FAQ

Does the KG04 support ethernet network connectoin?

KG04 series only support WiFi connection.
If you need ethernet, you can use KG01/KG02/KG03/KG06.

Can I use MQTT TLS?

KG04 supports HTTP(S) and MQTT TLS.

Does KG04 USB gateway support data pre-parsing?

KG04 gateway support pre-parsing standard iBeacon, Eddystone UID/TLM/URL and KKM Kensor, System protocols.

Does KG04 USB gateway support remote configuration?

Yes, the KG04 support remote configuration from server via HTTP or MQTT.

Does KG04 support configure BLE tag?

We have KG04 (only support scanning & uploading data to cloud) and KG04S (support scanning & uploading data to cloud and reading and configuring beacon parameters).

Please contact our sales team for more information.

Does KG04 support duplicate data filter?

KG04 USB gateway support filter data by RSSI, Mac address list, Mac RegEx and raw data. 
For duplicated data, KG04 USB gateway support filter by Mac address, Mac address + Type, Mac address + raw.

Does KG04 support WPA2 Enterprise WiFi?

WPA2-Enterprise is a secure authentication method designed for enterprise wireless networks. It uses a RADIUS server to authenticate users before they connect to the access point.

The authentication process follows the 802.1X standard and supports multiple EAP methods, including TLS, TTLS, and PEAP.

Currently KG04 gateway doesn’t support WPA2 Enterprise WiFi. You can use KG05, KG06 which support WPA2 Enterprise WiFi.

We are also happy to listen and make it happen to the KG04 USB gateway.

What does red LED blinking mean?

Red LED flashes rapidly: The device enters the network configuration state
Red LED flashes slowly: The device has successfully connected to Wi-Fi and is trying to connect to the server.
Red LED remains on: Device is connecting to Wi-Fi.
Green LED remains on: The device connects to the cloud server successfully
