Utvärdering och design av trådlös kommunikation mellan smart dosett och Smartphone

Sammanfattning: A product with the need for a wireless communication between itself and a smartphone will be developed. A suitable wireless protocol and module will be chosen and evaluated. How should the software be designed? What functions should be available? In the end the module and software will be tested in the field to see how it works in reality. For the choosing of protocol, the following will be discussed; ZigBee, Z-wave, Bluetooth Low Energy, WIFI and the common mobile network. The main point of the discussion will be energy consumption, range, transfer rate and the need for additional hardware in order to work with a smartphone. Bluetooth Low Energy was chosen mainly because the wide use of the product with in the smartphone market. Due to the fact that Bluetooth Low Energy already is integrated in most of the new smartphones no additional hardware was needed in order to make the communication work. Both ZigBee and Z-wave also had a very low power consumption and both WIFI and the mobile network had a great data transfer rate. A flowchart was designed to show the need of functions within the software and the task of the communication between the product and the smartphone. From the flowchart all the functions needed was defined. Unfortunately, the company’s own product was at this time not completed. Without it, not all functions were possible to implement. The module PSoC BLE from Cypress Semiconductors was believed to be able to perform as Finn Medicinen required. The field tests proved that this module, with this implementation, handled several reasonable situations well.
