This example establishes a transparent link between the mbed serial port and the gps I2C on the C027. You can use it to use the standard u-blox tools such as u-center. These tools can then connect to the serial port and talk directly to the GPS receiver. Baudrate should be set to 9600 baud and is fixed. m-center can be downloaded from u-blox website following this link: http://www.u-blox.com/en/evaluation-tools-a-software/u-center/u-center.html
