Q2686 TCP socket reset issue

I amd sending data through Q2686 when i sent the data i am recieving CME ERROR :843 for a particular sequence.

cmd secquence:
at+wipbr=4,6,0
at+wipcreate=
at+wipdata =2,1,2

+CME ERROR 843

Then i have closed the socket and bearer. Then i repeated the same sequence iam getting the same problem. Then changed the module and verified with new module same sequence is sending and no problem observed. How to resolve the issue in the Q2686 chipset.

Are you using different module for this test?
Any difference between the Q2686 and this “new module”?
FW version, WipSoft version?

Have you checked the documentation to see what CME ERROR 843 means?
