Hi, I need to split the data flow from the serial port if the character is \>= 0x80.
The problem is that in Serial node config I can input just 0x80. Is there a way to put greater or equals then \>= 0x80, instead of just 0x80?
Thank you in advance!

Not in the serial node no. You would need to read either all then input and then split, or read one character at a time and discard until you saw what you want.
