DESIGNING AND TESTING OF BLUETOOTH LOW ENERGY (BLE) SYSTEM FOR SMALL WOODEN BOAT IDENTIFICATION AND E-CERTIFICATION

Designing and testing of Bluetooth Low Energy (BLE) system for small wooden boat identification and e-certification

Abstract This paper presented the implementation of Bluetooth low energy (BLE) devices implanted on 7 small wooden boats.The BLE implantation is aimed at boat identification and certification.We use four parameters to measure the performance of BLE signal strength, e.g., solar panel usage (with/without solar panel usage), weather effect (sunny/rain
