Hi Nick, this is correct behavior and is how user privacy is preserved. All you can do is either scan for known Advertised UUIDs or query for known Service UUIDs once connected. Once a peripheral disconnects the CBPeripheral object is pretty useless.

best,
Richard

Does anyone have any idea about this? Should I create a bug report?

When another advertisement packet is received, it checks if the CBPeripheral object has already been discovered previously. My problem is that I am seeing multiple CBPeripheral instances with different identifiers for the same device. Is this correct behaviour? Shouldn’t the identifiers (at least) be constant for each peripheral device?
