With the gradual widespread application of item locating technology in social life, the market for item locating is growing rapidly. Both Apple and Google have introduced their own Find My protocols, allowing user devices to use this feature for item locating. It works by activating a private and secure finding function through the Find My network, which consists of billions of iOS or Android devices, enabling device locating or item tracking for users.
Realtek's Find My solution, based on the RTL8762 series BLE SoC, offers high integration and excellent power consumption performance. It supports both the Apple Find My and Google Find My protocols. Using the Realtek Find My SDK, customers can quickly develop different product forms tailored to different applications.
System Structure
For Apple Find My tag, Gsensor and buzzer are two essential peripheral components. The typical architecture diagram is as follows:
Practical Application Case
From a technical perspective, Find My tag can support both Apple Find My and Google Find My protocols, enabling the same tag to be located and searched for by both iOS and Android devices. However, in the actual implementation of the solution, how to run the two protocols on the same tag must strictly follow the protocol specifications of Apple and Google.
Advantages of Solution
The MCU is ARM Cortex processor, with optional main frequency of 40MHz ~ 90MHz and optional SRAM 104KByte ~ 192Kbyte. Supports hardware AES/ECC, very suitable for algorithm-intensive application scenarios. Supports Bluetooth 5.0, ultra-low power consumption.
Use one BLE SoC to actualize a single-chip solution, BLE connection and other functions. High degree of integration, extremely reduce the cost of the solution.
The Find My SDK has fully implemented the dual protocols of Apple Find My and Google Find My, which is stable and reliable. Customers only need to do secondary development of application layer functions.
Full-featured SDK/HDK/Tools development kits, with supporting mobile phone APP engineering, which greatly reduces customer's development workload and accelerates the implementation of project.
