Device control methods
AirNgin supports different control paths depending on the hardware capabilities of your product.
Internet
The standard path is cloud control through the AirNgin MQTT architecture. Direct Devices connect to AirNgin with their provisioned MQTT credentials and use the Direct Device topic contract.
SMS
Products that contain a GSM/SMS capability may also support the AirNgin SMS control flow. SMS is an additional transport for eligible products; it does not replace the normal AirNgin device identity and permission model.
See the SMS & Push Notifications section for the SMS-specific contract.
