I had thought of that,but if it was blinking fast (with 50% duty cycle).. I should have been able to see it (persistance of vision :)) ! I did try your valuable suggestion and it seems that as long as cnt==x where x <=4 the green light is toggled, other wise for cnt > 4 it isnt. It seems as if it is just rtansmitting the address, or if it is tranmmiting anything more.. It doesnt seem to cause the event to be triggered after the address fld has been transmitted. (I set the address to TOS_BCAST_ADDR before sending).
Thanks for your help.

And it is triggered for every byte of data received. Have you tried: if (cnt == 8) { call Leds.greenToggle(); } that's the quick way to figure it out. -Joe On Sun, 20 Feb 2005 20:49:22 -0800, Affan, Syed <[EMAIL PROTECTED]> wrote: > Hello, > I am trying to use the RadioCoordinator interface implemented by > CC1000RadioIntM, to get information when the first few bytes of my msg > structure have been sent and then proceed with some actuation.
