I am trying to connect the XBee module to ATmega Uc,
IT seemed easy but got really confusing on the way.
I want it to be connected directly between XBee module and ATmega RX and TX which I did.
Also I want it to be connected to PC RS232 via MAX232. So i can use API and also test it through hyper terminal.
I am confused as it also says need to connect the RTS and DTR pins of XBee to support serial firmware upgrades.
Attached is a basic diagram of what I did and need some help regarding this.
hope to hear from you..
