RE: Public vs. Random Static Device Address

I've listed some more reasons at https://stackoverflow.com/a/70181575/556495.

If you want to connect from Android, it has the issue in its API that the address type cannot be set when connecting. It instead uses heuristics to "guess" the address type, which works by checking a list of previously scanned devices as well as bonded devices. If not found, it usually defaults to Public address type.

One good thing with public addresses is that you get an address range for your products which can be nice to have in some circumstances.

Hi,

There is no practical issue with using the default random static address from FICR. With 46 bits, the likelihood of a collision is extremely low (see this post).
