Should it be `case ADDR_LE_DEV_RANDOM_RESOLVED`? indeed. I have not tested this with static address and identity address yet. This address translation is needed in a few more places. Especially also in the Connection Complete events. And we also need to store the RPA used for the connection since it would be required for SMP. Regards Marcel

When using controller based address resolution, then the new address types 0x02 and 0x03 are used. These types need to be converted back into either public address or random address types.
