2.2.2.2.3 Build software
In the mbed CLI, compile software by using the name of the object created in the targets.json file as parameter
to the board flag. In the EVK-NINA-B1 example, the build command will be:
“mbed compile –t GCC_ARM –m EVK_NINA_B1”.
2.2.3 Wirepas connectivity software
The NINA-B1 series module can also be used together with the Wirepas software stack. This will enable the
NINA-B1 module to be used in a big scale true mesh environment.
The Wirepas connectivity software is third party software licensed from Wirepas.
For more information about the Wirepas connectivity software, contact the u-blox support for your area as listed
in the Contact section.
2.3 Flashing the NINA-B1 module
It is possible to reflash the NINA-B1 module using either the UART or SWD interface whenever a new version of
the u-blox connectivity software is available or when using a custom application.
Flashing of u-blox connectivity software is normally done over UART. If the flash is erased or
any other software is flashed on the NINA-B1 module, then the SoftDevice and the u-blox
bootloader must be flashed over SWD before the u-blox connectivity software can be flashed
again. See section 2.3.2 for more information.
2.3.1 UART flashing
To use the UART interface, the module must have a bootloader that supports flashing over UART. The u-blox
connectivity software v2.0.0 and later includes a bootloader that can flash over UART.
NINA-B1 modules with u-blox connectivity software v1.0.0 can be flashed using the SWD
interface only and not the UART interface. See section 2.3.2 for flashing instructions.
The u-blox connectivity software for UART flashing contains two separate .zip files:
1. One zip file contains the application and
2. Another contains the bootloader and SoftDevice as listed below:
• Application – NINA-B11X-FWx.x.x.zip
• Bootloader and SoftDevice – NINA-B11X-BOOTx.x.x_SDx.x.x.zip
It is critical that both the zip files are flashed during an update and that the zip file that
contains the bootloader and the SoftDevice is flashed first.
