One Bluetooth Gateway for Thirty Sensors on a Truck or Trailer

A Bluetooth sensor gateway, or Bluetooth gateway, is a Bluetooth Low Energy device that pairs with up to thirty sensors on a truck or trailer and passes their readings to the GPS tracking device over the IOX port as one managed feed. A GO10, through its built-in Bluetooth, or a GO9 with the IOX-BT module can hear Bluetooth beacons on its own, and for a handful of tags that works. A monitored reefer is a heavier load: a temperature puck per compartment, a sensor on each door, sometimes humidity or shock sensors, each broadcasting on its own schedule, plus the truck's cab sensors. The gateway sits between those sensors and the tracker and takes over the radio management.

Temperature pucks and probes, door and hatch sensors, humidity sensors and other compatible Bluetooth sensors, within the gateway's Bluetooth range. Out of coverage, the gateway buffers readings and sends them when the connection returns, so a dead zone leaves no hole in the cold-chain record. The High Point GPS platform shows each sensor as its own data stream on the vehicle, ready for rules and reports: an alert when compartment two drifts above setpoint, a door-open-too-long event at a stop, a per-trip temperature log for the customer.

Food and beverage distributors with multi-temperature trailers, pharmaceutical and medical couriers with validated cold-chain requirements, and any carrier whose customer contract calls for continuous temperature monitoring per compartment. It also suits fleets that have outgrown the tag limit of one GPS tracking device.

Thirty is more than most trailers need, but the count climbs faster than fleets expect once you monitor doors as well as compartments. Typical setups:

The gateway mounts in the trailer or body and connects to the tracker's IOX port. You pair each sensor once, then place it. High Point GPS installs the gateway with the sensors and sets up High Point GPS platform rules and reports for cold-chain fleets across Canada and the United States.
