2.2  Typical Network Setup

2.2.1  Overview

MS48-LR supports flexible network set up for different environment. This section describes the typical network topology can be set in MS48-LR. 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 MS48-LR is set to use the WAN port to connect to an upstream network. When you connect the MS48-LR's WAN port to an upstream router, MS48-LR 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, MS48-LR 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

Users can see whether MS48-LR has EC25 on the label of the gateway to determine whether there is 3G/4G Cellular modem.

If the MS48-LR 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 MS48-LR 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.

2.2.5  Check Internet connection

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

• GREEN Tick   : This interface has Internet connection.
• Yellow  Tick   : This interface has IP address but don't use it for internet connection.
• RED Cross     : This interface doesn't connected or no internet.

2.3 The MS48-LR is registered and connected to built-in ChirpStack

2.3.1 Select your area frequency

First, you need to set the frequency plan in MS48-LR to match the end node we use, so to receive the LoRaWAN packets from the LoRaWAN sensor.

2.3.2 Get the only gateway EUI

Every MS48-LR has a unique gateway id. The ID can be found on LoRaWAN Semtech page:

2.3.3 Register the gateway to built-in ChirpStack

Copy Gateway EUI from the previous step to the following interface:

2.4 Register the End-node to built-in ChirpStack

The gateway is already set up to connect to the built-in ChirpStack network, so we now need to configure the built-in ChirpStack. 

Create a device in ChirpStack with the OTAA keys from LHT65N.

2.4.1 Add Device Profiles

2.4.2 Add End Node Device

Enter Device EUI, Join EUI(APP EUI)and APPKEY of the node Device, and select the Device profile added in the previous step

3. Web Configure Pages

3.1 Home

Shows the system running status:

3.2 LoRa Settings

3.2.1 LoRa --> LoRa

This page shows the LoRa Radio Settings. There is a set of default frequency bands according to LoRaWAN protocol, and users can customize the band* as well.

Different LPS8v2 hardware versions can support different frequency ranges:

• 868: valid frequency: 863Mhz ~ 870Mhz. for bands EU868, RU864, IN865, or KZ865.
• 915: valid frequency: 902Mhz ~ 928Mhz. for bands US915, AU915, AS923 or KR920

After the user choose the frequency plan,  the user can see the actual frequency is used by checking the page LogRead --> LoRa Log

Note *: See this instruction for how to customize the frequency band: How to customized LoRaWAN frequency band - DRAGINO

3.3 LoRaWAN Settings

4. Build-in Server

the default factory version of MS48-LR is installed with the built-in Applicant server: Node-Red, LoRaWAN Server: ChirpStack.

Note:

         Path: Server --> Network Server 

                   Server --> Application Server

Troubleshooting:

         1. 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.

4.1 LoRaWAN Network  Server -- ChirpStack

You can access the gateway's built-in LNS server of ChirpStack via the URL( http://<hostname>:8080 or http://<local-IPV4-address> ) in your browser.

Such as  http://dragino-54ff12:8080  or http://<Local-IPV4-Address>

Login account:

Username :        admin

Password:          admin

4.2 Application Server -- Node-Red

You can access the gateway's built-in AS server of Node-Red via the URL(http://<hostname>:1880 or http://<local-IPV4-address>) in your browser.

Such as http://dragino-54ff12:1880  or http://<Local-IPV4-Address>

Using Node-Red, InfluxDB and Grafana

The MS48-LR supports this combination, the default, Node-red is pre-installed but the InfluxDB and Grafana is not pre-installed.

the users can refer to this link to install them.

Upgrade the node.js

By default, the MS48-LR node.js uses the pre-install version v12 which is due to Debian the ultra-stable via ultra-old.

the users can refer to this link to upgrade them.
