Hi there.
I have a Winsen sensor ZPHS01B, and have a problem with reading it. Here is my code, everything compile without an error, but after this I receive the error for every byte which I tried to read as follow:
“[20:44:51][E][uart:015]: Reading from UART timed out at byte 19!”

And here is a datasheet for this sensor as well
Is there some one who can help to resolve this?
Thank you in advance
