Topic: Arduino UNO upload delay (Read 945 times) previous topic - next topic



I've been playing around with arduino Uno board. the only thing that's getting me down is upload times.
when upload button is clicked, the software waits for around 30-40 seconds (during which time nothing happens) and then uploads the sketch in couple of seconds (as shown inside IDE itself and flashing rx/tx leds on arduino board).

Is it possible to decrease(or remove) this initial delay as it's slowing the development down a great deal.

UPD: forgot to add that i'm running Windows7 and using 0022 version of Arduino IDE. there are only 2 com ports listed in tools menu.


Found a possible solution here:


points to Comodo firewall as the culprit for slow complication times.

preliminary results are positive, will do some proper testing later tonight.


done some tests. while COMODO firewall does seem to have an effect, it's rather negligeble on my system.

Still looking for solution.

How long does compiling+uploading for everyone else? (i'm using a 46 line sketch)
