- I power-up the Arduino BT-V06, 3V3 Led was ON

- The Bluetooth Dongle deteted it successfully (ARDUIONT) & shows the communication link

- The ST Virtual Serial Port COM3 appearing in the Device Manager Hardware

- I set ST Virtual Serial Port COM3 to 115200\_8N1

- I use the Arduino 0014 Editor, set Board: Arduino BT, set Serial Port: COM3

- Copy Sketch: ASCII Table to Sketch: BT\_V06\_ASCII\_Table, change to Serial.begin(115200); then Save!

- Verify/Compile it with no error

- Hit RESET button of the Arduino BT-V06

- Upload to Arduino board, after awhile, the Arduino 0014 Editor showed:

avrdude: stk500\_getsync(): not in sync: resp=0x00

avrdude: stk500\_disable(): protocol error, expect=0x14, resp=0x51

\*) I tried several times in-vain, anyone knows why I could not upload? ☹

As a forum reply mentioning: after I modifying the preferences.txt (upload.verbose=true) then RESTART system once, it now can be upload successfully! 😃
