@Len Sorry for my bad english, but what do you want I send to this email address exactly ?

I did the best I can...

Serial monitor : Arduino IDE: I tried 2 or 3 differents cables. I have the bluetooth dongle but i don't have bluetooth on my computer.

Thank you.

I tried with Arduino Uno, ATMega328P (but this one is clearly 0_1 and not 1_0 like my Nybble), but nothing works... I am not a pro with this hardware and software, but I try... :-)

@Rongzhong Li It doesn't work I guess... Are the LED's colors have a meaning ?

Hello, I've got the same problem: avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0xf8 Windows 10 NyBoard_V1_0 Card : Arduino Uno Port: COM 3 I don't understand anything... (but I don't know a lot of this stuff... :-) )

I thank you a lot. I am just waiting the batteries delivery to continue. :-)

I set correctly the configuration in OpenCat.h (I didn't saw that I had to chose between Bittle or Nybble). The problem with WALKING_DOF is canceled. Thanks.

Yes I can ! :)

@Rongzhong Li Thank you a lot dear Creator ! ;-) No need to read the pin numbers ? It is very convenient but weird... I will check the dos you linked. I will do a feedback here. Have a good day.
