---------------------------------------
Getting Started with the mDot Library
---------------------------------------

This README should get you started using the mDot library with your MultiTech mDot.

License information can be found in the accompanying LICENSE file.

The mDot header has documentation for all the public functions that will be useful to consumers of the library.

The following source code provides an example application which configures the mDot, connects to a MultiTech Conduit gateway with matching configuration, and sends data packets to the gateway.
