Problem in uploading program to the board when connecting Zigbee

I use arduino uno for my project. I have a problem in uploading program to the board only when I connect the zigbee. I'm getting the error message as
avrdude: stk500_getsync(): not in sync: resp=0x00
please help

Thank you

Which zigbee? Which shield? How is the zigbee connected to the Arduino?

I suspect your zigbee is using the RX/TX pins.


I connected using the tx and rx pins only. But i bypassed the chip by connecting reset to ground and hence the problem occurred :stuck_out_tongue: . It's working fine now. Thank you..
