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
