Jetson Xavier Nx SerialPort

I am trying to connect to “/dev/ttyTHS0” communication port from a node js application, but the NX cannot connect to the port. It doesn’t even list the port when I try to list the ports. It has no problem with communicating through USB to serial adaptor or convertor.
There is no problem connecting to “/dev/ttyTHS0” through a Python program. Is there a permission problem with node js or the issue is something else?

may I know what’s the “node js” you mentioned here?

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.

Hi amir.babaei,

Is this still an issue to support? Any result can be shared?
