GETTING STARTED
Connect the Firmware
3. Open a Serial Terminal. If you are using Windows, we still
recommend Tera Term serial terminal but there are plenty
of alternatives. Please see our Serial Terminal Basics tutorial
for more details. Open the connection to the CH340 using
115200 baud.
4. Use the Menus to modify the Settings. When you
have the Serial Terminal open, you should see diagnostic
messages from the firmware scrolling up the screen. Hit any
key on your computer keyboard to open the menu.
The firmware settings are stored in flash (non-volatile)
memory when you exit the menus. After changing them,
exit the menus completely, then you can disconnect the
computer and power the GNSS using the supplied wall
charger.
