I tried everything i read in this forum and other forums.
i can connec to the arduino .
i chose the right board and right port #
i tried to push rest before i hit upload / after i hit upload ! i tried pushing the reset before powering the arduino BT and then release and upload
nothing work ..... please help me and tell me what to do ! 
any help is appreciated !!
Try to press reset when the IDE finishes verification of the code and the length is displayed in grey.
i tried all times. i still get protocol error or cant sync !
this is a poor design , is that the only way to load the code to the arduino without editing the programmer !
It is very hard to upload sketches wirelessly. I tired for a few days over xbee.
The problem is the Arduino needs to reset and start receiving code at a specific time. You can try and time it but I couldn't.
With the Xbee you can use a DIO to do a remote reset, but the bootloader doesn't leave enough time so sparkfun.com has a updated bootloader that allows more time to allow for wireless upload. It might work for BT. It is really unfortunate because for me it would make thinks much easier and I am sure for many others.
