Does anybody ever seen a problem where recv API hangs after working for some time :
In our send API is working fine and the application running on PC(Connected to access point) is receiving a data properly but when I start doing transmission from PC application to CC3000, initiially it starts working fine and receives the data but after receiving few bytes (Range from 1- 100 bytes)it hangs in SimpleLinkWaitData function.
I tried to configure CC3000 to server as well as client but in both the case end result is same.
I have seen one more thing that till the time CC3000 device is receiving data properly and in this duration if I send a ping command from PC to CC3000 then it works smoothly but once CC3000 stop receiving a data then ping operation failed to complete.
I also use the setsockopt api to make recv function call non blocking when I configure CC3000 as a client but that does not help me to avoid frozen state of recv API call.
I am also attaching a source code, see if some one can trace anything wrong in it.
