                                      Version 8072
================================================================================


INTRODUCTION
  These release notes document changes made to the 80kbps firmware on the XBee 
  865/868LP radios.


ENHANCEMENTS
  - Added the ATN? command which returns the timeout for the Network Discovery 
    (ND) and Discover Node (DN) commands.


BUG FIXES
 - LBT DigiMesh fixes.

 - Fixed a problem with voltage and temperature reading. This could potentially 
   affect RF performance as well as the AT%V and ATTP commands.

 - Fixed an encryption bug, where under heavy load the incorrect key was used.

 - Fixed an issue with the Associate LED which was off during a 30 second wakeup 
   initiated by a single commissioning button press.

 - Fixed an issue that caused the node to lock up when directed broadcasts were 
   forwarded.

 - Fixed bug where ST was being changed on power cycle when in SM = 7.

 - The Associate LED was off during ATCB1 - 30 second wake from synchronous
   sleep.

 - Synchronous Sleep: Associate LED erroneously blinked when the network was
   asleep.

 - SPI/UART: Holding DOUT low while resetting did not cause module to enter SPI
   mode.

 - Fixed reliability issue with the Indirect Message Unrequested Tx Status 

 - Fixed bug where the packetization didn't work correctly when RO=0 and BD<4.

 - Fixed bug where GPM erase commands caused a reset.

 - Fixed bug where baud rates 9600 and below had inaccurate bit timing (although 
   the overall baud rate was usually accurate).

 - Fixed SleepingRouter bug where sync messages were unreliably relayed when
   BH=0.

 - Fixed bug where a module with a full TxBuffer (held off by RTS) would not go
   to sleep.

 - Fixed bug where Aggregate Addressing (AG) command was not working properly.


KNOWN LIMITATIONS
 - No SPI data should be transmitted or received while an ATWR is in progress. 
   Data could be lost.

 - When the ATRO parameter is set to 0, occasionally data will not be sent 
   over-the-air until more characters are received serially. This setting
   should not be used.

 - The serial port is non-responsive for approximately 70ms after a baud 
   rate (ATBR) change is applied either by the ATAC command or by exiting 
   command mode. To work around this issue the user should insert a 100ms
   delay after applying a baud rate change.


HISTORY
  Version 8059 (Initial Release)
    KNOWN LIMITATIONS
      - Setting the ATIR parameter to sample faster than the module can transmit
        the samples will cause the module to not sleep when using ATSM4.

      - When sending a directed broadcast (0x80 on tx option), the transmit 
        status frame will always indicate that a route discovery has taken place,
        (discovery status byte = 0x02).
