Is it possible to upload sketches over Bluetooth to an Arduino?

Hi again. ^___^
I have a feeling that the bluetooth module is broken because after following pretty much every tutorial out there, I can't seem to get a piece of software to detect it so I've given up on that for the time being. :frowning:

Just another question - how would I go about programming the ATmega328 using a wired connection? Could I simply just connect the RX and TX from a serial port in reverse to the RX and TX on the ATmega328 (i.e. RX/TX and TX/RX)? Or is there something more detailed that requires to be done?

Thanks again in advance! XD
