leaps_mac_addr_get
Get the MAC address list used by the device. The device uses either the address specified by the user or the default address. The default MAC address for each interface can be changed only once by calling leaps_mac_addr_set_once in which case it is written to OTP memory and becomes a new default MAC address. The user can set a custom MAC address by calling leaps_mac_addr_set. The default MAC address can be recovered by factory reset (see leaps_factory_reset) after being modified by the user. The device uses fixed mapping of the MAC address in list to the particular interface as follows:
UWB
BL
Ethernet
Wi-Fi
The BLE address can be Random BLE address or Public BLE address. If a particular interface is not supported, the corresponding MAC address in the list is empty.
(none)
err_code
type_0: ? 8-bit unsigned integer ? (type describing the MAC address at index 0 in the list)
mac_addr_0: ? 48-bits value ? (little endian)

T_0, T_1, T_2, T_3 describe the MAC address status.
0 - Empty MAC address
1 - Default MAC address from OTP memory.
2 - User specified MAC address
3 - Mutable default MAC address which can be rewritten only once using leaps_mac_addr_set_once.
P_1 is set if the BLE address is the Public BLE address. The flag is cleared if the BLE MAC address is random, refer to BLE specification for more information on BLE address types.
