BLE Driver

[agwoska]

As a developer, I want a BLE driver to communicate with smart devices so data and events can be captured.

Background Information

There already exists a KW40Z driver (link is in hexi_libs.txt) but it does not support the values that we want to send. We are planning on creating a custom app that will use the data sent from the Hexiwear device to capture data and activate events. This being the case, the entire KW40Z driver is being rebuilt to support these upgrades.

Acceptance Criteria

• [x] the KW40Z driver exists
• [x] KW40Z support buttons with events
• [ ] KW40Z supports BLE
  • [x] can be paired and connected to smart devices
  • [x] can send events correctly
  • [ ] can receive events correctly
• [ ] KW40Z works as intended

Driver on Mbed is sufficient for now
