KG03 Robust Outdoor IoT Bluetooth Gateway


KG03 Outdoor IoT Bluetooth Gateway comes with IP67 enclosure design, is a Robust and strong IoT gateway. It scan/receive Bluetooth 4.0/4.1/4.2/5.0 packet and upload via 3G/4G cellular/Wi-Fi/Ethernet connectivity without using smartphones or apps.
The KG03 Robust Outdoor Bluetooth gateway collects the data from iBeacon, Eddystone, BLE sensor or other BLE devices, and upload data to the local or remote cloud server by MQTT/HTTPS protocol.

The gateway configurations can be updated locally with a web portal, or configured remotely via API from your server. And it also support update the KKM beacons pareameters remotely.

KG03 IP67 Outdoor BLE Gateway comes with industrial design, designed to work outdoor. The engineering design and hardware design make it work in high temperature and low temperature envinronment, such as desert, etc harsh environment.

KG03 Outdoor IoT Bluetooth Gateway supports Bluetooth 5.0 LE Coded PHY long range. PHY Coded and built-in PA make KG03 woring in range of 1500 meters in open space.

KG03 Bluetooth Beacon Gateway provides offline storage, it prevent data packet lost due to the network disconnection.

KKM KG03 IoT Industrial BLE gateway also provide convenient operation & maintanence tools. The user is easy to configure the KG03 Bluetooth gateway | Beacon Gateway via a web/phone UI,  and it support remote configuration.
