DrAzzy:
You probably have to disconnect the bluetooth module from pins 0 and 1 in order to upload via the USB port.Nobody is going to download a .zip'ed manual for you... Maybe you should be studying that manual, not us?
That error is extremely generic; it can be caused by basically any problem other than missing drivers or a bad USB cable. Including the wrong board selected, or the whole board having been chopped in half and the piece iwth the microcontroller on it thrown away.
I apologize for the link. I tried uploading the file itself but it said it was too large.
The manual is incredibly simplistic, incomplete and not accurate in many areas. Heavy conversion English interpretations.
I'm not sure how I can illustrate the problem clearly in this forum format. I'm really not trying to be difficult or lazy...just now sure how to convey the problem.
thanks anyway.
