Hi,
I have several questions about Acks for CC2420 in Tinyos 2.1.0. 1. In the CC2420ControlP.nc, it seems that autoAck is enabled by default, but why I cannot get ack at all by calling PacketAcknowledgements.wasAcked(message_t* p_msg)? 2. Then I tried to call CC2420Config.setAutoAck(TRUE, TRUE) and CC2420Config.sync() to enable autoAck by hand, but still not successful by calling PacketAcknowledgements.wasAcked(message_t* p_msg). 3. Finally, I have to add PacketAcknowledgements.requestAck(&pkt) before calling send, then I can have Acks from PacketAcknowledgements.wasAcked(message_t* p_msg). Is there anything wrong in my first two steps? Do I have to call Acks.requestAck(&pkt) in order to have my Acks? Thanks, Jason
