    Hi @sara,

    I am trying to connect a y4000 to my arduino using an mkr 485 sheild (RS485) for hardware serial port  using your arduino library for y4000, till now with no luck.

    I suspect it is because of the “AltSoftSerial” creating software port while I am using a hardware one, but I am not sure how to modify this.

    Can you please help with some tips or thoughts?
