Hi,
I'm looking for the public mac address for nrf52840, and i find out that the mac address is located inside the register FICR->DEVICEADDR[0] and DEVICEADDR[1].
DEVICEADDR[0] = 0xeb4b70e6
DEVICEADDR[1] = 0xc47eacdb
if we combine the two register it become 0xacdbeb4b70e6.
i saw in this post that the first MSB of the address should be 11 How to get 6 byte mac address at nrf51822
which make the MAC address look like this one : 0xecdbeb4b70e6.
is it the correct public mac address ?
when i tried to search for the address vendor on different website and all of them they said no vendor exist for this MAC address. like this website https://www.macvendorlookup.com/
i tested this website with different BLE manufacture and it always tell me the correct manufacture.
there is another website that list all the MAC ID vendor per company and for nordic semiconductor i got only one assigned MAC which is F4:CE:36:xx:xx:xx . other manufacture has +300 assigned mac range.
