MAC address look up on SIG website

[LeonWu]

Hi team,

My customer is evaluating nRF52810 in their project, and they come up with some questions regarding chip MAC address:

1. They understand that chip MAC address is randomly generated during mass production, and each MAC address is qualified by SIG and unique, for most cases. They are asking if they can look up MAC address and figure out manufacture information on SIG website?

2. If they can look up on SIG website, can they have the link for public? Or it must be SIG members to get access.

Thanks!

Hi Leon,

The nRF does not have a public MAC address. We only provide set of random numbers in the FICR, DEVICEADDR[0] and DEVICEADDR[1] which can be combined as a random static address. This is not qualified in any way. There is no way to look this up on the SIG website.

The alternative would be a public address, where the range is registered with the SIG. This is not something we provide, but the customer can buy a range from the SIG and use it in their devices. It does not add real value in most projects though, as the random address is unique for all practical purposes.

Hi Einar,

Thanks for your reply, already sync with customer. BTW, do we have any web link regarding buying address from SIG? Or any guideline?

Thanks!

Hi Leon,

We do not have any information about it, but the SIG has an overview here, which includes a link to IEEE.

Hi Einar,

If customer bought SIG MAC address, do we have the guideline regarding how should they program into our chip?

Thanks!

Hi Leon,

We do not have any official guideline for how to program the public MAC address into the chip, but I will outline how they can do it:

1. Program the unique MAC address to flash during production. This could typically be placed in UICR, but that is not a requirement.
2. Configure the SoftDevice to use the MAC address by calling sd_ble_gap_addr_set() at application startup (after initializing the SoftDevice but before using any other BLE functionality).
