I've seen in EFR32MG Reference manual that EFR32MG has read only EUI48 identifier consisting of 24 bits Organizationally Unique Identifier and 24 bits unique identifier.
Does anyone knows if second 24 bits (unique identifier) is unique for every EFR32MG piece (like 64 bits device unique number), or something else? Could we use it to distinguish between MCUs in same network?
Once 2^24 of these devices have been manufactured, the Unique Identifier EUI48L[23:0] will effectively roll over and will no longer be unique. However, this can be considered practically unique and acceptable for most applications (for example, the EUI48 can be used as a MAC address). Ultimately, you must evaluate if this is sufficient for your application.
Thanks for your reply. I am aware of rolling over after 2^24 pcs, but I think that for our application it will be OK.
