@chefrocker I need this one too.

+1, LUA is fun on microcontrollers!

At least a clap detection function would be very fine for me. I mean none/low/high mic signal or something like that. Thanks!

Jost got the same problem. After fighting hours without any success playing with upload baud rate, frequency and all parameters under the sky, realized that the factory short USB C type cable provided with the Core2 device just works :D

Give that a try.
