|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.
