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 .
