1. Purpose
This document describes the basic functions and physical interfaces of the KGateway, which
are mainly used to guide users to install and configure.
2. Introduction
The KGateway is made of PC material and is waterproof and dustproof. It supports outdoor
installation and can be installed by wall mounting.
After the KGateway power on, it will periodically scan the KBeacon advertisement packet
then report the data through Wi-Fi or Ethernet. Also it can accept data command from the cloud
and forward the data to KBeacon, such as updating the KBeacon configuration. The KGateway
uses open MQTT + JSON API interface for third-party integration.

3. External interface
3.1 Network interface
The KGateway supports following ways to connect to the internet:
1. through Wi-Fi;
2. through the Ethernet cable;
3. Though Cellular network (optional, only available when the LTE usb dongle was insert);
4. The KGateway supports Wi-Fi Hopping, which means one KGateway can connect to
internet by another KGateway.
3.2 Power supply interface
There are two interfaces for power supply: macro USB interface and Ethernet POE port;
POE power supply, directly through the Ethernet cable interface, using POE(802.3af) to
supply power.
Macro USB power supply, powered by the 5V/1A DC.
Warning: The KGateway can only use one of the two power supplies at the same time.
Please don’t insert two power supplies at the same time, otherwise KGateway may be
damaged.
3.3 LED indicator
The gateway has 2 LED indicators. The specific meanings are as follows:

Copyright by KKM Inc. public 5/ 33
1. Red indicator light:
If the red led flash, it means the gateway connect to the cloud fails.
2. Green indicator light:
2-seconds or less frequency flash: indicates that the KGateway is successfully
connected to the cloud and report KBeacon advertisement packet success.
10-second frequency flash: indicating that the KGateway connect to the cloud success,
but it didn’t find any KBeacon devices.
3.4 Insert LTE USB dongle SIM card (If needed)
Please note: This procedure is only for KGateway with USB dongle and LTE module
installed.
Disassemble the gateway and insert the SIM card at the position indicated in the picture
below.
4. Configuration
The KGateway is configured in web portal mode. You can use an web browser to configure it.
Chrome browser is recommended to use for the configuration.

As shown above, each base station has two interfaces with different IP addresses. One of
these IP addresses (referred to as the WAN port) is used to connect to the internet network
(MQTT server), which has a series of firewall rule protection. The other IP address (referred to
as LAN port, also known as the intranet interface) is used for Wi-Fi hotspot broadcasting.
WAN Port: This interface supports Wi-Fi and ETH (network wire). KGateway can
connect to routers via Wi-Fi or network wire, where IP addresses are assigned by routers. The
base station is connected to the MQTT/HTTPs server through this interface, so you need to
ensure that the network between this interface and the MQTT server is interconnected. WAN
address IP address configuration see "4.3.2 configuration WAN port network connection".
LAN port: This interface only supports Wi-Fi. The default IP address of this interface is
192.168.8.1, PC can connect to this interface through Wi-Fi, or the next hopping KGateway can
connect to the internet by Upper level.
If you need to configure the gateway, you can only configure it through Wi-Fi, and you
cannot configure it through the network line (for security reasons, the network line interface
only supports the WAN interface).
4.1 Connect to KGateway
After power on, the KGateway will automatically broadcast Wi-Fi signal, and the default
Wi-Fi name is “beacongw_mac address”

KKM Co.Ltd KGateway(for KBeacon) Configuration
Copyright by KKM Inc. public 7/ 33
The default Wi-Fi connection password is“12345678”
The default KGateway configuration IP address is 192.168.8.1
Login in to the gateway by typing http://192.168.8.1 in the browser.
5. Enter the user name: ‘admin’and password: ‘admin’
4.2 Network interface
4.2.1 Configure WAN interface
Tap on Network to go to the network configuration page. You can choose to connect to the
internet network using Wi-Fi /Ethernet/Cellular connection.

KKM Co.Ltd KGateway(for KBeacon) Configuration

4.2.1.1 Connect to internet by Ethernet
The IP address can be assigned in DHCP or static configuration.
4.2.1.2 Connect to internet by Wi-Fi

KKM Co.Ltd KGateway(for KBeacon) Configuration
Copyright by KKM Inc. public 9/ 33
Click on “Nearby WLAN”, then you can see the Wi-Fi name and the signal strength (0~100).
100 means the signal is very strong.
Connect to an hidden Wi-Fi AP:
You can see some Wi-Fi name like mac address; it means that Wi-Fi was hidden. You should
input the Wi-Fi name and password if you want to connect to it.
If your Wi-Fi AP name does not appear in the nearby WLAN list, please try to reboot
the KGateway. (In others page, you can reboot the device)

4.3 Service configuration
Click Services to go to the service configuration page, where each field is defined as follows:
4.3.1 Advertisement Upload Parameters
Click Services to go to the service configuration page, where each field is defined as follows:
1. Upload period: KGateway uses this parameter to control upload period of modified
advertisement data about KBeacon to Cloud.
It needs at least Upload period seconds for KGateway to send advertisement to cloud when
KBeacon advertisement data change.
2. Redundant Upload period: KGateway uses this parameter to control upload period of
unchanged advertisement data of KBeacon to cloud. The cloud uses this parameter to keep alive
for all KBeacon.

KKM Co.Ltd KGateway(for KBeacon) Configuration
Copyright by KKM Inc. public 13 / 33
3. Max Packet Size: This parameter is used to control max packet size when upload KBeacon
advertisement data to KBeacon.
4. Rssi filter: If this parameter is set, the KGateway will only report the advertisement packet
which signal is > Min Rssi value.
5. Ble Services filter: If this parameter is set, the KGateway will only report the advertisement
packet which includes the setting BLE services ID.
Following example is using Lightblue app on IOS to view the device service UUIDs, then you
can set the services filter to 0xFEA0.
6. BLE mac filter: KGateway can use this parameter to filter KBeacon mac address. This
parameter uses Regular express.
For example, if Ble Mac filter value set to ^20DD, then following KBeacon advertisement packet
will report to cloud.
KBeacon1: ble mac = 0x20DD01000002 : report to cloud
KBeacon2: ble mac = 0xA133DD010002 : not report to cloud
KBeacon3: ble mac = 0xA10005033DD2 :not report to cloud
7. Raw data filter: KGateway can use this parameter to filter KBeacon advertisement packet.
This parameter uses Regular express.
8. Upload iBeacon: ‘Yes’means KGateway will report iBeacon protocol advertisement.
9. Upload Eddystone: ‘Yes’means KGateway will report Eddystone(URL/TLM/UID) protocol
advertisement.
10. Upload KSensor: ‘Yes’means KGateway will report KKM KSensor protocol

4.3.4 HTTP configuration
1. Service Access: select HTTP and the KGateway will using HTTP protocol to connect to
cloud server.
2. Authentication: The KGateway support single password authentication for HTTP post.
3. Url: The cloud HTTP service.
We provide a test HTTP server and the URL address is:
http://api.ieasygroup.com:8091/postdata

KKM Co.Ltd KGateway(for KBeacon) Configuration
Copyright by KKM Inc. public 19 / 33
Also the KGateway can support simple password that connect to clouds.
4.4 Modifying the Web Portal Login Password
The default login password is “root” and users can change it to other password.
5. Quickly verify KGateway API
In order for customer easily integrates our gateway, KKM provides test servers for HTTP

KKM Co.Ltd KGateway(for KBeacon) Configuration
Copyright by KKM Inc. public 20 / 33
and MQTT.
5.1 How to verify HTTP API
1. The gateway is setting to MQTT server by default after factory. So please reference
section<< 4.3.4 HTTP configuration>> to change the service’s type.
2. KKM provides a test HTTP server, and the address is:
http://api.ieasygroup.com:8091/postdata
3. After KGateway connect to the HTTP service success, it will flash green LED and
periodically post the KBeacon advertisement data to HTTP server.
4. You can view the reported data on HTTP server by follow address. You should replace the
mac address to your KGateway.
http://api.ieasygroup.com:8091/viewdata.jsp?mac=D03304001182
5.2 How to verify MQTT API
Download mqttfx software:
http://www.jensd.de/apps/mqttfx/1.5.0/
Please reference the document << KGateway API Specification.pdf>> for other details.
6. Trouble shooting
6.1.1 The KGateway flash red LED
If the KGateway connect to HTTPs/MQTT server success, it will flash green LED, otherwise
it will flash red LED.
If the KGateway flash red led, please check the connection by following steps:
