Hello,
The easiest way is to use the GPS component to translate the NMEA GPS messages that arrive on the UART receive pin.
There is an example here that demonstrates how to receive and display values on the LCD.

Let me know how you get on.

Hi faran039,
What version of Flowcode are you running?
If you have internet connection you can then load Flowcode and select 'Help', 'Check for updates....'
File opens with V6.0.7.
Do you see any warning or error messages?

Hello,
Can you confirm that the GPS module is sending out data. You can use a program like RealTerm to view the data coming from the module.
If this work ok then ensure you set the COM port and baud rate correctly in Flowcode. You should be able to use the console window to view the raw data coming through on the COM port as well as any GPS data that is being decoded.
