Product Configuration

Accessing Your Gateway

After burning the firmware image onto the SD card, make sure you have inserted the SD card into the RAK7244 WisGate Developer D4 Gateway and have the LoRa and GPS antenna connected. To learn more on how to burn the image, check the Learn section.

After which, you can now safely power on the gateway. In this section, several ways to access the gateway are provided to have different alternatives for you to choose from depending on the availability of the requirements needed.

warning

Before powering the Raspberry Pi 4, you should connect the LoRa and GPS antennas. Not doing so might damage the boards.

Wi-Fi AP Mode

By default, the gateway will work in Wi-Fi AP mode, which means you can find an SSID named Rakwireless_XXXX on your PC Wi-Fi network list.

Figure 1: RAKwireless access point

NOTE

XXXX is the last 2 bytes of your RAK7244 WiFi MAC address. Connect to this Wi-Fi SSID using the password provided below. Take note also of the default IP address of the gateway provided below as this will be needed in connecting via SSH.

• Wi-Fi Password: rakwireless
• Default IP Address: 192.168.230.1

Raspberry Pi 4 Ethernet Port

You can also connect your PC with the gateway through an Ethernet cable. By default, the IP address of the gateway’s Ethernet interface is 192.168.10.10, so you need to set the IP address of your PC’s Ethernet to the same network segment, for example, 192.168.10.20.

• To do this on a Windows PC, go to Control Panel -> Network and Internet -> Network and Sharing Center and click on Ethernet.

Figure 1: Network and sharing center

• Click Properties, then choose Internet Protocol Version 4 (TCP/IPv4).

Figure 1: Ethernet properties

• By default, the PC will obtain an IP address automatically. Click Option Use the following IP Address and enter the IP address 192.168.0.10.20, then press OK.

Figure 1: TCP/IPv4 properties

Now, you should be able to access your gateway from your PC successfully using the IP address 192.168.10.10 through SSH.

Log in to the Gateway

Windows OS

SSH (Secure Shell) is typically used to log in to a remote machine and execute commands. There are a lot of free and good SSH Clients out there namely Putty, BitVise SSH Client, MobaXterm and many more. Feel free to choose one that fits your needs. But for this guide, you will be using Putty.

Figure 1: Putty Software for SSH in Windows

• If you have connected to the gateway through Wi-Fi AP Mode, the IP address is 192.168.230.1
• If you have connected to the gateway through Ethernet, the IP address is 192.168.10.10
• It will then prompt you to enter the username and password. The default username and password is provided below:
  • Username: pi
  • Password: raspberry

Figure 1: Command line after log in

Mac OS

Open the Terminal of Mac OS. Launch the Terminal application, which is found in /Applications/Utilities/ directory. But you can also launch it from Spotlight by hitting Command + Spacebar, typing Terminal, and then return.

Figure 1: Opening Terminal in Mac OS

Open the terminal of Mac OS. Enter root mode by typing the following command:

sudo -i

Linux OS

If the OS of your PC is Linux, you should do the same as the Mac OS, except for the root mode.

Accessing the Internet

Assuming you have successfully logged into your gateway using SSH. Enter the following command in the command line:

sudo gateway-config

You will now then see a page the same as Figure 11.

Figure 1: Configuration options for the gateway

1. Set pi password - used to set/change the password of the gateway.
2. Setup RAK Gateway Channel Plan - used to configure the frequency, on which the gateway will operate, and the LoRaWAN Server which the gateway will work with.
3. Restart packet-forwarder - used to restart the LoRa packet forwarder.
4. Edit packet-forwarder config - used to open the global_conf.json file, to edit LoRaWAN parameters manually.
5. Configure WIFI - used to configure the Wi-Fi settings in order to connect to a network.
6. Configure LAN - used to configure the Ethernet adapter settings.
7. Configure APN Name (optional) – used to configure the access point name of the mobile network.
8. Configure LTE Module (optional) – used to enable/disable LTE automatic dial-up.

NOTE

Points 7 and 8 can be found only on LTE versions of the gateway.

Connect through Wi-Fi

If you want to connect through Wi-Fi, it can easily be done with the Wireless capabilities of the Raspberry Pi 4 by choosing 5 Configure WIFI. By default, the RAK7244 WisGate Developer D4 Gateway works in Wi-Fi AP Mode.

For the gateway to connect to the router, it must work in Wi-Fi Client Mode.

Figure 1: Wi-Fi options configuration

There are 5 options to choose from in the Wi-Fi configuration menu:

1. Enable AP Mode/Disable Client Mode - the gateway will work in Wi-Fi Access Point mode after rebooting, while the Wi-Fi Client Mode will be disabled (this is the default mode).
2. Enable Client Mode/Disable AP Mode - the gateway will work in Wi-Fi Client mode after rebooting, while Wi-Fi AP mode will be disabled.
3. Modify SSID and pwd for AP Mode - used to modify the SSID and password of the Wi-Fi AP. Only works if the Wi-Fi AP mode is enabled.
4. Add New SSID for Client - this is used if you want to connect to a new Wi-Fi Network. Only works in Wi-Fi Client mode.
5. Change Wi-Fi Country - this is used to modify the resident country to match Wi-Fi standards.

warning

To enable Wi-Fi Client Mode, you have to disable AP mode first.

Once Wi-Fi AP Mode has been disabled by choosing 2 Enable Client Mode/Disable AP Mode, you can now then connect to a new Wi-Fi Network by choosing 4 Add New SSID for Client.

Figure 1: Add a new SSID

• Start by selecting your country of residence.

Figure 1: Selecting country of residence

• Enter the SSID of the network you want to connect.

warning

Make sure to input the correct Wi-Fi SSID and password or you will not be able to connect to the RAK7244 again via SSH in Wi-Fi AP mode. If stuck in this situation, follow the procedure listed in the Reverting to Wi-Fi AP Mode section, which is applicable for all Raspberry Pi based gateways to work again in Wi-Fi AP mode.

Figure 1: SSID of the network you want to connect

• Type the password. If there is none, leave the field empty.

Figure 1: Wi-Fi password

Connect through Ethernet

If you want to connect to the router through an Ethernet cable, do the following steps:

• In the main configuration menu, choose 6 Configure LAN. This will let you set up a static IP address for the gateway’s Ethernet adapter.
• Type a static IP address according to the IP address of the router you want to connect. The gateway and the router must be in the same network segment, otherwise, the connection will fail.
• By default, the IP address of the gateway's Ethernet is 192.168.10.10

Figure 1: Default gateway Ethernet IP address

• Then configure the IP address of the router. This is the LAN interface IP address of the router.

Figure 1: Router LAN IP address

• Press OK, and the success message will appear.

Reboot

Lastly, reboot the gateway using the command shown below and put it in the command line.

sudo reboot

After reboot, the gateway will connect to the router successfully through Ethernet.

Optional Configurations

The configurations under this section are only optional and situational.

Reverting to Wi-Fi AP Mode

If you have entered either or both incorrect Wi-Fi SSID and password in the Wi-Fi Client mode setup for the RAK7244 WisGate Developer D4 Gateway to connect to the router, follow this set of steps to work again in Wi-Fi AP mode and redo the setup.

• Remove the SD card from your RAK7244 WisGate Developer D4 Gateway and insert it into your PC. Your PC should be able to detect it.

Figure 1: Creating rak_ap file to your SD card

• Using your Command Prompt or Terminal, navigate to your SD card and type this command to generate the rak_ap file.

cd > rak_ap

• Check if the rak_ap file is created successfully. If so, re-insert the SD card into your RAK7244 WisGate Developer D4 Gateway, and it should work again in Wi-Fi AP mode.

Configuring the Gateway

Assuming you have successfully logged into your gateway using SSH, enter the following command in the command line:

sudo gateway-config

Then you will see a page like in Figure 20.

Figure 1: Gateway configuration options

1. Set pi password - used to set/change the password of the gateway.
2. Setup RAK Gateway Channel Plan - used to configure the frequency, on which the gateway will operate, and the LoRaWAN server which the gateway will work with.
3. Restart packet-forwarder - used to restart the LoRa packet forwarder.

Setup RAK Gateway Channel Plan

This menu allows you to select your LoRa frequency band and one of the two available networks server options by choosing 2 Setup RAK Gateway Channel Plan.

Figure 1: Choosing channel plan

You can choose one of two supported LoRa servers here: TTN or ChirpStack.

Server is TTN

Figure 1: TTN server

• TTN (The Things Network) - If you choose TTN as the LoRa server, you will see a page the same as shown in Figure 27. Visit LoRa Alliance Regional Parameters for more information on your local frequency plan. This will allow you to choose the correct plan.

Figure 1: Selecting the TTN channel plan

After choosing the correct frequency, a success message will appear, as shown in Figure 28.

Figure 1: Successfully changed the frequency

NOTE

When a channel plan is selected, the gateway is configured to connect to the nearest cluster to the region. If new clusters are presented, the channel plans will be updated. For now, the only available clusters are as follows:

• Europe: eu1.cloud.thethings.network
• Australia: au1.cloud.thethings.network
• North America: nam1.cloud.thethings.network

If you want to use TTN for LoRa network server, you can skip the If the Server is ChirpStack section and head to registering the gateway in TTN.

Server is Chirpstack

Figure 1: Chirpstack server

ChirpStack - If you choose Chirpstack as your LoRa server, you will see the following page with two options available:

• ChirpStack Channel Plan Configuration - used to configure your Regional Frequency Band.
• ChirpStack ADR Configure - used to enable/disable the Adaptive Data Rate (ADR) functionality.

Figure 1: Configure ChirpStack channel plan

First, select 1 ChirpStack Channel-plan configuration for configuring your frequency channel.

Figure 1: Regional frequency band option

Then set the IP address of the ChirpStack.

Figure 1: Default LoRaServer IP address

NOTE

The default IP address is 127.0.0.1. If you want to use an external LoRaServer, you need to set it to its IP address.

• If you have instead selected Chirpstack ADR Configure, you can enable/disable the Adaptive Data Rate (ADR) functionality.

Figure 1: Chirpstack ADR Enable/Disable

NOTE

If you want to use ChirpStack for LoRa network server, refer to the LoRaWAN Network Server Guide documentation under Connecting with ChirpStack section.
