Reset Xbee?

[jdoscher]

I purchased the kit for Tweet-a-watt, and accidentally set my 'reciever' Xbee unit as a transmitter unit. Now it sleeps ever two seconds (like the transmitter should), but I can't seem to find a way to reset the Xbee's configuration. X-CTU gets an error when trying to read/write the configuration. Can someone help me with this?

Thanks in advance.

jerrya posted this a while back and it worked for me.
Digi told me to re-flash the firmware, with the following instructions:
Digi tech support wrote:
- Connect the affective module to an XBIB-R RS232 interface board and the PC leaving the power disconnected
- Launch the X-CTU
- On the PC settings tab, select the proper COM port, baud rate and parity settings
- On the Modem Configuration tab, select the proper modem type, desired function set and firmware version
- Click on Show defaults and Write.
- When the action required box comes up, hold the reset switch in and power on the radio. Release the reset switch and the action required box will close out completing the install
Hope this helps

This worked for me when the reset trick refused to.

It is possible when using the USB board. You just have to go about it in a different manner.
1. Take the module out of the interface board.
2. Connect the interface board to the computer.
3. Open X-CTU
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.

This should get you back up and running.

It can take a couple of tries but it worked for me.

Thanks, but I only have the tweet-a-watt kit, and no developer board. Can it be done with what I have?

[adafruit]

the dev board is the adapter you built. just take a little piece of wire and when it says to reset the board touch it between the GND and RST pin on the adapter. thats why they're right next to each other
may take a few tries...

This did the trick. Thanks!!

The method suggested by Tobrew worked but I discovered that when it failed after writing it was because it had reset the baud rate from 19200 back to 9600. I canceled the message and restarted X-CTU and used the TEST/QUERY function to discover the new baud rate then read the X-BEE and everything seems to work posting.php?mode=reply&f=40&t=11427#

Hello,

I have the same problem with my two Xbee.
The caracteristics of them are :
- Xbee XB24-AUI
- 802-15-4
- 001-rev B

I use one adafruit adapter ( http://www.adafruit.com/index.php?main_page=product_info&cPath=29&products_id=126&zenid=50a0e2b2d9ec4375c42ce270568895bb) with an FTDI 3V3 cable ( http://www.adafruit.com/index.php?main_page=product_info&cPath=33&products_id=70&zenid=50a0e2b2d9ec4375c42ce270568895bb) and the last X-CTU soft.

At the begining, the two Xbee worked well without any bug. I have upgraded them with firmware 10E6 with no problem after this upgrade.

Later, I rewind to them and try to read the firmware and : nothing

The two doesn't answer to any line command or read and write.

The baud rate is 9800-8-N-1.

I try "Tobrew" setting with no success.
I also try with a Reset wiring Reset pin to Ground. ( http://forums.digi.com/support/forum/printthread_thread,243_offset,0)

Nothing !!!!!!!

Here is two screen shoots of X-CTU software.

1. PC Setting



2. Modem Configuration


Do you have an idea ?

Thanks a lot,

it says "Detected Baud Rate Difference"

did you change to different baud rates?

[Richelsdorfite]

Yes,

I try all baud rate from 1200 to 230400.

Perhaps FTDI cable is out ?
I try a serial sniffer all seems good.

[Richelsdorfite]

An other screen shoot with 38400-N-1



I cannot understand why he lost modem communication !

I will try without adafruit shield. As FTDI cable logic level is 3.3 V, I will shunt the SN74AHC.

[Richelsdorfite]

Ok, I try an other FTDI cable.
It's running well.
My two Xbee are OK !

So, I will change my FTDI 3.3V TTL cable.
