Apple's Find My achieves positioning through a network built with Bluetooth technology and a massive number of Apple devices, while protecting privacy via high-strength encryption—ensuring stable integration of devices into the ecosystem.
When a device is connected to the internet, it uploads real-time location data to Apple's cloud servers via its own Wi-Fi or cellular network connection. After logging into their account through the Find My app, users can directly retrieve the device's precise location from the cloud. If the device is offline, it periodically broadcasts a Bluetooth signal containing a temporary derived public key. Nearby Apple devices (such as iPhones and iPads) that are powered on will detect this signal, encrypt and upload their own location along with the received signal information to Apple's cloud. When the user queries the location, the cloud aggregates and returns this data, enabling the determination of the offline device's approximate position.
Multiple Telink chips are compatible with Apple's Find My communication protocol, serving as the hardware core for third-party devices to access the Find My network. In addition to providing Find My-enabled chips, Telink offers a dedicated SDK and a complete firmware protocol stack. Customers can leverage these resources to quickly implement solutions for production and conduct secondary development to achieve personalized features based on their needs, helping them create different products.
