I have created a tutorial on how to make and use a HC-05 programmer for people who are using these units and want to configure them easily. The tutorial can be viewed here.
I have added a list of Arduino boards and their bootloader baud rates in the Arduino section to assist people with the HC-05 modification allowing you to set the bluetooth module to the correct baud rate.
Have you ever wanted to program an Arduino board over bluetooth instead of having to plug in a cable? It’s possible to do this by modifying the HC-05 board, to see how to do this go to the HC-05 modification page under the Arduino subsection. This modification is particularly useful for agile development or when you have a device in a hard to access area.
