4.2.3 IEEE 802.15.4 (Thread and Zigbee)
IEEE 802.15.4 based protocols, such as Thread and Zigbee, on the BMD-341 are not implemented
using a SoftDevice. Nordic Semiconductor provides an IEEE 802.15.4 compliant MAC stack which
does not require a SoftDevice to be loaded to operate. Nordic Semiconductor also provides
pre-compiled Thread and Zigbee stacks. See the Nordic Semiconductor SDK for more information on
developing applications that utilize IEEE 802.15.4. Both allow for concurrent operation with Bluetooth
low energy SoftDevices.
4.3 Bluetooth address
The BMD-341 modules are preprogrammed from the factory with a unique public Bluetooth address
stored in the UICR. The u-blox organizationally unique identifier is 6C:1D:EB. This is combined with
the last six characters of the Bluetooth address that are printed on a 2D barcode and in human-
readable text on the module label, as described in section 5.3 below.
