MAC address burning on nRF52840 module

[vinay_kumar]

Hi Team,

We want to write our own MAC address on nRF52840 module. It's a production level MAC address i.e. it is fixed MAC address cannot be overwritten. What is the procedure I need to follow? Is there anything like OTP memory in nRF52840. Where I need to write the permanent MAC address. We already tried with software, it is successfully done but the issue that MAC address is overwritten. So as I said previously we need to write permanent MAC address which is for production level not for testing level. 

Can anyone please help to close this issue.

Thanks,

Vinay
