DFU Updates
We're constantly working on the Bluefruit LE firmware to add new features, and keep up to date with what customers need and want.
To make sure you stay up to date with those changes, we've included an easy to use over the air updater on all of our nRF51 based Bluefruit LE
modules.

Updating your Bluefruit LE device to the latest firmware is as easy as installing Adafruit's Bluefruit LE Connect
