[Tinyos-help] CC2420 Hardware ACKs

Hi all,

I was trying to set Hardware ACKs for CC2420 radio chip. I did a simple
ping pong application in which I posted a task call ack() inside the
event SplitControl.startDone(error_t error). 

The task call ack activates HW acknowledgements in the following way:

bool activated = TRUE;
task void ack() {
      call CC2420Config.setAutoAck(activated,activated);
      if (call CC2420Config.sync() != SUCCESS) {
          post ack();

However, the mote that is sending messages is not receiving any ack.
Should I do anything else to activate CC2420 HW acks?. Any help?
