XBEE no longer comunicates

I,m currently using an Xbee Explorer USB board with a “802.15.4” XBee (Series 1) connected into it. I was trying to do a firmware update and it seemed to work but then I received a message saying something about unable to communicate with the modem.

My baud settings are all correct so I know there is no issue there. Iv also got 2 other Xbee’s same series sitting here that both work like there supposed to and have the latest firmware.

I found some posts where people mentioned holding down a reset switch and writing firmware, but there is no reset switch on the explorer board that I can see. Someone else mentioned writing the AT mode software to the device and then resting and all was good. Problem is I have no idea how to do that.

Any ideas on how to reset it would be much appreciated I’m pretty puzzled where to go from here.

No doubt you know that when you update the firmware you also alter the baud rate settings, often to 1200 or 9600 baud. Also, note the baud rate displayed in the bottom of the main window where you click on the Test button.

I did find, recently, that an XBee did accept a flash load but refused to respond later to AT commands no matter the baud rates. The odd cure for this was to use the XBee development board with RS232 and flash version 10CD (if I recall correctly) and for some reason that started working.

Digi tech support does have some non-obvious methods to recover a bricked XBee.

Yeah there are def some less then obvious ways to do this apparently.

But I have fixed my problem.

The way I did it was by hitting read in the Modem Configuration tab. This gave me an error that I hit cancel to. Bellow that were several messages one of which was.

If read problem continues select modem type and ‘Always update firmware’ from controls above and click on ‘Write’ to force firmware update.

I did this using the Explorer Board and they are now all flashed with the latest 10CD firmware.
