Preprogrammed MAC address

[Lars]

Hi. Our company is designing a new device using the nrf52832 chip for BLE communication with other equipment from our Company.

Does the chip come with a factory preprogrammed MAC address ? If Yes: Is the address in a predefined "Nordic" range or is it completely random ? Can we use the preprogrammed MAC address as is, or do we need to change it ?

Our Company is currently producing other devices with MAC addresses from our own MAC address range. Can Nordic deliver the nrf52832 chips with preprogrammed MAC addresses from our own range ?

Thanks, Lars

The chips come with a random static address assigned. There are many gap address types defined in the BLE spec.

You can read about them here: devzone.nordicsemi.com/.../

If you wish to use a public static address, those must be purchased since they are an allocated resource.

I should have also stated that, yes you can deploy with the random static address the device comes with. It is very common to do this.

And, I do not believe Nordic will deliver chips with a custom address to you. Maybe for $$$$$! :) It is fairly simple to assign your own address. Normally this would be done during functional test/programming just before shipment.
