Extracting DevEUI and AppEUI from the LoRa® module
The I-NUCLEO-LRWAN1 expansion board uses the serial interface (CN8 pin 1 (Tx) and pin 2 (Rx)) shown in
Figure 19 for the AT command console. The default serial configuration is:
• Baud rate: 115200
• Data: 8 bit
• Parity: none
• Stop: 1 bit

Alternatively, since preloaded firmware reads the DevEUI and AppEUI parameters of the module and saves them
to the internal data memory of the STM32L073RZT6 (Data Memory Bank 1 of the NUCLEO-L073RZ Nucleo
board), the user can extract both parameters by reading the data memory using the STM32 ST-LINK Utility
(STSW-LINK004) or the STM32CubeProgrammer (STM32CubeProg).
Follow these steps to extract DevEUI and AppEUI using the STM32 ST-LINK Utility:
1. Download STM32 ST-LINK Utility (STSW-LINK004) from STMicroelectronics web site and install it
2. Connect the NUCLEO-L073RZ Nucleo board with the personal computer by means of the USB
3. Open a Windows® Command prompt and set the path for the STM32 ST-LINK Utility:
SET PATH=%PATH%;C:\Program Files (x86)\STMicroelectronics\STM32 ST-LINK
Utility\ST-LINK Utility
4. Read DEvUI and AppEui using STM32 ST-LINK Utility CLI command:
– For DevEUI: ST-LINK_CLI.exe -c swd ur -r8 0x08080000 0x08
– For AppEUI: ST-LINK_CLI.exe -c swd ur -r8 0x08080008 0x08
The addresses in the CLI commands are for Data Memory Bank 1 of the NUCLEO-L073RZ Nucleo board.
Note: The STM32 ST-LINK Utility (STSW-LINK004) GUI can also be used to read the data memory of the NUCLEO-
L073RZ.
A similar process is possible using the STM32CubeProgrammer (STM32CubeProg). Refer to
STM32CubeProgrammer documentation on www.st.com.

6 Gateway setup and configuration
The gateway is a simple packet forwarder based on the Semtech packet forwarder protocol. It needs to be
configured to the desired frequency band and LoRaWAN® network server among other parameters that are
reconfigurable. This can be done by sending AT commands using the Virtual COM port of the Nucleo board.
This section describes the steps to setup the gateway and reconfigure it to the desired frequency band and
network server that supports the Semtech packet forwarder protocol.
6.1 Gateway setup
1. On the NUCLEO-F746ZG board, verify the jumper settings:
– JP1 (PWR-EXT) OFF
– JP3 (power source) on VIN-5V
– JP5 (IDD) ON
2. Connect the NUCLEO-F746ZG board to a network router with an Ethernet cable through Ethernet connector
CN14.
Make sure that the router has DHCP service and Internet access (no password).
3. Connect the antenna to the antenna connector (CN2) (for P-NUCLEO-LRWAN3).
4. On the LoRa® gateway expansion board, connect an external 5 V supply through its USB Micro-B connector
(CN1) to power the whole board.
Important: power supply must be connected to the gateway shield USB port and not with the Nucleo USB
port.
On the Nucleo board, green LED LD6 (PWR) and LD4 (COM) light up. On the gateway shield, the green
LED lights up.
Note: a USB wall adapter/charger is required to power the gateway.
5. To view the gateway MAC address, channel frequency and status, connect the NUCLEO-F746ZG board with
a personal computer by means of a USB Type-A or USB Type-C® to Micro-B cable through USB connector
CN1. View the parameters using a terminal emulation software such as Tera Term.
6. Allow the personal computer to enumerate and install the USB drivers.
Take note of the Virtual COM port number assigned to the board.
7. Open a terminal emulation software such as Tera Term and configure it with the following settings:
– Port: (Virtual COM port number assigned to the board from step 6)
– Baud rate: 115200
– Data: 8 bit
– Parity: none
– Stop: 1 bit

The ST Nucleo LoRa GW user guide from RisingHF ([3]) details the reconfiguration of the gateway using AT
commands.
To change the frequency channels, use the AT+CH command. Reset the board for the new settings to take effect.
At startup, firmware checks for the compatibility of the frequency band setting versus RF hardware. It displays a
warning if the setting is not compatible with the hardware.
Set the packet forwarder channels as follows:
UM2587 - Rev 2
page 30/51
UM2587
Configuring the gateway to use a different frequency band
• Format:
AT+CH=0~7,freq,radio // Set multi SF LoRa channel
AT+CH=8,freq,radio,sf,bw // Set standard LoRa channel
AT+CH=9,freq,radio // Set FSK channel
AT+CH=0~9,0 // Turn off a channel
AT+CH=0~9,OFF // Turn off a channel
AT+CH=band // Set to predefined channel plan
• Return:
+CH: 0~7, freq, radio, SF7/SF12, BW125KHz (LORA_MULTI_SF)
+CH: 8, freq, radio, SFx, BWxxxKHz (LORA_STANDARD)

Changing the LoRaWAN® server, MAC address, and gateway EUI
By default, the gateway is configured to forward packets to Loriot network server. It is possible to use other
servers that support the Semtech packet forwarder protocol. Use the following commands to change the settings:
• AT+PKTFWD
Changes the packet forwarder server address and port. Refer to [3] for some of the available server
addresses and uplink/downlink ports.
AT+PKTFWD=address,port_up,[port_down]
– Example for Loriot AP1 server – Singapore:
AT+PKTFWD=ap1.loriot.io,1780,1780
+PKTFWD: ap1.loriot.io, 1780, 1780
• AT+MAC
Changes the MAC address if needed.
AT+MAC=mac_address
– Example:
AT+MAC=001122334455
+MAC: 00:11:22:33:44:55
• AT+MEUI
Sets the gateway EUI by adding paddings at specific positions of the Ethernet MAC address.
AT+EUI=pos0,val0_hex,pos1,val1_hex
– Example:
AT+MAC
+MAC: 00:11:22:33:44:55
AT+EUI=3,FF,4,FF
+EUI: 0, FF, 1, FE, 001122FFFF334455

This section describes how to register the sensor device and gateway to the network server. The following
network server providers are supported:
• Loriot
• The Things Network
7.1 Loriot network server setup
Go to the Loriot website at www.loriot.io/ and create an account on the preferred Loriot server, such as EU1 –
Frankfurt, Germany, or AP1 – Singapore. Whichever Loriot server is used, the gateway needs to be configured
to forward packets to the correct server address. Refer to Section 6.3 Changing the LoRaWAN server, MAC
address, and gateway EUI on how to change the server address. The Loriot free account allows the registration of
a limited number of devices and gateway with limited features for evaluation purpose. Refer to the Loriot website
for more details about their offer.
The default network server setting for the P-NUCLEO-LRWAN2 gateway is: eu1.loriot.io. The corresponding
Loriot network server that the user needs to create an account from must be EU1 – Frankfurt, Germany.
The default network server setting for the P-NUCLEO-LRWAN3 gateway is: cn1.loriot.io. The corresponding
Loriot network server that the user needs to create an account from must be CN1 – Shenzhen, China.
If the nearest server is desired, the gateway LoRaWAN® server setting need to be changed accordingly to the
new server address and port.
Both the LoRa® sensor device and gateway need to be registered to the Loriot network server. Log in to start
registering the sensor device and gateway.
