I finally got GPS to work on a 3B+. now I have a few questions
You have to shut down the console to use the serial port for GPS. does this prevent logging in via SSH?
does assigning the serial port to GPS prevent the use of the Arduino IDE?
ls /dev/serial* returns /dev/serial0 and /dev/serial1. GPS is on serial0. cgps and gpsmon both show GPS data. cat /dev/serialo returns "device is busy". of course the device is busy, that is the point of entering cat /dev/serialo.
I tried a couple of simple GPS Python programs. one gets data from serial0, the other gets data from gpsd(get). both bail and fail because serial0 is busy. what do you have to do to get this thing to understand that what I need is to see what it is doing while it's busy?
