Alternatively, the MCUXpresso Config Tools is an integrated suite of configuration tools that help
guide users to quickly build a custom SDK and leverage pins, clocks and peripherals to generate
initialization C code or register values for custom board support, the tool is available as a standalone
for MAC OS, Linux and Windows, as well as a web based version.
For the EVK-NINA-B5 there are some basic pinmux files available in the u-blox open CPU GitHub
repository
[21] .
☞
If using the MCUXpresso IDE, no additional download of Config Tools is required.
4.2 Bluetooth device (MAC) address and other production data
During the production of the NINA-B50 module the information in Table 8 is stored on the NINA-B50
flash memory.
Parameter Size (bytes) Remark
Identification word 10 “PROD_DATA:”
Bluetooth address 6
Unique, public Bluetooth device (MAC) address that
can be used by the customer application.
IEEE 802.15.4 address 8 MAC address
32 MHz crystal trim value 1 Module internal crystal, trim value set by u-blox
32 kHz crystal capacitance
value 1
☞
Needs to be set by customer if using external 32
kHz crystal.
u-blox type number 16
u-blox serial number 8
Table 8: Production parameters stored on NINA-B50
The parameters are stored in the PROD_DATA_BASE_ADDR register.
Example code for reading the parameters stored in u-blox production can be found on the u-blox open
CPU GitHub repository
[21] , and a C language representation for the parameters can be found in
Figure 14 .

The API call
NV_ReadHWParameters()
(SDK 2.12.5) is used to read these parameters.
