No, the default MAC address that is programmed into the FICR registers of the nRF51822 during production is a randomly generated static address. From the Bluetooth Core specification, Volume 6 Part B, Section 1.3 DEVICE ADDRESS
A static address is a 48-bit randomly
generated address and shall meet the
following requirements:
The two most significant bits of the static address shall be equal to
‘1’
All bits of the random part of the static address shall not be equal to
‘1’
All bits of the random part of the static address shall not be equal to
‘0’
A device may choose to initialize its
static address to a new value after
each power cycle. A device shall not
change its static address value once
initialized until the device is power
cycled.
