When insert the power , The green and yellow Led are lighting, the Yellow LED is go out and the green LED is

blink, the green led is lighting, the gateway boot up successfully.

5.1.2 Reset

Keep pressing the button for 5s. All matching information is eliminated.

5.1.3 Indicator LED

  • Green LED: it is used to indicate system startup

  • Yellow LED: it is used to indicate the operating the Zigbee and z-wave. When the gateway communicate with sensor, the led will be blink. If let the gateway go into pairing mode, the led will be blink.

  • Red LED: it is used to indicate gateway connect with cloud, if the gateway connect with successfully, the Red LED is go out, failed is lighting.

5.2 Wi-Fi Configuration

The Wi-Fi support the AP mode and client mode. It can be switched.

The name of AP : xxxxxxx

Pass word : xxxxxxx

Application List

6.1 AP-01 Monitor Shopping and Street Activity

The smart gateway can be used to detect iPhone and Android devices, which can be detected without the need of being connected to an specific Access Point, enabling the detection of any smartphone, laptop or handsfree device which comes into the coverage area of this smart gateway and in general any device which works with Wi-Fi or Bluetooth interfaces. Users have to do nothing to be detected as the WIFI and Bluetooth radios integrated in their smartphones.

6.2 AP-02 Beacons for Indoor guidance and location

Exemplary deployment of a beacon infrastructure

The beacon attached to the asset to be tracked sends BLE signals to Smart Gateway that are installed in the building. The Gateway processes the provided data and sends it via Wi-Fi, Ethernet to Server. Here, the position is displayed on a map and motion statistics can be retrieved.

6.3 AP-03 Smart Home IOT

The Smart Gateway Working Scenario

The Smart Gateway as the brain of the smart home connects wirelessly with a wide range of smart devices and make them work together.

​

  • Control lights, electronics, and small appliances from anywhere.

  • Set devices to turn on and off at different times of day.

  • Receive alerts when there’s unexpected activity in your home.

  • Set connected lights to turn on and off as people come and go.

  • Monitor moisture and temperature.
