Accessing Your Gateway

After burning the firmware image onto the SD Card, make sure you have inserted the SD Card into the RAK7243C WisGate Developer D3+ Gateway and have the LoRa, GPS, and LTE 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 3B+, you should connect the LoRa, GPS, and LTE 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 that 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 RAK7243C Wi-Fi 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 3B+ 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
