The unified JavaScript API will be developed to utilize PhoneGap's JavaScript API to make native code calls. These native calls will focus on a medical Bluetooth device adapter which also must be implemented. This Bluetooth adapter will be extended for each supported measuring device and implemented on each supported mobile operating system.

Measurement date/time, measurement values, Bluetooth Id of remote unit, mode, and serial number of A&D PBT Series.== [[:Category:NexJ_Express_Research|Research]] ==
=== Master devices === A&D Bluetooth® devices PBT series, including blood pressure meter, blood glucose meter, and weight scale. === Slave devices/Access Points === mobile devices, including iOS and Android smartphones/tablets. === Communication Process Description for unpaired devices in brief: === * Enable Bluetooth on the mobile device and set the device to discoverable mode (as slave device).* Make a measurement on selected A&D Bluetooth device such as weight scale. Upon the completion of measurement, the device (as master device) searches slave devices and initials Bluetooth communication.outline: [[Phonegap_Healthcare_Adapter_Bluetooth_Spec|Spec]]* The mobile device receives the signal of the A&D Bluetooth device and prompts user to enter a PIN/passkey.native implementation: [[Phonegap_Healthcare_Adapter_Bluetooth_Implementation|Details]]* Once the PIN is matched, the A&D Bluetooth device sends the measurement data to the mobile device using the specified format such as weight scale packet followed by the Confirmation Packet Response.* 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 briefProject Design: ===[[Phonegap_Healthcare_Adapter_Design|Design Page]]* 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 sectionsPhonegap cross platform plugin solution: the dataheader section and the data section. ==== Header Section ==== {| class="wikitable sortable" border="1" cellpadding="2" width="800px"!
