Hi, I have written an app for my raspberry 3 that manipulates strings received from a gps via the GPIO serial port on ttyS0. That works as expected.
Now the problem is when I use a USB to ttl converter and connect the gps to the converter and plug the converter into the usb then my app does not work anymore. I have changed ttyS0 to ttyUSB0 as when I write [quote]cat /dev/ttyUSB0 [/quote] then I can see the gps output strings updating continuously.
