I fried my arduino. Can I upload code wirelessly?
If the main MCU is still functioning fine then yes, sure you can.

The only caveat is that you may have to manually reset the Arduino at the right moment in order to enter the bootloader for programming.


Connect the bluetooth module to TX/RX/GND (TX->RX, RX->TX)
Configure the bluetooth module to work at the bootloader baud rate (115200 baud) - you may need to wire it to your PC to manage this part.
Connect a virtual COM port to it and program through that.
Press RESET just as it's about to run AVRDUDE in the IDE.
