If you fool around with Bees, you will eventually brick one!. I did, but fixed it differently than most on-line instructions.
The forced boot-loader, and RST ploys both failed in my case. But since I've messed with computers enough, (back to CPM) I figured it like this. Since I have two, they must be identical to communicate, if the same model. Since mine pretty much worked out of the box, I had simply changed the baud rate to 56700, which seems to be as fast as the model I have (XPB9B-XC) wants to run. I determined this buy using X-CTU and then Read in Modem Configuration, which displays a drop-down list of "modem parameters" (X-CTU uses the word "modem" like cops use the word "vehicle").
In the drop-down, under "Serial Interfacing BD" .... the maximum speed offered is 57600. (works at this speed OK. BTW) But since I wanted to run at 115200 for APM, and couldn't with that profile (XPB9B-XC) I had tried to load another profile and......... Ka-blooy.. brick city! (green light OFF)
I tried most of the most of the posted remedies but none seemed to work. Then, figuring out I had two with one working, I plugged in the good one and did a READ command which loaded it's firmware into memory. I then, without unplugging the AdaFruit carrier from the SparkFun 3.3v/5v FTDI Basic interface and I plugged in the other (sick) XBee (already) in a similar AdaFruit carrier and hit the WRITE button in Modem Configuration menu on X-CTU, and it now is working. Kinda like copying a floppy? Just copied one's firmware into the other.
I haven't tried anything but both in a terminal (mode) conversation, but they are talking to each other again. Happy ending!
Step by Step
Two XPB9B-XC XBees 900mhz
I have each Xbee in it's own AdaFruit Xbee Adapter board.
I am using the SparkFun 3.3v/5v FTDI Basic USB interface which plugs into the AdaFruit adapter.
X-CTU program software from DIGI.com
FTDI driver for Windows from DIGI.com's link to drivers download site
1- Plug in USB with SparkFun FTDI attached to Adafruit containg the working XBee.. and USB cable into com port
2- Start X-CTU program then select "PC Settings" tab and set baud rate. (start at 9600 unless...)
3- Confirm operation using Test/Query. You must get through this step which shows read operation works OK.
4- Select "Modem Configuration" tab
5- click "READ". This loads working unit's firmware into memory. (If it doesn't display the parameters list in a dropdown then the rest probably will not get it working.) If it does, though, continue!
6- without doing anything else, unplug AdaFruit carrier from Sparkfun adapter.
7- Now, plug in non-working Xbee mounted in it's own Adafruit carrier into the still-connected-to-the-computer Sparkfun adapter.
8- Click "WRITE"
9- Adafruit green diode should come on indicating Xbee working.
10- test by starting a second copy of X-CTL (use different port, correct baud rate) then select "TERMINAL" tab
11 Move cursor to text area and type a few keys: If the XBees can now talk to each other, you fixed it.
I hope this brief entry helps some other poor slob who Bricked-His-Bee! (BHB) - It's now 4:20!
