3/15/2007 : RadioBackoff and Address Recognition

  • Removed hardware address recognition. This forces the radio to download every packet, which takes time. The time spent downloading a packet to non-destination nodes should improve acknowledgment success rate.
  • Parameterized the RadioBackoff interface at the top of the radio stack instead of in CsmaP, to make it easier to implement alternative implementations of the CC2420 stack.


2/4/2007 : SendNotifier

  • Provide the SendNotifier interface in CC2420ActiveMessageC to support CTP + LPL integration


1/17/2007 : LQI / RSSI

  • An edge case was found in CC2420ReceiveP where the LQI and/or RSSI values can be corrupted for packets using TOSH_DATA_LENGTH and (TOSH_DATA_LENGTH - 1) length payloads.
