Arduino BT Problem uploading Sketches

Hello friends of Arduino,

I just received my first Arduino BT and I am pretty excited to test it, but I have some problems with it. I found some posts here regarding my problem, but none of them really fits (I guess :slight_smile: ) .

The board is working well regarding BT connection. It is found and connected. BT on my computer emulates a com40 port and I set the IDE to this port and to BT. It is nothing connected except Power. OS is XP. Blutooth 2.0 LogiLink USB Stick.

As soon as I try to upload a sketch to the board, the IDE tells me
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51

So I am new to all of this and I use 4.8V Power Accumulator, to keep the Arduino BT mobile (should sit on a vehicle once I get it working), could this cause the problem?

Thanks in advance!
Carsten

Finally I figured it out

upload.verbose=true

in the preferences.txt helped. May be I missed it somwhere in the Getting Startet Texts.

Cheers

Hi,

I'm having a similar problem to the one above (same errors), now that you've solved yours maybe you can help me?

What are you using to upload your sketches? I am just using arduino.exe, can't get any sketch uploaded. It will connect via bluetooth ok and sketches will compile but just no uploading

Hi,

I just use a standard blueotooth USB stick on XP and the arduino-0012 arduino.exe. Everything works fine since I edited the preferences as described above. Where the preferences are located is described here: http://www.arduino.cc/en/Hacking/Preferences
Did you set the right Port and board in the Tools Menu?

In the Bluetooth Manager of my Notebook, I set the Arduino BT Connection to Autoconnect, so everytime I send something from Arduino.exe it connects to the board. Don´t forget to press the reset button on the board before uploading.

In additon maybe this can help: Arduino Tutorial - Learn electronics and microcontrollers using Arduino!

And a lot of this stuff is discussed here: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1187909552

yep I changed the port numbers to 2 because I heard that sometimes numbers over 10 aren't accepted. It's on autoconnect (It connects fine everytime it tries to upload). Yep I've tried resetting, even tried changing baud rates on both sides, even though I think BT only works at 115200. I've even tried to burn the bootloader but it won't burn either.
I'm running vista which I think could be the problem. I'll have to see can I try it on another machine.

I've also previously tried all the links you suggested.

Thanks for your reply and suggestions

Its definetly Vista, as you can read here as one of the first answers:

"Sorry pal, but Arduino and the avr-gcc/avrdude backend are pretty much not Vista-ready. Try XP/2000 which is much more likely to work!"

Heh, I could only get it to work under Vista. Ignore the sync error (which I still get) - for me it does actually upload the sketches.
