1. Overview
This manual describes the operation of the XBee/XBee-PRO ZB RF module, which
consists of ZigBee firmware loaded onto XBee S2 and S2B hardware, models:
XBEE2, XBEEPRO2 and PRO S2B. The XBee/XBee-PRO ZB RF Modules are
designed to operate within the ZigBee protocol and support the unique needs of
low-cost, low-power wireless sensor networks. The modules require minimal
power and provide reliable delivery of data between remote devices.

The XBee/XBee-PRO ZB firmware release can be installed on XBee ZNet or ZB modules. The XBee ZB firmware is based
on the EmberZNet 3.x ZigBee PRO Feature Set mesh networking stack, while the XBee ZNet 2.5 firmware is based on
Ember's proprietary "designed for ZigBee" mesh stack (EmberZNet 2.5.x). ZB and ZNet 2.5 firmware are similar in
nature, but not over-the-air compatible. Devices running ZNet 2.5 firmware cannot talk to devices running the ZB firm-
ware.

What's New in 2x7x
Firmware
XBee/XBee-PRO ZB firmware includes the following new features (compared with 2x6x):
•Using Ember stack version 3.4.1.
•Support for the PRO S2B with temperature compensation and an overvoltage check. Within 15 seconds of
•Support for the PRO S2B with temperature compensation and an overvoltage check. Within 15 seconds of
the supply voltage exceeding 3.9V, the API will emit a 0x08 modem status (Overvoltage) message, and
then the AT/API versions will do a watchdog reset.
•ZDO pass-through added. If AO=3, then ZDO requests which are not supported by the stack will be

passed out the UART.
•An attempt to send an oversized packet (256+ bytes) will result in a Tx Status message with a status code

of 0x74.

•End devices have two speed polling. 7.5 seconds is the slow rate, which switches to the fast rate to trans-
act with its parent. When transactions are done, it switches back to the slow rate.
•A new receive option bit (0x40) indicates if the packet came from an end device.
•Added extended timeout option since end devices need more time than routers to ack their packets.
•An option bit (0x01) was added to disable APS retries.
•If an end device has not had its polls answered for 5 secs, it will leave and attempt to rejoin the network.
•XBee S2B has a new TP command which returns the temperature compensation sensor reading in units of

Celsius degrees.

•The PP command returns the power dBm setting when PL4 is selected.
•The PO command sets the slow polling rate on end devices. Range is 1-0x1770 in units of 10 msec (10
msec to 60 sec). Default is 0 which invokes a 100 msec delay.
•Rejoining now can proceed without a NR or NRO command after a Mgmt_Leave_req is processed.
•Command ranges were changed for the SC, IR, and LT commands.
•A PAN ID corruption problem was fixed.
