programmable xbee with character lcd


I am using a programmable xbee(xb24cz7uisb003-rev_) and have interfaced an lcd with it. I transfer frames using a USB stick that is acting as a coordinator and when the xbee recieves the frame, it displays it on the LCD.

But the problem is, the display on the LCD does not show up if the size of the frame that is transmitted is larger 142 characters. I have no idea why it happens. Is it because of xbee limitations or something wrong with code(which seems to run fine for frame size less than or equal to 142).

Kind Regards,
