XBee®/XBee‐PRO® ZB SMT RF Modules
Firmware Updates
Wired Updates
A user can update their application using the bootloader in a wired configuration with the following
steps:
a. Plug XBee programmable module into a suitable serial port on a PC.
b. Open a hyperterminal (or similar dumb terminal application) session with 9600 baud, no parity,
and 8 data bits with one stop bit.
c. Hit Enter to display the bootloader menu.
d. Hit the "F" key to initiate a wired firmware update.
e. A series of "C" characters Will be displayed within the hyperterminal window. At this point,
select the "transfer->send file" menu item. Select the desired flat binary output file. (The file
should start at 0x8400 not 0x0000).
f. Select "Xmodem" as the protocol.
g. Click "Send" on the "Send File" dialog. The file will be downloaded to the XBee Programmable
module. Upon a successful update, the bootloader will jump to the newly loaded application.
Over-The-Air updates
A user can update their application using the bootloader in an "over-the-air" configuration with the
following steps:
(This procedure assumes that the bootloader is running and not the application. The EM357 baud rate
must be set to 9600 baud. The bootloader only operates at 9600 baud. The application must be
programmed with some way to support returning to the bootloader in order to support Over-the-Air
(OTA) updates without local intervention.)
a. The XBee module sending the file OTA (Host module) should be set up with a series 2 Xbee
module with transparent mode firmware.
b. The XBee Programmable module receiving the update (remote module) is configured with API
mode enabled.
c. Open a hyperterminal session to the host module with 9600 baud, no parity, no hardware flow
control, 8 data bits and 1 stop bit.
d.Enter 3 pluses "+++" to place the EM357 in command mode.
e. Set the Host Module destination address to the target module’s 64-bit address that the host
module will update (ATDH aabbccdd, ATDL eeffgghh, ATCN, where aabbccddeeffgghh is the hexa-
decimal 64-bit address of the target module).
f. Hit Enter and the bootloader command menu will be displayed from the remote module. (Note
that the option "B" doesn't exist for OTA)
g. Hit the "F" key to cause the remote module to request the new firmware file over-the-air.
h. The host module will begin receiving "C" characters indicating that the remote module is
requesting an Xmodem CRC transfer. Using X-CTU or another terminal program, select "XMODEM"
file transfer. Select the Binary file to upload/transfer. Click Send to start the transfer. At the con-
clusion of a successful transfer, the bootloader will jump to the newly loaded application.
Output File Configuration
BKGD Programming
P&E Micro provides a background debug tool that allows flashing applications on the MC9S08QE parts
through their background debug mode port. By default, the Codewarrior tool produces an "ABS"
output file for use in programming parts through the background debug interface. The programmable
XBee from the factory has the BKGD debugging capability disabled. In order to debug, a bootloader
with the debug interface enabled needs to be loaded on the secondary processor or a stand-alone app
needs to be loaded.
