This project consists of carrying out three main processes associated with an application developed on Android. These processes are: weight reading, communication via internet with a public server and invoice printing.The first weight reading process is carried out with the use of a Mettler Toledo BBA231 industrial scale that has a serial port, where the generic Parani SD1000 Bluetooth adapter is connected. The weight is read by the mobile application after pairing and Bluetooth connection.The second communication process via the Internet with a public server is carried out in two moments, the first when starting the application to obtain customerdata and the second to record the details of the sale. This is achieved from the Android application with the use of various communication libraries.The third invoice printing process is performed using the Epson LX-300 + Printer which has a serial port,where custom designed hardware is connected using the HC-05 Bluetooth module. Printing is done from the mobile application after weight reading, customer data synchronization, pairing and Bluetooth connection. Finally, all the data of the sale made is sent to the client's server to be viewed online.
