MAC ADDRESS OF NRF52832 CHANGE WHEN IT RESET.

[fenil.patel]

HI,

  I am using nrf52832 with sdk15.2.0 and softdevice s132. I face some issue related MAC address of nrf52832.

when I reset the sensor MAC address of the sensor change every time. every time mac address set randomly. and I flash the same code then also MAC address change.

but the interesting thing is that when I flash same code to other nrf52832 MAC address remain the same.

I face this issue with some selected nrf52832 sensors.

If anyone had the same issue then let me know.

Thank you.

Can I retrieve the original mac address of the nrf52832 sensor?

Hi Fenil, 

Could you let me know which firmware you are using ? 

If your firmware choose to use Random resolvable address instead of random static address (the default one) then address will be different on each start up. 

Could you test using one of our example in the SDK  ? ble_app_hrs for example ?

Thank you for your replay,

I run the same firmware in other sensors, there is no issue like a mac address change every time I flash code.

Thanks for the update. It's quite strange that the address changed on your previous sensors. If you see the issue again please let me know.
