xbee cannot send data when serial monitor is not active...

Hi…

i have arduino leonardo using xbee to wireless communication (xbee)…
i have a problem when i use the serial monitor on Arduino IDE, the communication between two Xbee is normal. but when i use battery /powerbank or serial monitor on arduino IDE is inactive, two xbee cannot communicating each other…

i hope the problem will be solved…
