LPS8-V2 supports flexible network set up for different environment. This section describes the typical network topology can be set in LPS8-V2. The typical network set up includes:

• WAN Port Internet Mode

• WiFi Client Mode

• Cellular Mode

2.2.2  Use WAN port to access Internet

By default, the LPS8-V2 is set to use the WAN port to connect to an upstream network. When you connect the LPS8-V2's WAN port to an upstream router, LPS8-V2 will get an IP address from the router and have Internet access via the upstream router. The network status can be checked in the home page:

2.2.3  Access the Internet as a WiFi Client

In the WiFi Client Mode, LPS8-V2 acts as a WiFi client and gets DHCP from an upstream router via WiFi.

The settings for WiFi Client is under page Network -->  Wi-Fi

In the WiFi Survey Choose the WiFi AP, and input the Passphrase then click Save & Apply to connect.

2.2.4  Use built-in 4G modem for internet access

Since Hardware version HP0C 1.4

Users can see whether LPS8v2 has EC25 on the label of the gateway to determine whether there is 3G/4G Cellular modem.

If the LPS8-V2 has 3G/4G Cellular modem, user can use it as main internet connection or back up.

First, install the Micro SIM card as below direction

Second, Power off/ ON LPS8-V2 to let it detect the SIM card.

The set up page is Network --> Cellular

While use the cellular as Backup WAN, device will use Cellular for internet connection while WAN port or WiFi is not valid and switch back to WAN port or WiFi after they recover.

Note: In most cases, the user simply types in the APN and checks the enable checkbox, without typing Pincode, Username, or Password settings.

2.2.5  Check Internet connection

In the home page, we can check the Internet connection.

• GREEN Tick ​​​​   : This interface has Internet connection.

4. Build-in Server

After the v1.7-230606 version, the LPS8-V2 default factory pre-installed the LoRaWAN Server: ChirpStack-V4, Application Server: Node-Red.

1). LoRaWAN Network Server: ChirpStack-V4

Note:  The user can access the ChirpStack-V4 via click the 'Launch' button, and the login account: admin/admin

For more information on server operations see Register LPSV2 to the built-in Chirpstack

2). Application Network Server: Node-Red

Note:  The user can access the Node-RED via click the 'Launch' button

3). Troubleshooting:

•  If the URL does not jump properly.

                For the ChirpStack, you can use the local IP address and the port is 8080 to access it.

                For the Node-Red, you can use the local IP address and the port is 1880 to access it.

•  How to install InfluxDB, Garfana.

                The LPS8V2 is not pre-installed with InfluxDB and Garfana, the users can install them, see InfluxDB 

•  How to upgrade the gateway node.js to the latest version.

                The user can upgrade nodejs, see Upgrade Nodejs

•  How to batch register device on the built-in Chirpstack network server

                The user can register devices in batch on the gateway Web UI, see Batch Register

•  Why my gateway is not Chirpstack?

                After June '23, the default factory LPS8V2 pre-installed Chirpstack-V4 instead of The Things Stack, the users can migrate to Chistack-V4, see Change TTN Stack v3 to ChirpStack

•  How to disable the built-in server

•  How to choose the Chirpstack server frequency SubBand

                The user has to choose a SubBand if using CN470, US915, AU915, or AS923.

                 Note: Since the subbands of the Chirpstack are counted from 0, us915_1 of the Chirpstack is equal to US915 FSB2, so if your LoRa Rdio is using the US915 FSB2 you have to choose the us915_1 as the Chirpstack FSB.

When the configuration is complete, click "Save&Apply".

Note: When adding the device profile, the selected Region configuration is also calculated from 0, so setting it to us915_1 corresponds to US915 Sub Band 2.

11.6 DIN Mount Reference:

12. Trouble Shooting

12.1  I can't log in to the built-in Server TTN Stack which shows 'Login failed'.

This is caused by the inconsistency between the built-in TTN-Stack domain configuration and your login URL.

By default, ttn-stack uses the gateway's domain name for URL resolution, but in some networks, they prefer to resolve IP-v4 addresses.

So you can change the domain name of the TTN-Stack configuration to the IPv4 address.

Click the update URL button to configure the URL with the current eth port address.

12.2  The built-in TTN status is "Not Running" and the URI is "dragino-123456". How users fix this problem

When this problem occurs, click "Update To DEFAULT" ,this problem will be fixed.

12.3  Fallback IP does not work, how can users check

When the computer has completed the above fallback IP configuration,the LPS8v2 Web UI is still not accessible via fallback IP.

1. Check whether the configuration is correct

Run the CMD command to ipconfig and ping 172.31.255.254.

If this fails, the user needs to reconfigure.

2. Check whether the firewall is disabled

If the firewall is not down, this will affect access to the gateway.

12.4  Click "Manual_Update", why there is no response?

When you click "Manual_Update", the gateway will finish updating within 10 minutes and display the update log.

12.5  Why the LPS8V2's Access Point does not do not appear & Fallback IP unable to access
