lilypad protosnap not working: avrdude: stk500_recv(): programmer is not respond


I just bought a lilypad Protosnap like this, and when I plug in my lipoBattery eveything works. (lights, buzzer, button)

now I am trying to follow the Quickstart here: LilyPad Development Board Hookup Guide -

My FTDI driver is like this, and I download the FTDI driver here:VCP Drivers - FTDI (version 2.4.2)

Board: lilypad arduino, Processor: ATmega328, Porter: /dev/cu.usbserial-A9AXPZJY (that's the only porter available and another one is Bluetooth)

I tried the basic blink code from example while all the lights are just blinking and the buzzer is beeping just like before. and the there is avrdude: stk500_recv(): programmer is not respond. I dont know what's the problem here? :frowning:

I already fixed the problem. It turns out that the FTDI converter I got is wrong. I bought another one which is produced for Lilypad (and more expensive) specifically and now everything works very well!!

I just provide my solution here in case that some people meet the same problem.
