The mc-Dongle allows Over-The-Air programming of mc-Module devices.
It is required for updating the firmware on your mcModules and the mcGateway. These firmware updates provide increased functionality and are used to keep your platform up to date. If you purchase a mc-Modules and mcGateways, be sure you include an mcDongle as this is a required piece of the mcThings platform!
The mcDongle is used with the mcOTA application to provide over-the-air firmware updates to the mcThings devices/modules
