Software update
NORA-W36 u-connectXpress software includes a bootloader for flashing the module over the UART
interface. The file download uses standard XMODEM protocol. You can update the software using the
u-blox s-center 2
or using third-party Terminal software like TeraTerm.
u-connectXpress software can be downloaded at speeds of up to 3 Mbps over the UART interface.
The XMODEM-1K mode is recommended for maximum download speed.

benefit from bug fixes and security improvements. Download the latest software version at
Use s-center 2
or third-party Terminal software like Tera Term to update the software.
4.2.1
Updating with s-center2
client software provides a convenient tool with which to configure u-blox standalone
modules. It runs on PCs running Windows 10 or later and is available for download here
To flash the module using s-center2:
1.
Start
s-center 2
2.
Select
your workspace
and
your device
like
NORA-W36
3.
Click on
Configure
and select the software binary file.
4.
Click on
Start
to begin the software update.
4.2.2
Updating with Terminal
It is possible to start the XMODEM protocol used for file transfer with an AT command or using the
bootloader.
Updating using AT command
1.
Connect to the module using Tera Term, for example, and set the port to 115 200 baud rate, 8-bit
data without parity, 1 stop bit, and no flow control.
2.
Enter the AT command
AT+USYFWU=0,115200.
The module responds with
OK
and enters the
bootloader.
3.
When the
bootloader displays “
>
CCCC…
”
the module is ready to receive the software binary file.
4.
Send the file using XMODEM protocol.
5.
The module restarts with
+STARTUP
when the file transfer is complete.
Updating using the bootloader
1.
Enter the bootloader by either:
a)
Entering AT command
AT+USYFWU=1,115200
b)
Setting GPIO pins,
SWITCH_1
and
SWITCH_2
, low during power up or module reset. The
bootloader prompt “
>
” is displayed in the Terminal when the bootloader mode has started, as
shown in
. The bootloader times out after 10 seconds if no command is sent.
2.
Enter the command “
x
”
to start XMODEM and set the bootloader in file transfer mode.
3.
When the bootloader di
splays “
CCCC…
”
the module is ready to receive the software binary file.
4.
Send the file using XMODEM protocol.
5.
An OK response indicates a successful file transfer.
6.
Enter command “
q
” to restart the module
.
