One Bluetooth Gateway for Thirty Sensors on a Truck or Trailer

A GO device with the IOX-BT module can hear Bluetooth beacons directly, and for a handful of tags that is enough. A monitored trailer is different: several temperature pucks, one per compartment, door sensors on each door, sometimes humidity or shock sensors, each broadcasting on its own schedule, and the truck's own cab sensors on top. The Bluetooth Low Energy gateway sits between them and the GO device, pairs with up to thirty sensors, collects their readings, and delivers them to the GO device over the IOX port as a single managed feed. The GO device does one job; the gateway does the radio management.

Temperature pucks and probes, door and hatch sensors, humidity, and other compatible Bluetooth sensors, at ranges that cover a 53-foot trailer. The gateway buffers readings when the truck is out of coverage and releases them when the connection returns, so a cold-chain record has no gaps from a dead zone. In MyGeotab each sensor appears as its own data stream on the vehicle, with the rules and reports that follow: an alert when compartment two drifts above setpoint, a door-open-too-long event at a stop, a temperature log per trip for the customer.

Food and beverage distributors with multi-temperature trailers; pharmaceutical and medical couriers with validated cold chain requirements; any carrier whose customer contract specifies continuous temperature monitoring per compartment. It is also the answer for fleets that have hit the practical limit of tags a single GO device can track reliably.

The gateway pairs with up to thirty sensors, which is more than most trailers need, but the count adds up faster than fleets expect once doors and compartments are both monitored. Typical configurations:

The gateway mounts in the trailer or body and connects to the GO device's IOX port; sensors are paired to it once and placed. High Point GPS installs the gateway with the sensors and configures the MyGeotab rules and reports for cold-chain fleets in Quebec, Ontario and the northeastern US.
