TCP Channel closure resource

Hello all,

OS Firmware 7.2
WIP Plugin

I am using the wip_TCPClientCreateOpts function to create a TCP channel over GPRS, I am utilising the WIP_COPT_FINALIZER call back to tell me when the channel has been closed. To close this channel I am using the wip_close function.

I believe I am getting into a situation whereby the closed channel has not been closed properly by the server side leaving the connection in the device in a FIN_WAIT_2 state.


  • How long does this state remain for in the device and is this time
    configurable, and,

  • After processing the WIP_COPT_FINALIZER routine I would like to
    know if it is at all possible to determine if all resources for that closed
    channel have been released. Is this possible, if so how?
