Nano Pi Neo Plus 2 (/dev/ttyS1) Serial transmission issue
Posted: Sat Jan 20, 2018 4:02 am
Hi,
I'm using an Arduino to communicate with NanoPI Neo Plus 2 using command. While sending the data, I receive random characters -
Arduino Code -
This happens even with pySerial or any other Serial communication. I am not able to communicate with any UART device since the data is garbled before it reaches the other device.
This works with a USB UART but doesnt work with Serial pins.
