I think we can just notedown the location from gprs from beginning ofthe journey to the end
now we need to do some cordinate geomentry..
caliculate the lengths between consegutive locations and find the sum of all lengths.. this will be the distance travelled………
Hyperterminal is one good software to test but it is not a free source … I think it is better to use XCTU which is a free source and a flexible tool…
you just connect your RFID module and PC using RS-232 .( if your PC don’t hav a RS-232 use USB to RS-232 converter) .
now in XCTU select the COM port to which your reader is connected to your PC.
there are a set of standard BAUD RATES like 9600 in XCTU select one first and swipe the card.. if the number on card or a unique Hexadecimal code appears in Rx part of XCTU terminal bingo that is the baudrate of your RFID reader….
only thing left is just write a code for USART read and LCD write…
else continue the trial with other Baud_Rates… I think the Baud_rate would be 9600 as I saw many RFID readers having this baud rate
