Transmit Receive data on Wi9c WLAN

Hi,
I just recieved connect 2x core wi9c jumpstart kit . I am a novice in C.

  1. Want to transmit a data of any length to the other board via wireless link.
  2. retrieve the data from the other board?
  3. Which functions in the API to use? wln_send() i cant figure out how to set the right format for it to accept data.
  4. How to retrieve the data from receiveing end, how would i know that it had recieved data from this board?

Please give me some pointers since i am lost for a week now.
Kind regards
sam
