Hi,

Working on my first project. I need assistance with interfacing two PICSs 16F877 wireless using Xbee PRO. These PICs communicate just fine when wired directly between them however, when using the Xbees (in transparent mode) I do not get them to communicate. The Xbee connections are: 3.3V on pin 1, GND on pin 10, Din (on pin 3 of Xmitter) and Dout (on pin 2 of Rcvr). I noticed that the 3.3 V power source drops to 3.0V when the Xbees are connected.

These Xbees work fine together when used to establish communication between two computers using sparkfun Xbee Explorer boards.

Need ideas on what do to resolve this wireless communication issue. I can provide more details...
