XTend firmware revision history

Firmware revision history for the XTend radio modems

XTend version numbers from 2000 on will have 4 significant digits. A version number is reported by ATVR with 4 numbers. All numbers are hexadecimal and can have a range from 0-0xF. A version is reported as "ABCD". Digits AB are the main release number and D is the revision number from the main release if D is 0, it is a major release. "B" is a variant designator. The following variants exist:

• "0" - Normal build
• "1" - Proprietary build
• "2" - Australian build

All releases will have an even number for C. All internal development will have an odd number for C. Field D is always present, even when D is 0.

Version 2.x.6.8

June 2007

• This firmware was only released for Australia version 2268.
  
• Fixed - Allows the correct use of 128 bit Encryption on Australia version firmware.
  

Version 2.0.6.7

May 2007

• Fixed - HT timer expired immediately causing a long header to be sent on every frame

• Fixed - An issue with the XTend getting into a state where it stops transmitting and receiving consistently after 5 to 30 days of continuous testing.
  

Version 2.0.6.4

March 2007

• Added - When doing both API Frames and Repeater Mode, the maximum API frame size is now 256 bytes.
  

Version 2.0.6.1

January 2007

• Added - 128 bit encryption for foreign radios
  
• Fixed - Flow control with packets of 7000 bytes or more and serial baud rate at 115K some data can be lost.

• Added Sniffer mode operation when MK=0.
• Added two retries to the ATWR command.
• Added CD=4 prevents CD assertion unless packet is for that radio.
