HiI have a problem with GM862 QUAD.When I want to send a SMS, the module returns "+CMS ERROR 331".Please look my tests : AT+CREG? returns 0,3AT+COPS? returns 0,0,"Orange F"SMSC-number is OKLed status is fast blinkingCould anyone help me, please?Best regards
CREG 3 is registration denied. Check the SIM, PIN, antenna etc.
AT+CPIN? returns READYSIM-card works very well with my phone.Antenna is connected and OK..
Is an Orange SIM? What hardware are you using? What firmware version AT+CGMR? Do a network survey AT#CSURV and post the result.
Thank you for your help.
Telit module is connected with a PC. Yes it’s an Orange SIM.
AT+CMGR returns 07.02.605
Please find enclosed the result of AT#CSURV.
please report the result codes of the following commands:
AT+COPS=3,2 then AT+COPS?
AT+CIMI returns 208017701418529
AT+COPS returns 0,2,"20801" after AT+COPS=3,2
AT#SERVINFO returns #SERVINFO: 4,-78,"Orange F","20801",15,5201,00,1,,"II",01,6
If you want to check my schematic, you will find enclosed. All is not represented but the pins connected are they good ?
Pins 6, 8, 43, 27 can be left open if not used ?
in pin8 not used or connected to 5V (CHARGE) ?
Anyway does pins can be left open. An exception can be if you are using CMUX. In this case it is recommended to connect DTR pin (43) to ground.
Could you check also this parameters?
AT+CFUN? it should be 1
AT+CGCLASS? It should be "B"
AT+CGREG? or AT+CGATT?
currently pin8 is not used
AT+CFUN? returns 1
AT+CGCLASS? returns B
AT+CGATT? returns sometimes 0 sometimes 1
now AT+CFUN? returns sometimes 0,2 sometimes 0,3 sometimes 0,5 but never 0,1
the module has a strange behaviour, no ?
The software is up to date ? (07.03.601)
I tested another GM862 and it works fine !
Have you an idea of the problem with my first module ?
Do a firmware reflash in the first module, this will also have a side effect of having all default settings.
Could you send me the latest firmware please ?
Sent to your email inbox, please obtain direct access to Download Zone.
How do I get new firmware, tools and documentation files from Telit?
I’m also getting a similar behavior with the Error 331. Would I please be able to get the latest firmware??
