Does a zigbee series 2 ( xbee ) module have a inbuilt microcontroller? If yes, is it possible to reprogram that microcontroller? If not, then is it possible to use an external microcontroller.

  • I don't know the particulars, or exactly what you are talking about, but the TI chips that I have looked at, and are the heart of most hobbyist zigbee modules, have a 8051 ip core that you would program over jtag – Grady Player Mar 07 '13 at 04:58
  • why is that , I am getting negative comments ? – hanu Mar 07 '13 at 08:36
  • @hanumesh - I don't know why you are getting downvoted. It seems like a reasonable question. – Rocketmagnet Mar 07 '13 at 11:33
  • how to communicate between xbee S2 and microcontroller without using any software???, (I just want to use my xbee s2,hyperterminal and controller) pls reply me asap… –  Mar 21 '13 at 10:12

The XBee devices do have built-in microcontrollers.

However, Digi does not make a SDK, or the resources required to compile your own firmware image available for the Series-2 XBees.

You could probably theoretically reverse-engineer the modules, and write your own firmware for them. However, judging from the fact that you're asking this question, I think that's a bit over your head at the moment.

  • @thank you !!. I have a two working xbee series 2 modules, one i have set-up as co-ordinator and other as end device using x-CTU tool . Now , i have to connect a sensor to one of the xbee module and transmitt data via zigbee n/w and show the transmission . – hanu Mar 07 '13 at 05:57
  • Unless your sensor has an analog output (and you're willing to live with the crap 10-bit resolution of the XBee ADCs), it sounds like you'll need an additional MCU at each end. – Connor Wolf Mar 07 '13 at 05:59

  • these two links say that it has analog inputs? I am i right – hanu Mar 07 '13 at 06:07
  • @hanumesh - Please re-read the comment I left above: Yes, the XBees have (rather crappy) 10 bit ADCs. If that's good enough for your application, it may work. – Connor Wolf Mar 07 '13 at 17:50
  • Yeah , it supports analog inputs . – hanu Mar 08 '13 at 11:40
  • @ Connor Wolf - I am using zigbee operator tool to setup zigbee network ( http://www.zigbeeoperator.com/index.html ).The co-ordinator is connected to pc ( windows os ) via RS232. Everything works fine but, how do i change the status of end device in a zigbee n/w . Is that,the end device should be connected to some kind of sensors and send information to co-ordinator – hanu Mar 08 '13 at 11:49
