OHS HCI.py will slowly lose coverage and eventually stop working

[Chapoly1305]

The OpenHayStack HCI.py modifies the Bluetooth adapter's public address to match the generated public key. If you've used the original hci.py or used it as a template for modifications, and recently noticed fewer location reports, here's why:

Since iOS 18.2, iPhones and iPads only accept Find My advertisements from random static addresses.

As Apple rolls out the latest iOS and iPadOS updates, users of hci.py will gradually lose coverage. Additionally, not all adapters support modifying public addresses. Because of this limitation, the original HCI.py only works with specific Broadcom chips used in Raspberry Pi devices. To address this issue, we've developed an improved version that sends advertisements with the correct address type. Like the original version, root privileges are required.
