Cliff,

It seems that enabling the pull up resistors stops the bee from working permanantly, despite the fact that these are indeed on sparkfun boards!

I've just spent 3 hours after enabling pull up and can't get a squeak out of either even with settings that have worked, so this looks like an unpredictable action. Both are showing data received from the serial interface, but niether transmit anything. I've tried disabling the resistors first, updating the firmware and everything else I can think of and nothing.

Hi,

Well after lots of searching there is a way to unbrick your xbee, it's to

1 unplug the bee from the usb adaptor

2 plug the usb adaptor into the computer

3 start the software go to configure modem

4 tick the always update firmware box

5 CAREFULLY insert bee into usb adaptor and it updates and recovers.

Now I'm back to 2 bees talking!

Well, Well!!

For 2.4 XBEE Pro S2B on Sparkfun adaptors only.

After searching for hours and hours the soloution seems to bee :-

Always read the settings before you change something so that only the bits you want are changed.

Always start the sequence by loading the defaults into X-CTU

Always read back the settings after you change something.

1 use the config XBP24BZ7 settings both ends 1 is Coordinator AT the other is Router AT use the default baud 9600.

2 do these steps for both units

3 read back the settings so that you can see  serial number high and low, write them into notepad

4 set the pan id to something you want.

5 do 3 to 4 again for second unit

6 for both set the destination high and low to the serial number high and low of the other unit.

7 now just change the baud to 57600 and remember to change pc settings to the new baud rate

If this does not work I don't know!! but it's taken a week to find this out. XBEE'S are great!!! (now).

Thanks to the people who replied.

http://diydrones.com/forum/topics/xbee-adaptore-wont-talk-to-xbee-m...

I have a new Xbee pro adapter from Jdrones I am having trouble to work withe the Xbee pro 90 XBPO9-DP module.

I know its not the module that is the issue because I have another adapter that the module works fine with. I have tried both the baud 57600 and the 9600 but I always get the popup instruction to push the rested button. Ive tried the reset using a jumper to connect the GRD and RESET on the adapter board but nothing happens.

I have followed the instruction above here how to reset/unbrick the adapter and module to reset the firmware. Nothing works.

I am using the FDTI cable. When I plug this in I get a blue LED on right top side of the adapter that lights up which seems normal compared to my working Xbees. When I open X-CTU and click Test/Query a green LED to the top left of the adapter blinks for a few seconds and then goes solid green when the "Action Required" box pops up. That's as far as I can get it to go.

Ive tried to upload the firmware from my other Xbees, but nothing works because the X-CTU cant communicate with this adapter. Any idea why this isn't working and how to reset the adapter (not the module)? Note, this all works fine using the FTDI cable on my other two Xbees.
