xbee to xbee communication without MCU help needed.

XBee & XBee Gateway XBee - Zigbee
1

As part of a bigger project I am trying to get 2 of the XBee® ZNet 2.5 (Series 2) modems to interact as follows: Press a button on xbee 1 and LED lights on xbee 2 using pin 20 (D0). Rob Faludi suggests it is doable here:
http://www.faludi.com/2006/12/03/xbee-direct-io-with-adc/

I have each xbee on a separate breadboard without a microcontroller. I have worked through getting them to communicate with one another using the 2-terminal method (typing on one terminal shows output on second terminal). That all works. Before I get too deep here, I would like to ask the very basic question: Is it possible to have 2 stand-alone xbees interact as I described (press button on one causes LED to light on other)?

Here are the contents of the .pro files from XCTU:

Thank you very much for looking.

For such DIO line passing, you should use XBee 802.15.4 (Series 1) Modules.

Hi shahrj,

having the same problem as rob, can I change the firmware
of a series 2 module so as to run as a series 1 module?

As I understand the manual if there is no DIO line passing used or possible,
the data should be put out on the serial port of the destination module.
But that doesn’t work either.

I found descriptions of AT-commands IU/IA/IT which always result in errors.

I would appreciate any answer.

@DWK:

Sorry, there’s no way the series 2 modules can run the firmware for series 1 because the hardware is very different. If you need a feature that’s available on series 1 and not on series 2, you’ll have to use the series 1 modules or find another solution within the supported series 2 features.
