BGS2T: Cant open service (CME ERROR: network is down) | Telit Cinterion IoT Developer Community
August 30, 2016 - 2:07pm, 6806 views
Hy all,
I have a BGS2T module connected via RS-485 with my PC and i want to transfer data to a ftp server.
My config is:
AT+CMEE = 2
AT^SICS=0, conType,GPRS0
AT^SICS=0,user,"*****"
AT^SICS=0,passwd, "*****"
AT^SICS=0,apn,"****"
AT^SISS=1,srvType,ftp
AT^SISS=1,conId,0
AT^SISS=1,address,"********"
---------------------------------------
Up to this point there are no errors.
AT+CREG? answers: +CREG: 0,1
AT^SISI? answers ^SISI: 1,2,0,0,0,0
AT+CREG? answers: +CREG: 0,1
AT+CPIN? answers: +CPIN: READY
AT+COPS? answers: +COPS: 0,0,"myoperator"
AT+CGREG? answers: +CGREG: 0,1
AT+CGACT? answers: +CGACT: 1,1
AT+CGPADDR= 1 answers: +CGPADDR: 1,"xx.xx.***.xx"
Therefore i think that I am registered to my network.
Everytime when I type AT^SISO=1 I get this response:
+CME ERROR: network is down
Whats my failure?
Thanks in advance!

^SICI: 2,0,0,"0.0.0.0"
^SICI: 3,0,0,"0.0.0.0"
^SICI: 4,0,0,"0.0.0.0"

AT^SISI?
^SISI: 1,4,0,0,0,0
OK
------------------------------
Everythoing is fine now!
Thanks for your help!
Hi,
for this mesagge is produced for:
-No network, or weak signal
-The SIM card is not provisioned for GPRS
-the used user or/and password contains a specila character like !,@,etc . In this case the the parameter
"alphabet" in the at^SICS definition.
----------------
"alphabet" Selects the character set for input and output of string parameters within a profile.
The selected value is bound to the specific profile.
This means that different profiles may use different alphabets. Unlike other parameters the alphabet can be changed no matter whether the <conParmTag> value "conType" has been set.
For supported values of <conParmValue> refer to <conParmValue-alphabet>.
--------
Try to set up "alphabet" to 1.
"1" International Reference Alphabet (***, seven bit ASCII) applies.

Hy,
the alphabet was my failure. The username of my config profile contains an '@'.
The problem was that i have expected an error after entering the username if the string is invalid.
Thanks a lot!
I have an unstable bug with BGS2.
Initialization for FTP connection look like below:
AT^SCFG="Tcp/WithURCs","on"
^SCFG: "Tcp/WithURCs","on"
OK
AT^SICS=0,conType,GPRS0
OK
AT^SICS=0,user,gdata
OK
AT^SICS=0,passwd,gdata
OK
AT^SICS=0,apn,internet
OK
AT^SICS=0,inactTO,90
OK
AT^SISS=0,srvType,"Ftp"
OK
AT^SISS=0,conId,0
OK
---------------------------------------------------------------------
Tnen i send:
OK
AT^SISS=0,address,"ftpput://my_username:my_password\0011.222.333.444/my_path/my_filename.log"
OK
AT^SISO=0
<0>
OK
+CREG: 2
The <0> is NULL character in my terminal program, and +CREG: 2 is lost of net registration. At first I thought that for some reasons undervoltage case after SISO command. I checked with an oscilloscope 3,7 V power supply, but don't see down pulse at power line.
In some cases after SISO command after delay around 5 sec. i get ERROR message.
AT^SISO=0
ERROR
And in some cases after SISO command i receive and see in terminal program:
AT^SISO=0
<0><0> ^SYSSTART
Hello,
Are you using a hardware of tour design? Maybe there is some problem with it. Are both BATT+ lines connected and all according to Hardware Interface Description document?
Please enter AT+CMEE=2 to see more descriptive error replies.
Have you tried to send SMS or establish a call to test the stability of the HW?
Regards,
Bartłomiej
Both lines at PCB trace to pins #5 and #53, but i 'm not sure in good soldering at pin #53. I'll try to resold. When i set AT+CMEE=2, imp is hid. :-)
SMS sending is always stable.
Hello,
Please let us know about the results.
Please also try a voice call or other internet service. And check the signal quality - maybe the network coverage is bad or you have the problem with antenna. But this reset would rather suggest some hardware problem.
Please check the firmware version with ATI1.
Regards,
Bartłomiej
