Hi all,

I am working on a robot that can be controlled by joystick and voice recognition wirelessly. Everything works as expected until I change the arduino board on the receiving end.

Working:

Receiver - Arduino Uno R3,    XBee Series 2 module on Arduino Wireless Shield v2 that is stacked on top of Arduino Uno
Transmitter - Arduino Mega 2560 R3,    EasyVR Arduino Shield stacked on Mega 2560,   XBee Series 2 module on Arduino Wireless Shield v2 stacked on EasyVR Shield

Not Working:

Receiver - Arduino Mega 2560 R3,    XBee Series 2 module on Arduino Wireless Shield v2 that is stacked on top of Mega 2560
Transmitter - Arduino Mega 2560 R3,    EasyVR Arduino Shield stacked on Mega 2560,   XBee Series 2 module on Arduino Wireless Shield v2 stacked on EasyVR Shield


I have run out of digital pins to use for an LCD display that I am incorporating and hence need to change to Mega 2560.

So far, I have reached at a conclusion that the Mega boards are transmitting properly as I can see that from the LEDs on the Wireless Shield but the problem is that they are not receiving properly. I have tried interchanging the Mega boards but that has not helped. As soon as I put the Arduino Uno back everything works normal.

Any help regarding this issue will be appreciated. Thank you in advance for your time and support.
