Some questions for MAC address of nRF7002 companion IC

[Jeffery]

Hi

1. 

A. nRF7002 DK(NRF5340+NRF7002)

B. Our PCBA(NRF5340+NRF7002)

We found same application code flash to both. Sample A can work. Sample B can't work and stuck

at error initially. The log shows empty MAC address. So, for new NRF7002, the job to program

MAC address to OTP belongs to manufacturer side? Or, Nordic can fill the MAC address at OTP before shipping?

2.

About the MAC address of nRF7002, is it necessary to apply in Wifi alliance in advance?

We cannot find these kind of information as similar as MAC address in BLE SIG. Something as public or private address.

Hi Jeffery,

We only assign MAC addresses for products, i.e. kits. ICs are shipped without MAC addresses, allowing you to utilize your own company identity in the MAC addresses. MAC addresses are administered by IEEE. You can refer to this webpage - MAC addresses. It is not necessary to program MAC address in OTP, but a valid MAC address is required for a proper interface operation. You can refer to program MAC address for information how to program MAC address. You can also use this alternative method if MAC address is not programmed in OTP.

Best regards,
Dejan
