Hi,
Thanks for the reply. The first link does not seem to relate to my problem. I can upload successfully via the USB cable and able to control my rebot with a keyboard inputs through the HC-05 module.
But when i tried to upload my sketch wirelessly i got the issue. I have check the troubleshooting steps provided in the second link and seems all what i have connected in my UNO is correct. Is this related to the auto-reset of the UNO? i have tried several reset after i pressed the upload button it still appear the avrdued: stk500_getsync() issue.
Thanks,
Nimpu
