Dear All, I am a newbie and it is my first time using Node-Red.
My Node-Red is running on Raspberry Pi 4. For learning purpose I am trying to read ESP32 device connected to RPi via USB. I am able to display the output in terminal using "screen /dev/ttyUSB0 115200". But the problem is, Node-Red can not recognize the serial input, showing:
"serial port /dev/ttyUSB0 error: Error: Error: No such file or directory, cannot open /dev/ttyUSB0".
Basically, it shows "not connected". Is there anything I am missing?
When I run "sudo ls /dev/ttyU*" command, I can see "/dev/ttyUSB0" listed.
