Hello dude,
Good day, I have some problem with Serial In/Out node while sending the message to ttyUSB0 of the raspberry pi 4B board.
The setup of the communication is,
Fluke 289 <=> USB IR cable [FT232 chip] <=> [ttyUSB0] Raspberry Pi 4B
I've tested with Arduino serial monitor, it's working. I think the setup configuration of Serial In/Out node wrong, please have a look the flow code below.
