2.5 Updating u-connectXpress software with s-center
The u-connectXpress software, flashed into NINA-W13/W15 modules prior to delivery, is used to
validate the hardware, bootloader, and the binary image. The u-connectXpress software runs only on
validated hardware.
Updates of the u-connectXpress software is available for download from www.u-blox.com. The
software is delivered in a zip container file, for example,
NINA-W1xX_SW1.0.0.zip.
To upload the latest u-connectXpress software to the module:
1. Download and unpack the zip container,
NINA-W1xX_SW1.0.0.zip, to your Windows workstation.
2. Open the s-center client software.
3. From the client, navigate to the .json file in the unpacked u-connect archive and select Update.
The s-center handles the download using information contained in the
*.json file without any
further interaction is needed from the user. See also Figure 8.
Figure 8: Software Update using s-center
☞ Secure boot functionality is supported in u-connect v4.7 and above.
☞ u-connectXpress cannot be installed on NINA-W10. For information on how to install applications
on NINA-W10, see section 2.7 and 2.8.
2.6 Updating u-connectXpress software from host
To manually start the download using a software without using s-center, e.g. from a host
microcontroller, use the following AT commands to start updating the NINA-W13/W15 u-
connectXpress:
AT+UFWUPD=<mode>,<baud>,<image id>,<image size>,<base64 encoded signature>,<image
name>,<flags>
Sample parameters that can be used while doing the flash update is provided below:
AT+UFWUPD=0,115200,0,651840,jzlRIkg37ir/pVpDKVrPot2ZdsaNvUtSYP2pDAUVJc7iQI9yzIo8V

When a “C” character is received from NINA-W13/W15, the XMODEM download is ready to begin from
the host.
