LoRa/LoRaWAN Gateway Kit

LoRa is a perfect long-range wireless solution to create low-power, wide area networks.So far we have released several “LoRa” boards such as Seeeduino LoRaWan and Grove LoRa Radio etc. However if you want to build you own LoRa network, there are 3 things that you should prepare to get started: a Gateway, at least one Node and a local server where you can monitor all your devices.

This kit provides all the basic elements you need: a Raspberry Pi 3, a Seeeduino LoRaWAN with GPS and a gateway & local server that allows you to collect and transfer data among all your LoRa nodes. By connecting the gateway with Seeeduino LoRaWAN and Grove modules, you can build your IOT prototype within minutes.

Regarding the gateway module RHF0M301, it is a 10 channel(8 x Multi-SF + 1 x Standard LoRa + 1 x FSK) LoRaWan gateway moduel with a 24pin DIP port on board, users can easily connect the RHF0M301 with PRI 2 bridge RHF4T002, adapter for Raspberry Pi 3 and RHF0M301. We also included a 868MHz antenna, an 8GB SD card and USB cables, Ethernet Cables and other accessories.

Caution

Please always plug 3.7V Lipo battery in case USB power supply is not sufficient. This wiki works for both 868MHz kit and 915MHz kit.

Software

Software Tool

In the following guide, below tools will be needed, please install it to your computer.

  • Arduino, portable serial tool, used to open the serial port of Seeeduino LoRaWAN with GPS (RHF76-052AM) and send AT commands to it.
  • PuTTY, terminal tool include both serial and SSH terminal, used to control Raspberry Pi.
  • Internet browser, used to access RHF2S001 integrated LoRaWAN server (It is recommended to use Chrome or Firefox).

Note

You may have your other favorite serial tools,of cause you can use them.However if you are not sure about your tools.Pleae use the ones we recommend.

Connect To Local Server

Step 1. Power up and connect to putty

a) First, make sure the serial tool and RPi (RHF4T002 Adapter) are connected correctly.

b) Plug FT232 tool to PC (If COM port is not recognized correctly, please refer to Virtual COM Port Drivers)

c) Open Device Manager of your PC to get the right COM port. Like COM15 for example. Configure ExtraPuTTY according to below picture (Speed 115200, others use defaults), click Open. As the gateway is still not opened, so there is nothing in the terminal.

d) Power the gateway up. Booting log will be showed in the PuTTY terminal, in the end it will prompt you to input your log in name. Please note it takes 1 or 2 minutes to get the prompt information.

e) Please use RHF2S001 default user name and password to log in. ( Username: rxhf, Password: risinghf ). Note, when input the password, there is no any echo

f) Connect RHF2S001 with router through ethernet cable

g) Run ifconfig to check the ip address and mac address.

IP is in the blue square, MAC address is in orange square (Format: b8:27:eb:xx:xx:xx)

Note

After you get the IP, it is recommended to login RHF2S001 again through SSH. Because SSH is faster (Ethernet than UART) and stable. We normally use serial tool to get the IP. Reopen PuTTY, use the SSH module to connect again.

To login through SSH, you need to fill in the Hostname with the IP address you've just got.And use port 22,choose the SSH connection type. Just leave the other options by default. Then simply click Open.

Step 2. Expand SD Card File System

By default, the image enables only 2GB for Raspbian System, it is recommended to expand to use the whole SD card (8GB or 16GB). Or the SD card will be full soon. Run below command in the PuTTY terminal to start raspi-config,

1
sudo raspi-config
Choose “Expand Filesystem”, when finished reboot to make it effect. Run below command in the PuTTY terminal to know the SD card capacity and usage.

1
df -h

Please refer to Raspberry Pi raspi-config tool instruction for details.Click here see more.

Step 3. Use RHF2S001 integrated LoRaWAN server

a) Connect Gateway with internal server

Run below commands in the PuTTY terminal, and check the status:

1
sudo systemctl status pktfwd
If pktfwd service is not active, run below command to start it:

1
2
sudo systemctl enable pktfwd
sudo systemctl restart pktfwd
