IoT Concepts

Trimble IoT uses the following concepts

Concept	Details
Access keys	Access Keys are the credentials used for accessing the delivery endpoints.
Application	An application can be a downstream processor that consumes messages from delivery endpoints or sends outbound commands.
Device	A device is an entity that communicates through the IoT gateway. It possesses a serial number, model, manufacturer and a certificate to connect and communicate through the gateway.
Device certificate	A device certificate is an x.509 certificate that is embedded in a device hardware which provides proof of the device’s identity.
Direct method	Direct method refers to a request-response interaction with a device similar to an HTTP call in that they succeed or fail immediately after a response timeout.
Gateway	A gateway refers to a TCP/UDP/MQTT message broker that enables devices and applications to communicate with each other in a secured manner.
Group	A group is a collection of devices that share common traits. A group can be based on “device model” or “device fleet”.
Inbound messages	An inbound message/events (device-to-cloud message) refers to the message routed from a device to a gateway and delivered to an application. For more information, click here.
Message routing	Capture, filter and route events to various delivery endpoints.
OTA update	An over-the-air (OTA) update is a wireless transfer of new software, firmware or other updates to a device.
Outbound messages	An outbound message/events (cloud-to-device message) refers to the message routed from an application to the device. For more information, click here.
