ABSTRACT
This chapter provides a brief guide to connecting an Android smartphone with an external Bluetooth-enabled sensor. Bluetooth is a wireless technology to exchange data over short distances interconnecting fixed and mobile devices in Personal Area Networks (PANs). The standard is managed by the Bluetooth Special Interest Group, which consists of more than 17,000 companies in the information technology field. Bluetooth broadcasts in the 2.4GHz Industrial, Scientific, and Medical (ISM) frequency band and is frequently used to connect headsets and printers, perform file/data transfers and, as in this case, connect other external devices, such as sensors.
