ArduinoBT Heeeeeeeelp!!!

by ryan on Thu Feb 14, 2008 8:08 am

Hi,

I can't seem to upload anything to my ArduinoBT?
I have checked correct com port, baud rate etc and I keep getting error mesage:

avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51

I haven't much experience with Arduino so I was wondering if its something simple.

Any ideas?

Thanks
Ryan.

two things:

make sure you don't have anything connected to your tx/rx pins, 0 and 1. the atmega can't communicate serially with the BT if there's something else connected.

the other thing is that the BT unit is very temperamental. you need to reset it and upload within 2 seconds, or just keep trying new combinations of reset + upload. it's finicky.
