- Search for a tty device
Look for a tty device: ttyUSB0 or ttyUSB1 or any other ttyUSBx, which depends on how many USB serial devices you have set up. (This was done on Fedora, other OS's may have a different designation)
- You may need to use sudo to allow permissions to the tty.
- This command will set the device to allow you to log data via tail or cat
stty -F /dev/ttyUSB0 cs8 4800 ignbrk -brkint -icrnl -imaxbel -opost -onlcr -isig -icanon -iexten -echo -echoe -echok -echoctl -echoke noflsh -ixon -crtscts
- View raw data after stty command
- Log Data - You will need to manage the log file sizes
cat /dev/ttyUSB0 >> gps_log
- Log Data with Filter - This significantly cuts down on the number of strings and is really the only string you need.
cat /dev/ttyUSB0 | grep GPRMC >> gps_logs
