CC2651R3SIPA: Does CC2651R3SIPA include factory-programmed MAC address？

Toshio Katsura

Tool/software:

We have purchased the CC2651R3SIPA module from an authorized distributor and are currently integrating it into our BLE product by mounting it on our custom PCB.

We would like to confirm the following regarding the MAC address:

1. Does the CC2651R3SIPA module include a factory-programmed MAC address (IEEE EUI-64)?
2. If so, is the MAC address assigned by Texas Instruments?
3. Is it acceptable to release our BLE product using the factory-programmed MAC address, or is it recommended to assign our own MAC address (e.g., using an IEEE-registered OUI)?

Because our company don't have IEEE Registration for EUI-64.

Yes, each device comes with unique IEEE address, allocated to the respective TI device.

Please see "MAC IEEE 802.15.4 Address" in section "11.4.1 FCFG1 Registers" of this document: https://www.ti.com/lit/pdf/swcu191

It depends what you need to use this unique address for. If you just need a unique device ID, then I think using the address is fine.

However, if randomness is desired, please note these addresses do follow some format (e.g. first few bytes may be the same across CC2651).

Thanks,
Toby
