Hi, I have been experimenting with the HC-05 bluetooth, I can send commands from my PC to the Arduino easily. But I am wondering how I can upload code to the Arduino via HC-05? Does anyone know of a good tutorial? I would like to make it into something like the Bluetooth EZ-Link break out broad. Thanks.
It sure is prossible somehow, but you would at least need additional hardware to reset the arduino in the right moment.

Edit: Did you even google your question?
First result when searching for "program arduino bluetooth"

Not directly. You would need to alter the boot loader.

Hum, any suggestion how I go about altering the boot loader?
The easiest solution is an Arduino board with embedded bluetooth, coming with the the right boot loader. Then you can use it like any other Arduino board, with upload and Serial communication by BT instead of USB.
No need to alter bootloader. Serial upload just works regardless of whether it is over a cable or over the air. Programming over Bluetooth is quite easy and couka already gave the solution. I use BT to upload to Pro Minis and it works great. I have an instructable for it, http://www.instructables.com/id/Bluetooth-Serial-Adapter-for-Pro-Mini/
