Builtin LED blink 2

Hello ALl,

Asked sometime back on this subject,and had some replys from some nice members albeit none really worked in the end.
Am wanting to have the builtin LED on the rtlduino boards, blink after making a successful connection to the target AP. Am using the ‘example_wlan_repeater’ setup that works perfect for my project, For convience as this is a X2 units, one rtlduino on drone to act as a 'sender/repeater, that connects to drone,then a second rtlduino on ground that connects to the drone repeater. Have increased the drone’s FPV range dramatically with this setup,but am missing a piece and am not smart enough to figure out code to make the LED blink,as i am explaining here.

Thanks
