Setting the update rate of the GPS Mouse - GP-808G

GPS/GNSS Development Boards
1

Using the GPS Mouse - GP-808G with TinyGPS++.h and SoftwareSerial.h

Default update rate is 1Hz.

Unit is can run up to 10hz.

How do I change the update rate?

Hello ETM.

The easiest way to change the update rate on the GP-808G is through the u-center software available [here. You will need to open a “configuration view” window and then go to the “RATE” section to change the update speed. Once you’re done, close the configuration view window and an option to save the new config to the GPS should appear and that will save the new rate in nonvolatile memory on the GPS.](u-center)

Can’t get U-Center to communicate.

Giving power and ground to the GP-808G.

Connecting via serial port. Green and White TX/RX on GPS crossed to serial pins 2/3 RX/TX.

U-Center knows something is there. Com symbol on status bar blinks red and green when GP-808G is powered and goes black when not powered / no data. I’m confident that the serial and baud is set correctly.

The Arduino and sketch running on the Arduino are interfering with U-Center’s ability to communicate with the GPS.

You’re going to need to connect the GPS to your computer with a USB to serial device like an [FTDI Basic Breakout and program it that way.](https://www.sparkfun.com/products/9716)
