Step 5: Un bricking a frozen Xbee.

Alright, so the sort of disclaimer on this whole Instructable is that you may freeze up you Xbee during the update process when changing settings, and modifying the xbee via XCTU. Don't worry, it is rare. But if you happen to run into this dead xbee situation here are the steps to try before ripping some hair out, and declaring your Xbee's time of death. 

These steps we contributed by Cristof. Thanks to him, we have a solid step by step run down on how to attempt a fix.

1. Take the module out of the interface board.
2. Connect the interface board to the computer.
3. Open X-CTU make sure Baud Rate is set to 9600
4. Go to "Modem Configuration"
5. Put a check in the "Always update firmware" box
6. Select proper modem from drop down menu,
7. Select proper function set and firmware version
from drop down menus.
8. Click on the "Write" button. After a few seconds of
trying to read the modem, you will get an Info box
that says Action Needed. At this point, CAREFULLY
insert the module into the interface board.
9. You may get the info box again a short while after,
just use the reset button on the interface board.
Update: Well after letting this instructable soak for a while, some comments brought a missing piece to my attention. If you are working with an Xbee Explorer board that does not have a reset button, you can not complete the process. That won't do, so we have come up with a simple fix for you. Take a wire to jump a connection between RST, and GND. When it comes to the point that you need to reset (Hint this will work any time you need to reset.) just jump the two pins together, and you have reset the device! Good Luck friends.

Update 8/23 Thanks to reader kolment2003 a great recommendation to use a bread board, to switch for the Reset to Ground. This will allow a solid connection, and a reliable reset when you need it. Thanks  kolment2003

<p>Hello </p><p>im trying to connect zbee pro 900 ( xbp09-dpsit-156) through USB cable using XCTU software but it gives me error ( modem not connected ) , i checked the power and nothing bad , the xbee explorer is working . <br>so i hope someone will helps me solving this problem . <br><br>best regards , <br>Ahmad Kalbouneh</p>
<p>You can buy an XBee USB adapter compatible with the XBee USB explorer for an even better price from this website: <a href="https://www.openimpulse.com/blog/products-page/product-category/xbee-usb-adapter-module/" rel="nofollow">https://www.openimpulse.com/blog/products-page/product-category/xbee-usb-adapter-module/</a></p>
<p>Hello! Thanks for explaining how to deal with Xbee modules ;)</p><p>You can buy a good Xbee USB adapter (that looks like the sparkfun one) for a good price on this website: <a href="http://voltatek.com/en/communication/103-xbee-usb-adapter.html" rel="nofollow">http://voltatek.com/en/communication/103-xbee-usb-...</a></p>
I ran into an oddity... I managed to port Hyperterm over to Windows 7, only to have x64 Win-7 balk that it is not a compatible program... There were a few others out there, RealTerm, which promptly crashed once it fired up. One I found, that's semi-fool proof, Putty.. this is a multi-purpose shell terminal, either ssh or serial. In the serial mode, it's very rudimentary, you must remember what the serial port the usb Explorer, or ftdi cable are connected to, and manually set the baud rate. But, it runs very much like a standard serial terminal when selected. Element-14 contributor Jeremy Blum gets kudos for mentioning it. I've used it for serial and ssh access to microcontrollers and a home server, incase things go awry.
I dun have the USB explorer board! can I use the rs232 module to unbrick my xbee??!!??
If you're using a version of X-CTU that talks to it via the RS-232, read the note above by kolment2003, which I just replied to. It should work the same, addint a momentary contact switch between pins 5 &amp; 11, but only when X-CTU is in the middle of attempting to re-write the firmware, and failing.. the most recent version pops-up with a info window saying no response, yada.. yada.. yada.. then at the bottom: XBEE: Press and release the reset switch, info window will close...... might work? <br>
Fixing Bricked Xbee 2.5 while using a usb explorer 1- solder some headers into the usb explorer to be able to attach on a breadboard 2- short out GND and RST with a switch ( just like the one for reset on arduino) 3- when asked to reset the xbee , short out GND and RST with the switch PS: i was never able to properly reset by just shorting the pins with a wire, but with a breadboard n a switch it works like a charm!!!!!!!
I just found this out myself after accidentally writing the wrong firmware to a S1.. Followed the instructions on a google page, but it still stayed unresponsive, short of the &quot;do this...&quot; window from X-CTU.. Then, I read the line.. press the reset.. But, the carriers from parallax or Adafruit don't have a reset button.. THEN it dawned on me, the pins (pin 5 &amp; 11) as you said. As soon as I pressed the button on the breadboard, the info window closed, and X-CTU responded with writing firmware.. Now, the fun part for me.. learning the differences between the Series-1 (XB24 805.12.4 (?)) and the Series 2 (Not S2, XB24B)
Hi, Thanks so much for the input! That is valuable information. I will make some modifications to the Instructable to reflect this. Credit given of course. ;) Thanks for reading, and again thanks for the input.
I had a bricked XBee module. I &quot;bricked&quot; it the first day that I received it!! The same day that I started working with XBee's!!! This tutorial helped me fix my problem!!!! Thank you sooooo much. It's wonderful to have &quot;people in the know&quot; like your self ,that will try to help beginners!!! Thanks again!!!
This works like a champ in every carrier I have tried it with. No wires, no buttons, no fuss. One of those &quot;ahah&quot; moments. Wish I had thought of it
To un-Brick:<br><br>OK, I tried your UNBRICK technique and it worked once for me, but I did my mistake again and I could not get it back. I looked for a good long time and found the following. It even worked with my non-Digi usb board from Parallax... <br><br>It uses the X-CTU program and signals the module using break on the terminal window - you have to use the wire-to-reset trick, but it works!<br><br>http://www.digi.com/wiki/developer/index.php/Bootloader_to_force_XBee_reflash
Hi,<br>I've bought two Xbee-PRO XSC with two XBee Explorer Regulated boards and a FTDI cable from sparkfun store.<br>I've tried to use them many times, but they don't work.<br><br>I've tried to manage them by X-CTU, Xbee module has been connect using sparkfun XBee Explorer Regulated board and FTDI usb cable. Parameters has been set to 9600 8-N-1 FLOW:NONE, API enabled, no baud change. <br>The test result has been &quot;Comunication with modem..OK Modem type = Name unknown (ID = 42949672481228316) Modem firmware version= &quot;<br>I've tried to disconnect the module or change it and the result has been always the same!<br>I've tried to update firmware by following your instruction, but X-CTU returned always the same sentence &quot;Getting modem type....OK<br>Programming modem...Lost communication with modem<br>Write Parameters...Failed&quot;.<br>If I disable the API function and update, the Action Required windows appeared. I followed the instruction by resetting the module (pin5+ground) and the following sentence appeared: &quot;Getting modem type....OK<br>Programming modem...Detected baud rate difference.<br>Make sure PC and modem baud rate is set correctly<br>Lost communication with modem<br>Write Parameters...Failed&quot;.<br>I've tried also by using &quot;GUI serial Xbee3&quot; for MAC OS, but neither it worked.<br>I've tried all the solution I found in internet, but they did not work. What I have to do?<br>Have I to use a XBee Explorer USB board instead of XBee Explorer Regulated board? Is it a problem of Vcc?<br>Thanks, Giuseppe.
hi, I can sent data but still can't receive it (Minimum connections: VCC, GND, DOUT &amp; DIN with micro contololer) my xbee doesn't receive, led of dout doesn't any act.
have you tried using the dongle with an xbee pro? the way i understood your tutorial, u simply used the dongle to program the xbee right?
thanks for the help i couldnt get either of the xbee to connect
I tried everything but still can't &quot;communicate with modem&quot;. I have a pair of Xbee 24s and I've tried resetting, connecting piggyback to an arduino to give me the reset ability. I changed usb cables and swapped between the explorer module and the prototyping unit. Nothing seems to work. <br>It also comes up with a message saying the baud rate is different between modem and pc and then looses connection to the modem. I've triple checked the baude rates and retried but no luck. <br>Next????? <br> <br>Stephen <br> <br>
