I am trying to connect Arduino UNO in my project through UART. When I am using hardware Serial port(Pin 0 and Pin 1 of arduino UNO) of Arduino UNO, I am only able to receive data sent by Arduino on Jetson NANO. While, when I am sending data to Arduino from Jetson NANO I am unable to do it, there is nothing visible.
On the other hand, when I am using software serial (Using Pin 9 and Pin 10 of Arduino) of Arduino UNO, I am able to send as well as receive data from both ends (Jetson NANO as well as Arduino UNO).
I am also facing the same issue with FTDI cable as well. I don’t have an oscilloscope with me so I can’t check whether NANO is unable to send data or there is some other issue. In addition to this, PL2302 works great in my project.
I am using minicom on NANO to send and recieve data.
