There were some significant changes in functionality of the XStream firmware from version 4.25 to 4.29. Here are some of the changes that might affect compatibility:
| Change |
Benefit |
| Time to execute ATWR command (or binary equivalent) |
The non-volatile memory is now double protected against data corruption. This ensures reliable non-volatile storage of all parameters. Command now takes 500ms to execute instead of the previous 100ms or less. |
| Modules contain a unique serial number accessible via AT commands. (ATSH, ATSL). |
Some systems make use of the radio module serial number for system addresses or inventory purposes. |
| Field updateable firmware |
The modules can be reprogrammed with new firmware using PC software provided by Digi. |
| Larger data buffers |
Module can now buffer up to 1000 bytes with no need for flow control. Visit Loopback repeater and buffer sizes for more information on buffer sizes. |
Note: The 900MHz XStream radio is now considered a Legacy product and is no longer available for purchase. The replacement module is the XBee XSC, more information about this radio can be found here: http://www.digi.com/products/wireless-wired-embedded-solutions/zigbee-rf-modules/point-multipoint-rfmodules/xbee-pro-xsc
