Hi, I am trying to read data from serial port with no luck. I am using USB/Serial converter with pl2303 and I shorted RX TX pins so I can write data to the serial port from nodered and then read them from Linux console with cat -v < /dev/ttyUSB0, I can also send data from console by echo "aaaa" > /dev/ttyUSB0 and then read them with cat command, but I can NOT read any data in nodered.
I have one Serial Output node which is triggered with Inject node and on push is sending timestamp and I have also one Serial Input node which is connected to the debug node. Both of them have status connected. But there are no data in debug node when I press inject. I can see that timestamp was send by cat /dev/ttyUSB0.
I think that problem has to be in Nodered because serial link is working. Do you have any idea what to do or where are any relevant logs stored which I can use to determine what is going on in nodered?
Raspberry pi 3b+
Dietpi - latest
Nodered is running with root privileges
USB/Serial converter - Prolific pl2303
Thank you for any suggestions
