What’s New
The XBee/XBee-PRO ZB (S2C) introduces some new features and commands such as:
An alternative serial port is available using SPI slave mode operation
Six firmware images (Coordinator AT, Coordinator API, Router AT, Router API, End Device AT,
and End Device API) are combined into a single firmware
o ATCE command (1-enables/0-disables) Coordinator mode
o ATSM command (0 is Router/Coordinator, nonzero is sleeping End Device)
o Note that Coordinator mode cannot be enabled is SM is nonzero and you can’t set a
nonzero SM if CE is nonzero
Fragmentation is now available in both API mode and transparent mode
P3 (DOUT), P4 (DIN), D8 (SleepRq), and D9 (On-Sleep) are now available for I/O sampling
Both pull-up and pull-down resistors can now be applied to pins configured for inputs
ATVL command added for long version information
ATDO command added for configuring device options
ATAS command added for Active Scan
Self-addressed Tx Status messages return a status code of 0x23
ATDO has HIGH_RAM_CONCENTRATOR and NO_ACK_IO_SAMPLING options added
Binding and Multicasting transmissions are supported
AT&X command added to clear binding and group tables
Added Tx options 0x04 (indirect addressing) and 0x08 (multicast addressing)
A 5 second break will reset the XBee. Then it will boot with default baud settings into command
mode.
BD range increased from 0-7 to 0-0x0A, and nonstandard baud rates are permitted, but not
guaranteed
NI, DN, ND string parameters support upper and lower case
TxOption 0x01 disables retries and route repair. RxOption 0x01 indicates the transmitter
disabled retries.
FR returns 0x00 modem status code instead of 0x01
DC10 - verbose joining mode option
Self-addressed fragmentable messages now return the self-addressed Tx Status code (0x23)
instead of simply success (0x00)
Three command characters ("+++") typed rapidly will shift the device from API mode to AT
command mode
ATCN will shift the device from AT command mode to API mode
