waste truck weight measurement and GPS system serial interfaces using a USB converter acting as a middle layer. The application will read data

from the a weighing device in binary form, convert it to decimal and sync it with the server database, along with the GPS coordinates fetched from tablet hardware.

• Handshaking and Status of connection update between tablet and device every minute.

• An indicator will be displayed on the top bar showing the status of the connection.

• Pulling data from the serial ports in binary form and converting it to decimal system.

• GPS location data from the tablet will also be sent to server along with the data fetched

• from the device serial port.

• Saving the data on the internal memory of the application of the device so that it is

• preserved until successfully saved on the server database.

• connectivity failure. E.g. Server failure, Internet Failure or Web service failure.
