please suggest the solution for the issue.

hi,sandesh.h
QISENDEX is used to send hexadecimal string data. If you are sending data that is not a hexadecimal string data, I recommend using the QISEND at command.

Hi

I am sending the hexadecimal data only. So i went with AT+SENDEX.
And with AT+SEND also i am getting ERROR.

AT+QIOPEN=2,2,“TCP”,“2402:3a80:170a:601:d9cf:bf5d:13f0:801b”,60000,0,1

OK

+QIOPEN: 2,0
AT+QISTATE?

+QISTATE: 1,“TCP LISTENER”,“2402:3A80:170A:602:0:55:7575:2201”,0,6000,3,1,1,0,“uart1”

With this also i am facing the same issue.

hi,sandesh.h
This error indicates that the connection is not established, abnormal disconnection, or incorrect parameters.
I pinged your server address to test that it is abnormal.
I suggest you check that your TCP server is working properly;Or tomorrow I can provide our TCP server for you to test.
