[[File:NexjPhoneGap.png|right]]== Bluetooth Details ==
=== Bluetooth Profile ===
mobile devices, including iOS and Android smartphones/tablets.
== Process Description of Bluetooth Communication == [[File:NexjPhoneGap.png|right]] === Communication Process Description for unpaired devices in brief: ===
* Enable Bluetooth on the mobile device and set the device to discoverable mode (as slave device).
* Upon the success of connection, the two devices are paired. Then PIN code is no longer needed afterward.
=== Communication Process Description for paired devices in brief: ===
* Enable Bluetooth on the mobile device and set the device to discoverable mode.
* Make a measurement on selected A&D Bluetooth device. Upon the completion of measurement, the A&D Bluetooth device checks its memory for previously paired address of mobile device and directly sends the measurement data to the mobile device using the specified format, followed by the Confirmation Packet Response.
=== Communication Packet ===
Communication packet consists of two sections: the dataheader section and the data section.
