I have an Arduino BT V06 that I could connect to my Mandriva 2010 linux laptop: "rfcomm connect" is working, /dev/rfcomm0 virtual serial port is created, "hcitool con" shows the connection and "hcidump" displays my upload attempts. However when I try to upload the BlinkWithoutDelay example I got the following error message (upload.verbose set to true in .arduino/preferences.txt):

I was struggling for several hours to solve the problem.
I am using Arduino-0021 but I have also tried it in 0018 and 0015 without luck. I have also tried with board type BT Atmega 168 and BT Atmega 328. My Arduino Duemilanove works fine with the same computer, Arduino 0021, and settings. I have seen several question with the same topic http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1290646119/1 or http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1247005623. They mention differing error messages and anyway I cannot see how can I press the reset button on the Arduino during the upload when I have to type the PIN in a different window.
What could be the solution to the problem?
What I could imagine is to buy a BlueGiga WT11 chip extension to my Duemilanove and do the upload via USB. But how could I be sure that the connection for the communication will work? Moreover I still would like to use the not-so-cheap Arduino BT board.
Based on Nick T's answer I have tried again but the BT still does not work. I have tried to press the reset button - 3 seconds before, - just before, - at the same time of the upload button hit and - when the first two/three avrdude lines appeared - after the first two programmer is not responding lines appeared.
Altogether 20 times without success.
Even when the arduino environment has not been started and I press the reset button on the board the connection is lost (checked by hcitool con) after 1-4 presses.
Are there any other ways to solve the problem?
Do I have to buy a BlueGiga WT11 and hope that the bluetooth connection will work while the USB connection stays OK?
