Impossible to send data to the board(Beginner!)

[Hermios]

Hi Everyone,
First of all, I need to precise that I am an absolute beginner with Drones, Although I'm an ingenieur and have some knowledge with boards and with software.
I got a quadrocoptere for Xmas, to build on my own.
The board is a Nanowii v1.0
I tried to connect it in a first place to my computer, one red led switched on, and the green led blinked. I installed the soft Arduino and sent data (randomly!) to the board, it worked.

After that, I soldered required pins on the board, connected to the receiver (for the fun) and reconnected to my PC. There is no batterie right now. Now, the red light is still on, but the green light switch on, then switch off after two or three seconds. My PC consider then that the board is disconnected.
I tried to reset the board (I established a connection between the pin RST and the ground), it restarts the board, the green light blinks again, but the result is always the same, at the end, the green light is off and the board is considered as disconnected from the PC.
I know it looks bad, but I hope it is just a look! Can you tell me how I can fix it?
Please feel free to tell me if you need more information.
Thanks a lot

Niko

Re-check that you soldered to the correct pins and that there is no solder shorts.

Hi Waltr
Thanks a lot for your answer.
You were right, I soldered a shortcut.
I just fixed it, and now, The green light blinks again.
BUT (Sorry!), I still can't send any info from Aduino to the board. I reseted, no change.
The error :
avrdude: stk500_getsync(): not in sync: resp=0x00

Any idea?

Thanks

Niko

That is a very Common Arduino error.
Re-check that you have the correct board type and programmer selected in the Arduino IDE.
Info on this should be in the nanowii document.

It works! Many many thanks

i have the same error in crius multiwii SE 2.5.
When i send data the blue led start blinking whit the same patron and nothing works
I tried varioustype of programer an nothing and i tried to reinstall the ftdi driver too....

i wish someone can help me... an sorry for my bad english

Hi Diego
As Waltr said, did you check your soldered connection? I got a shortcut, it made things working strangely. Otherwise,for uploading a program to the Board, I make a quick reset between the compilation and the update. This is a constraint, but it seems that is due to a bug in the Arduino's Software.
I hope I helped.
