Bluetooth Device (Mac) Address And Other Production Data - Ublox NORA-B1 Series System Integration Manual

2.2 Bluetooth device (MAC) address and other production data

NORA-B1 modules are programmed from the factory with a unique, public Bluetooth device address
stored in the OTP[0] and OTP[1] registers of the User Information Configuration Registers (UICR) in
the application core. The device addresses are duplicated in the CUSTOMER[0] and CUSTOMER[1]
registers in the UICR of the network core.
The Bluetooth device address consists of the IEEE Organizationally Unique Identifier (OUI) combined
with the hexadecimal digits that are printed within a 2D data matrix, as described in the Labeling and
ordering section of the product data sheet [1]. The Bluetooth device address is stored in little-endian
format. The two most significant bytes of the OTP[1] and CUSTOMER[1] registers are unused and
assigned the value 0xFF to complete the 32-bit register.

If write-protection is not enabled, the address can be read and written through the nRF Connect SDK
utilities. See also reference [16].
$ nrfjprog.exe --memrd 0x10001080 --n 8
The memory area can be saved and, if the flash is erased, written back later using the
loadbin utilities in the SEGGER J-link tool suite.
The entire UICR memory area can hold other valuable information. Use the following commands to
save the entire UCIR memory area:
$ nrfjprog.exe --readuicr uicr.hex
...
$ nrfjprog.exe --program uicr.hex
For additional information and instructions on saving and using the public Bluetooth device address,
see reference [7].
