Xbee and at89s51

[Amogh Arun Marathe]

 

Our project has simple task of sending some text from the laptop(one end) to the microcontroller(other end).

We need to establish a wireless network between the laptop and microcontroller. 

We have :two series2 XBees; two Xbee breakout boards (one with USB and another with DB9 port); microcontroller. 

We want to interface one Xbee with an at89s51 microcontroller. C

an anyone please guide us in interfacing these two?

do we need to use a level-shifter at the tx-rx pins of xbee?

Kindly help.

1. You have to download X-CTU  from Digi’s website to configure ur Xbee

2. Write one’s SH and SL  addresses in DH and DL address of another Xbee then program ur Xbee

3. Check the interface using ur laptop and computer..

After configuring ur Xbee u can connect it with ur microcontroller, although u don’t require a level shifter but if u use MAX 232 to inetrface through Xbee board it will be Good…

but xbee works only on 3.3 volt supply. then how we can connect directly xbee to arduino or microcontroller.
