    Hi Xavier,

    yes, this is normal behaviour of the Arduino USB interface. This feature (reset based on DTR) is used during the programming. DTR is toggled by the system when the Virtual USB port is open/closed and it is very hard to avoid that.

    But there exists kind of a hack how to prevent this behaviour. Interconnect 5V a and RESET signals at pinheader X1. (But then you must not use the reset button!)

    Please take it really as an unofficial hack. It is not a solution for some product, or industrial application.

    Best regards,

    Lukas
