2.2 s-center evaluation software
u-blox s-center client software provides a convenient tool with which to configure u-blox standalone
modules. It runs on PCs running Windows XP onwards (x86 and x64) with Net Framework 4.5 or later
and is available for download from www.u-blox.com. For further information about how to use this tool,
see the s-center user guide [8].
2.3 SDK for open-CPU modules
As NINA-W10 open-CPU modules are delivered without flashed software, you develop your
application design using the utilities and device-level APIs supported by the module chipset supplier.
The ESP-IDF Software Development Kit is available from the Expressif website. It bundles the Wi-Fi
stack and the broad range of drivers and libraries necessary for building your development
environment. See also section 2.7.
Figure 7 shows the architecture of NINA-W10 open-CPU software in relation to the MCU, transceiver
and ESP-IDF SDK.

2.4 Updating NINA-W13 and NINA-W15
NINA-W13 and NINA-W15 u-connectXpress software can be flashed and updated directly from the
host or s-center. The flash procedure uses the XMODEM protocol.
The following pins should be made available as either headers or test points to flash the module:
• UART (RXD, TXD, CTS, RTS)
• Bootstrap pins 25 and 27
• RESET_N
• SWITCH_1 and SWITCH_2
