Reading from serial communication not stop and the end of receiving (looping)
Im using Omega 2 with arduino dock 2 and try to test following steps as per documentation: https://docs.onion.io/omega2-docs/uart1.html
I trying to aim following result as per above documentation with following steps:
Now open two separate command line sessions on your Omega. It’s easiest to connect via SSH in two separate terminals from your computer:
- In one terminal, run cat /dev/ttyS1 to start reading the serial port.
- In the other, run echo "hello world!" > /dev/ttyS1 to write a message to the serial port.
As soon as i send this command : echo "hello world!" > /dev/ttyS1 second terminal start to receive and going in loop. How to stop receiving automatically, i know that Crtl+C stop it, but documentation said that it should receive only message but mine going in loop and next value is empty.
Can anybody can advise me?
What do you mean "going in loop"?
Do you have TX1 and RX1 looped together (You should, according to the page)
