Hi,
I am using the transparent TCP mode to exchange the data, the connection breaks inbetween. I am using the below set of commands to create the connection:
where #013 : \r #10:lf
AT&F#013#10
ATI#013#10
AT+CGMM#013#010
AT+CMEE=2#013#010
AT+CREG=2#013#010
at^sici?#013#010
at^sics=0,contype,gprs0#013#010
at^sics=0,inactto,0#013#010
at^sics=0,user,"user"#013#010
at^sics=0,passwd,"pass"#013#010
at^sics=0,apn,"eseye.com"#013#010
at^sici=?#013#010
AT^SISS=0,srvType,Transparent#013#010
AT^SISS=0,conId,0#013#010
AT^SISS=0,address,"socktcp://:10001;autoconnect=1"#013#010
AT^SISO=0#013#010
AT^SISO=0,1#013#010
AT^SISC=0#013#010
AT^SISH=0#013#010
AT^SISI?#013#010
Can you please help to see if there is any problem with the configurations.
Thank you,
Lakshmi
Hi Lakshmi,
Not sure what is exact issue here, because I see only the configuration and not see when and where the mentioned break comes. Nevertheless I can see that you are missing a key word from the configuration. Please change:
AT^SISS=0,address,"socktcp://:10001;autoconnect=1"#013#010
to
AT^SISS=0,address,"socktcp://listener:10001;autoconnect=1"#013#010
If this will not help, please upload a log when it will be visible where the issue is present.
Best regards,
Michał
