Helium
An mbed wrapper around the helium-client to communicate with the Helium Atom
Helium for ARM mbed
This code repository exposes an mbed library for the Helium Atom module. The Helium Atom makes it easy to securely connect IoT devices and applications to back-end IoT services.
Getting Started
See a getting started guide on the Helium site.
Supported Boards
The Helium mbed client should work with any mbed board with an available serial port.
Example Setup
Example applications can be found in the mbed Helium team.
