Hi Team,
I created TCP socket connection to a TCP Server. Next SSL handshake is intiated. Client has sent Hello msg and TCP Server replied with Hello msg, Cipher suite and Certificate. TCP Server sends this reply in multiple messages to TCP client - This has been verified in Wireshark logs.
But ESP8266 acting as TCP Client is not sending any +IPD messages to my application.
Following are the commands sent to ESP8266 from my application:
AT\r\n
\r\nOK\r\n
AT+GMR\r\n
AT version:1.2.0.0(JuL 1 2016 20:04:45)\r\n
SDK version:1.5.4.1(39cb9a32)\r\n

** Here Expected is +IPD msg. Since no msg was recieved, application closed the socket **

Is there anything needs to be done to get +IPD msg OR is it issue with ESP8266 in handling multiple TCP packets at a time?
Please let me know how to proceed with this issue?
Thanks in advance!
