Raspberry Pi OS (Lite)
If you use the system image provided by us, after the system starts, you will automatically log in with the user name pi, and the default password is raspberry.

If you use the official system image, and the image is not configured before burning, the configuration window will appear when you start it for the first time. You need to configure the keyboard layout, set the user name and the corresponding password.

• Set the configuration keyboard layout
  

• Creat new user name
  

Then set the password corresponding to the user according to the prompt, and enter the password again for confirmation. At this point, you can log in with the user name and password you just set.

Use SSH
All the images we provide have turned on the SSH function. If you use the official image, you need to turn on the SSH function.

Use raspi-config enable SSH

sudo raspi-config

1. Choose 3 Interface Options
2. Choose I2 SSH
3. Would you like the SSH server to be enabled? Select Yes
4. Choose Finish

Add Empty File To Enable SSH
Put an empty file named ssh in the boot partition, and the SSH function will be automatically enabled after the device is powered on.

Get The Device IP

• If the display screen is connected, you can use the ifconfig command to find the current device IP.
• If there is no display screen, you can view the assigned IP through the router.
• If there is no display screen, you can download the nmap tool to scan the IP under the current network. Nmap supports Linux, macOS, Windows and other platforms. If you want to use nmap to scan the network segments from 192.168.3.0 to 255, you can use the following command：

After waiting for a period of time, the result will be output.

Wiring Guide

Internal I/O
micro-SD Card
ED-GWL501 is internally integrated with Raspberry Pi Zero 2 W, which has a micro SD card slot. Please insert the micro SD card of the burned system face up into the micro SD card slot.

Software Operation Guide

Button
ED-GWL501 has one user-defined button, the screen printing on the shell is Setup, which is connected to the GPIO23 pin of the CPU. By default, it is high, and when the key is pressed, the pin is low.

We use the raspi-gpio command to test, and query the GPIO23 pin when the key is not pressed.
raspi-gpio get 23
GPIO 23: level=1 fsel=0 func=INPUT

LED Indication

ED-GWL501 has an RGB three-color LED indicator. Corresponding to the GPIO pin of CPU is as follows

When the GPIO output is low, the corresponding LED is valid. We use the raspi- gpio command to operate, and the configuration parameter is op, which means output setting, dl setting pin is low level, and dh setting pin is high level.

• LED is blue
• LED is green
• LED is red
• LED is yellow

Ethernet Configuration
ED-GWL501 has an adaptive 10/100Mbsp Ethernet interface, with the screen- printed logo: Ethernet, which is extended by the built-in USB interface. The interface address of the network card is /sys/class/net/usb0. The official system of Raspberry Pi uses dhcpcd as the network management tool by default. Setting static IP can be set by modifying/etc/dhcpcd.conf. For example, set usb0, and users can set wlan0 and other network interfaces according to their different needs

WiFi
ED-GWL501 support 2.4 GHz IEEE 802.11 b/g/n WiFi。 The official system of Raspberry Pi uses dhcpcd as the network management tool by default

1. Choose 1 System Options。
2. Choose S1 Wireless LAN。
3. Select your country in the Select the country in which the pi is to be used window, and then select OK. This prompt only appears when setting up WIFI for the first time.
4. Please enter SSID，input WIFI SSID.
5. Please enter passphrase. Leave it empty if none，input password, then restart

Bluetooth
ED-GWL501 supports Bluetooth 4.2 and Bluetooth Low Power Consumption (BLE), and the Bluetooth function is turned on by default. Bluetoothctl can be used to scan, pair and connect Bluetooth devices. Please refer to the ArchLinuxWiki-Bluetooth guide to configure and use Bluetooth.

Usage

• Scan
• Find
• Trust device
• Connect device
• Disconnect device

GPS
The ED-GWL501 gateway integrates L76K GPS module, which is connected with UART0 serial port of CPU. The module reports GNSS information through NMEA 0183 general protocol output statemen

• $BDGSV Visible Beidou satellite information
• $GNRMC Recommended GNSS data
• $GNVTG Relative ground heading and speed information
• $GNZDA Time and date, UTC format
• $GPTXT Text transmission
• $GNGGA Multi-satellite joint positioning data
• $GNGLL Geographical location, latitude and longitude
• $GNGSA GNSS accuracy factor and effective satellite
• $GPGSV Visible GNSS satellite

Checks Ser2net Port Forwarding Service

Open u-center，Choose Receiver->Port->Network connection->New…

Enter your device IP and port number 2000.

You will see the GPS positioning information immediately after the configuration is completed.

If the Fix Mode is displayed as No Fix, it means that the positioning failed, which is usually caused by the antenna being indoors. Please put the module or antenna outdoors for testing.

NOTE:For the first time, it takes about 30 seconds to locate successfully when there is no large building outside. If the weather conditions are bad, it may take longer or it may not be possible to locate it.

LoRaWAN
ED-GWL501 supports LoRaWAN open source service platform ChipStack, please refer to the following steps for installation and configuration.

Install LoRa Service And ChirpStack Client
We install it by APT.

• Add edatec APT warehouse
• Install ChirpStack
• Modify config.txt

Configuring LoRa Service

chirpstack-gateway-bridge Configuration
You can use nano to edit the configuration file chirpstack-gateway-bridge.toml

This configuration provides a Semtech UDP packet-forwarder backend and

integrates with a MQTT broker. Many options and defaults have been omitted

for simplicity.

See https://www.chirpstack.io/gateway-bridge/install/config/ for a full

configuration example and documentation.

Gateway backend configuration.

[backend] # Backend type.
type=”semtech_udp”

Semtech UDP packet-forwarder backend.

[backend.semtech_udp]

ip:port to bind the UDP listener to

Example: 0.0.0.0:1700 to listen on port 1700 for all network interfaces.

This is the listener to which the packet-forwarder forwards its data

so make sure the ‘serv_port_up’ and ‘serv_port_down’ from your

packet-forwarder matches this port.

udp_bind = “0.0.0.0:1700″

Integration configuration.

[integration] # Payload marshaler.

This defines how the MQTT payloads are encoded. Valid options are:

* protobuf: Protobuf encoding

* json: JSON encoding (easier for debugging, but less compact than

‘protobuf’)
marshaler=”protobuf”

MQTT integration configuration.

[integration.mqtt] # Event topic template.
event_topic_template=”eu868/gateway/{{ .GatewayID }}/event/{{ .EventType }}”

Command topic template.

command_topic_template=”eu868/gateway/{{ .GatewayID }}/command/#”

MQTT authentication.

[integration.mqtt.auth] # Type defines the MQTT authentication type to use.

Set this to the name of one of the sections below.

type=”generic”

Generic MQTT authentication.

[integration.mqtt.auth.generic] # MQTT server (e.g. scheme://host:port where scheme is tcp, ssl or ws)
server=”tcp://127.0.0.1:1883″

Connect with the given username (optional)

username=””

Connect with the given password (optional)

password=””

Reboot
