NexJ's mobile health solution requires its smartphone health coach application to have the ability to read medical measurement data from Bluetooth-capable devices, The devices included in the initial project proposal are as follows: blood pressure device, glucose level measuring device and a weight measuring device.

The health coach application will be designed to use PhoneGap, a rising technology that blurs the line between mobile operating systems. Implementing native Bluetooth adapters becomes only part of the solution. The health coach application will interact with a unified API in JavaScript to retrieve data from Bluetooth-capable medical peripherals.

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.

Project Scope

  • Not responsible for communication with the server.
  • Responsible for communication with Bluetooth peripherals.

Branching Rules

  • Nobody commits to default.
    • default is the master branch we will use to generate submissions back to NexJ
  • Nobody commits to dev.
    • dev is the branch were the latest completed features and bug fixes come together for testing
  • Keep branches relevant.
    • If the focus of what your coding changes, make a new branch
  • Best practice is to branch off of dev.
    • Exceptional scenarios call for branching off of default or other branches, you will not encounter them
  • Branch names in lowercase.
  • Hyphenate branch names if required.
    • bluetooth-plugin
  • Branch names must either be:
    • A bitbucket issue, example: issue-14 OR bug-14
    • A feature name, example: cryptography-bug
