Figure 11 – BMD-340 MAC Address on Label
The 6-byte BLE Radio MAC address is stored in the nRF52840 UICR at NRF_UICR_BASE+0x80 LSB first. Please
read the MAC Address Provisioning application note if you are not using the built in bootloader to avoid
erasing/overwriting the MAC address during programming. Important: If full memory protection is enabled,
the UICR cannot be read via the SWD interface. If performing a full-erase, the MAC can then only be recovered
from the 2D barcode and human-readable text.
