How to Configure BLE MAC Address on a Custom RW610 Board

Hi NXP Team,

I have a custom RW610 board on which I am testing one of the BLE SDK example projects.

When the board starts advertising, the BLE MAC address is displayed as 88:88:88:88:88:88. However, when I tested the same SDK example on the FRDM-RW612 EVK, it advertised with a unique Bluetooth MAC address.

I would like to understand:

How is the BLE MAC address assigned on the RW610?
How can I configure or program a unique BLE MAC address for my custom RW610 board?
Is the MAC address expected to be stored in external flash or generated by software?
Are there any SDK APIs or board configuration changes required to set the BLE MAC address?

Any guidance or references would be greatly appreciated.

Thanks & Regards,
Prathyush.

Hi,

The FRDM-RW612 already comes with a programmed BD address.

For your custom board, you will need to program a BD address into the OTP memory.

Please refer to the Calibration Structure for RW61x application note: https://www.nxp.com/docs/en/application-note/AN13639.pdf

For testing purposes, you can use a static BD address. For example, you can create and select one using the id-create command from the Bluetooth shell. Please refer to UM11799 for additional details.

Daniel.
