Hi, same issue here. Not able to communicate with the badge. FTDI adapter is ok, shorting RX/TX and echoing chars, Ok, it is able to program a Watterott vCard (it uses the same 328p and no external oscillator). However the badge keeps giving out that error.
I also did a try with bootloader reprogramming. The error is the quite common "device signature = 0x000000", the RGB red flashes green once, then everything is dead. Something happened, because the badge is no more programmed with the blinking of the Faire workshop participant, only the PWR red led is turned on when the board is powered through battery.
any help would be appreciated.. :)
