Mike Fiore 1:9f30fbe9e9c1 9 The mDot header has documentation for all the public functions that will be useful to consumers of
Mike Fiore 1:9f30fbe9e9c1 10 the library.
Mike Fiore 1:9f30fbe9e9c1 11
Mike Fiore 1:9f30fbe9e9c1 12 The following source code provides an example application which configures the mDot, connects to a
Mike Fiore 1:9f30fbe9e9c1 13 MultiTech Conduit gateway with matching configuration, and sends data packets to the gateway.
