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. We use 868MHZ kit

in this wiki, but this wiki works for both 868MHz kit and 915MHz kit.

Features¶

•Low power consumption & wide area

Getting Started¶

Hardware¶

Interfaces overview¶

Since there are many interfaces here, it is necessary to know the capabilities of

these interfaces. Please refer to the following figure for

details.

•❶Micro-USB Input: The whole system use this Micro-USB interface for

power supply.

•❷USB HOST Connector: Output power to supply for Raspberry Pi

•❸Raspberry Pi power input: Input power for Raspberry.

•❹HDMI: HD digital video output interface.

•❺Headphone jack: 3.5mm Headphone jack

•❻Ethernet interface: You can use the Ethernet interface to connect this

system to the Internet. Or you can use Wifi after you configured the wireless

network.

Hardware connection¶

•Step 1. Plug Gateway module RHF0M301–868 into PRI 2 Bridge RHF4T002.

•Step 2. Plug PRI 2 Bridge RHF4T002 into Raspberry Pi 3.

•Step 3. Connect ❷and ❸via the 20cm Micro-USB cable.

•Step 4. Connect the USB to UART Adapter to the GPIO of Raspberry Pi 3.

Please connect them as the picture shown below.

•Step 5. Plug the USB to UART Adapter into your PC.

•Step 6. Connect ❶with 5V/2.1A Standard Adapter via 100cm Micro-USB

cable.

When you finished all the steps, the whole system should be like the picture below.

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 ifyou 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

toVirtual 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,

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.

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:

sudo systemctl status pktfwd

If pktfwd service is not active, run below command to start it:

sudo systemctl enable pktfwd

sudo systemctl restart pktfwd
