -> AT&F1<0D>
GE865 -> AT&F1<0D><0D><0A>OK<0D><0A>
HOST -> ATE0<0D>

GE865 -> ATE0<0D><0D><0A>OK<0D><0A>
HOST -> ATE0<0D>
GE865 -> 0D><0A>OK<0D><0A>
HOST -> AT+CPIN="4389"<0D>
GE865 -> <0D><0A>OK<0D><0A>
HOST -> AT+CSCA="+491710760000"<0D>
GE865 -> <0D><0A>OK<0D><0A>
HOST -> AT+CMGF=0<0D>
GE865 -> <0D><0A>OK<0D><0A>

HOST -> AT+CMGW=73<0D>
GE865 -> <0D><0A>+CMS ERROR: 314<0D><0A>

  Is something else that is using the SIM, maybe the registration process? Wait some more time before +CMGW command.

    Now I inserted a 7 second delay but sometimes I still get this error.
    
    Let’s say 90% of the trials are good and 10% still lead to Error 314.

      Is it on a Telit EVK, if not can you try on it? Just to exclude SIM signals problems.

        In this application it is controlled via AVR microcontroller.
        
        I will try on an evk
