9.6 Calibrated Internal RC OscillatorBy default, the Internal RC Oscillator provides an approximate 8.0MHz clock. Though voltageand temperature dependent, this clock can be very accurately calibrated by the user.

Hi everybody! Well, I'm making a school-proyect that envolves the atmega328P-PU (basically the duemilanove chip as the stand/alone mode with boot-loader). I tested it in a breadboard with a crystal of 16MHz and the capacitors of 22pF communicating with a bluesmirf (bluetooth antenna) at 57600bps to my pc with a bluetooth dongle and also with an android phone and works great!!!!!Now I want to reduce the components to get the smaller I can the proyect. So... if I take out the crystal (obviosly also the capacitors) and use the internal oscillator: Would that make my whole proyect fail because the RS-232 communication needs some accuracy or which troubles i can get??? I have read some stuff but some people say that there would be no problem but others say that by using the RS-232 communication it has to be very accurately.
