Hi, I’m a student in a electronics engineering class and on working on a project where we have two XBee S2 of the series XB24-Z7CIT-004 revG. What we are trying to do is: One of the Xbees will work as a master which has a switch connected to one DIO like DIO0 on pin20 and the switch is supplied with 3.3V. [3.3v –\> switch –\> pin20] And the slave Xbee(remote) is connected to a PIC18. So when we push on the switch, the master xbee should send a signal to the slave xbee who sends out a digital high to PIC18. We have been experimenting with different firmwares of XB24-B ZNet 2.5 …coordinator/router/end device/ etc. But with no luck. We have found a lot of examples with the Xbee Series 1 but nothing with Series 2 on the Internet. \*We have been working with this for 2 weeks now with no luck… So it’s simple: 3.3v –\> switch –\> pin20 \*DIO0 (master xbee) – – –\> (slave xbee) \*DIO0 pin20 –\> PIC18 port(RB5) Our present firmware config on the xbees are: \*our PAN 234 and DL and DH is right, cause we can communicate through UART to our PIC18. Xbee master: ZNet 2.5 Coordinator AT 1047 DIO0 - 3 DI (Digital Input) IR - 0 (IO Sampling) IC - FF (Digital IO Change Detection) Xbee slave: ZNet 2.5 Router/End Device AT 1247 DIO0 - 4 DO Low (Digital output, default low \*0V) IR - 0 IC - - Were are we doing it wrong? Can someone here help us? Thanks in advance!
