I have one more observation on TCP communication, I just wanted to know if it is a bug or design consideration.
In my setup I configured CC3000 as a server and PC application is configured as a client application, when I am sending data from PC application(Client) to CC3000(Server) then in most of the case CC3000 takes 10ms to send the ack for received packet, I verified it using wireshark traces. See the http://e2e.ti.com/support/low_power_rf/f/851/p/302897/1055440.aspx#1055440 for traces, I uploaded trace in this link
It does not matter weather I am sending a 10 byte of data or 1260 byte of data CC3000 most of the times take minimum 10 ms to ack the received packet.
Please share your input on it.
