Hi, I have little problem with data transfer to NR from RPI. Have installed nodejs serialport and open serial port. I tryed read data use USB and this work perfectly. I want transfer data from Modbus with RPI. I use UART connect and NR don't accept to read and write, data debug give this error. Serial port send data to AMA0 and BT was deactivated.
Here is log and port setting on RPI.
