Operation
Quick Instructions
Following are quick instructions for installing and using the Mobile App. For detailed instructions, including
screenshots, see “Detailed Instructions with Sample Screen Shots” starting on page 290.
How to Obtain and Install
Lantronix Mobile App was designed to allow users to take advantage of the convenience features of Near Field
Communications (NFC) and Bluetooth Low Energy (BLE) that are provided in the LSS-2200-8P.
The Mobile App can be used on a mobile phone or tablet equipped with an Android-based Operating System,
NFC reader, and BLE capability.
To access the Mobile App:
1. Using the web browser on your mobile phone or tablet, go to the Download Request page (Log In required).
2. Fill out the form to get the link for download.
3. Read the End User License Agreement; check the box that you have read and agree to the terms and hit
Submit.
4. A Lantronix representative will confirm that you are authorized to access the Mobile App and send you a link
to download. This could take up to 24 hours.
5. Download and save the Mobile App (e.g., eos-mobileapp_1.0.0.0R3) to a location on your mobile device.
6. When you select the Mobile App it will ask you if you want to install it. Select INSTALL. The message
“Installing…” displays momentarily. When the install is complete the message “App installed.” displays.
7. After the install, a prompt displays the options “DONE” and “OPEN“. Click OPEN.
8. To open the Mobile App, select the Mobile App button with the Lantronix logo. The Home page displays:

Lantronix LSS2200-8P MobileApp User Guide
33870 Rev. A https://www.lantronix.com/ 6
9. From the home page there are two options:
INITIALIZE is used with NFC to pre-configure the switch prior to installation.
TROUBLESHOOT is used with BLE to access the switch to check or change configuration or reboot the
switch after installation without having to physically access the switch with a cable.
The options are described in the sections below.
The ideal use case is for the switch to be pre-configured through NFC (the Mobile App) prior to installation or
bootup. The switch is then installed in an out-of-reach location (i.e., high on a pole/wall). The switch is powered up
and the configuration is set in the switch. At this point, the NFC is no longer used for configuration changes (i.e.,
no one should have to climb the pole to get close enough to make changes - and no unauthorized person should
be able to make changes either) All future changes can be made remotely through the GUI or at the site (from the
ground) through BLE using the Mobile App.

Lantronix LSS2200-8P MobileApp User Guide
33870 Rev. A https://www.lantronix.com/ 7
Configure – To create a configuration file follow these steps:
1. Select Initialize.
2. Select the Configure tab.
3. At the DHCP checkbox, check DHCP for automatic IP address assignment, or leave unchecked to
manually enter IP addresses.
4. Set IP Address: you can select Individual to configure a single switch or Range to configure multiple
switches using multiple IP addresses.
5. Enter a Sub-net mask and a Gateway IP address for the switch(es) (required).
6. BLE Enabled (BLE is enabled by default. Unchecking it will disable access to the switch from the Mobile
App via BLE after the configuration is installed. This cannot be reversed from the Mobile App and can
only be done through the web GUI).
7. The Set User Credentials fields are optional:
a. Enter a Username
b. Enter a Password
8. In the Set User Information fields:
a. Enter System Location
b. Enter System Name
c. Enter System Contact person
9. The File Name Prefix will default to config_. You may change it if desired.
10. Press Create File button.
Transfer – is used to transmit the Configuration information into the switch. Note: The switch does not need to
be powered or connected to do this. Follow these steps:
1. Lift the lid of the packaging box that the switch shipped in.
2. On the Mobile App, select INITIALIZE.
3. Select Transfer. The available configuration files display in the box in the left side box on the screen.
4. Select the Mobile App file (the name of the file will be highlighted when selected and the config details are
displayed in the right side box on the screen).
5. Press the TAP AND GO button.
6. Hold the smart phone or tablet so the NFC reader is directly over the NFC target on the front cover of the
switch (the device must be within about 4 cm of the switch).
7. You will hear a “chime” and see a message “Config transferred successfully” when the configuration has
been transferred. If you hear a low tone and see a message “Failed to write, please reposition your
device and try again”, the configuration has not been transferred. Re-select TAP AND GO button and re-
position the device, being sure to align the NFC reader area of the device directly over the NFC target on
the switch cover.
8. The Export button allows you to export the config file to make edits or changes using a different device.
(Note: this is a future enhancement and there is currently no capability to export or re-import files.)
9. You may delete a file after the config file has been successfully transferred or is no longer needed.
Ensure the file name is highlighted and press Delete File.

Lantronix LSS2200-8P MobileApp User Guide

Read NFC Tag – is used to check the configuration of a switch.
1. On the Mobile App, select Initialize.
2. Select Read NFC Tag.
3. Hold the smart phone or tablet so the NFC reader is directly over the NFC target on the front cover of the
switch. Note: the device must be within about 4 cm (1.57 inches) of the switch.
4. You will hear a “chime” when the configuration has been read. The configuration information displays on
the Mobile App screen.
5. If you hear a low tone, the configuration was not recognized. Re-position the device and try again.
The configuration information displays on the screen when recognized. If the switch has been powered
on and the configuration has already been fully transferred into the switch, you will see a message
indicating no config info was detected/the tag was detected but no data exists. The NFC is intended for
use prior to powering up the switch. After installation and power-up, changes should be made via the web
UI.
Troubleshoot – This feature lets you connect with and troubleshoot the switch via the BLE interface.
If you have multiple LSS2200-8P switches in the vicinity you may need the specific BLE MAC Address from the
switch in order to pair the Mobile App with the correct switch. This can be found via the user interface at the
Switch > Security > Management > BLE menu path. Note: use the Mobile App for Bluetooth pairing; do not use
the Android Bluetooth pairing function. Also, The Mobile App will not allow you to disable BLE when the device is
paired.
1. On the Mobile App, select Troubleshoot.
2. Pairing - The Mobile App should automatically start searching for eligible BLE-enabled devices to pair
with. If it does not, select the Retry Scan button to initiate the search. You can limit the displayed devices
to only LSS2200-8P switches by checking the LSS2200-8P box above the Pairing box (checked by
default). If left unchecked, all available BLE devices in the area will be displayed.
3. A list of available BLE devices displays under Pairing in the upper left corner. Locate the one with the
BLE MAC Address for the switch you are trying to troubleshoot. Once the devices have successfully
paired, the BLE MAC Address of the switch will be highlighted.
4. Enter the Username that you selected when configuring the switch.
5. Enter the Password that you selected when configuring the switch.
6. Switch Commands - you can perform several simple actions with the touch of a button:
a. Set IP Address
b. Reboot Device
c. Turn PoE Power On/Off for a specific port
7. Alternatively, you can type CLI Commands in the large box at the bottom of the screen.
Note: If the box indicates “Please do the pairing”, the BLE pairing step must be done before you can
enter any CLI commands (proceed from step 2 above).
For detailed instructions, including sample screen shots, see ‘Detailed Instructions’ below.

BLE Interface
The BLE interface allows access to read/change equipment settings without requiring physical access to the
switch using a console cable once it is mounted high on a wall or pole. The BLE interface provides alarm/status
info, since LEDs and alarms aren’t useful when products are located inside cabinets or enclosures, which eases
troubleshooting effort and cost.
The BLE feature complies with BLE 4.2. If you do not want the switch to be accessible via BLE, the BLE feature
can be disabled using the GUI or in an NFC configuration via the Mobile App. Note: if BLE is disabled via the
Mobile App, it can only be re-enabled via the switch GUI or via the CLI.
Although the Mobile App can be installed on multiple devices, the switch will only pair with one device at a time.
You must re-pair when switching devices/users. Note that anti-virus and password protection are recommended
with BLE operation.
BLE Configuration
Troubleshoot is used to connect with and troubleshoot the switch via the BLE interface. BLE must be enabled on
the switch and the Mobile App paired with the switch. Note: use the Mobile App for Bluetooth pairing; do not use
the Android Bluetooth pairing function.
To use Bluetooth features in an app, you must allow Location permission in your device’s Settings menu.
BLE pairing must be disconnected before trying to disable BLE. If you try to disable BLE while a device is paired,
BLE will not be disabled. The BLE Pairing page is shown below.
Parameter descriptions:
