Bluetooth Low Energy or Bluetooth Ble is the hottest new low-power, 2.4GHz spectrum wireless protocol. In particular, it’s the only wireless protocol that you can use with iOS without needing special certification, and it’s supported by all modern smartphones. This makes it excellent for use in portable projects that will make use of an iOS or Android phone or tablet. It also is supported in Mac OS X and Windows 8+.

To make it easy to use for portable projects, we added a connector for any of our 3.7V Lithium polymer batteries and built-in battery charging. You don’t need a battery because it will run just fine straight from the micro USB connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The Feather will automatically switch over to USB power when it’s available. We also tied the battery thru a divider to an analog pin, so you can measure and monitor the battery voltage to detect when you need a recharge.

The Power of Bluefruit LE

The Bluefruit LE module is an nRF52840 chipset from Nordic, which can be used as both a main microcontroller and a bluetooth low energy interface. For most people, they’ll be very happy to use the standard Nordic UART RX/TX connection profile – code is provided! In this profile, the Bluefruit acts as a data pipe, that can ‘transparently’ transmit back and forth from your iOS or Android device. You can use our iOS App or Android App, or write your own to communicate with the UART service.

The board is capable of much more than just sending strings over the air! Thanks to an Arduino wrapper library, you have full control over how the device behaves, including the ability to define and manipulate your own GATT Services and Characteristics or change the way that the device advertises itself for other Bluetooth Low Energy devices to see.
