目前这个findmy 设备是已经通过MFI认证，不过后续想的在”Find My “应用上像 AirTag 一样支持UWB测距功能。
寻找了相关资料，在这篇文章《Nearby-Interaction-Accessory-Protocol-Specification-Release-R4》中找到了UWB的相关功能，但是需要我们自己开发第三方应用。
所以需要怎么做才可以做到像airtag 一样在“Find My”应用上显示距离和方向
We are currently developing a FindMy device and we're wondering how to use UWB ranging functionality in the "Find My" app.
The FindMy device is currently MFI certified, but we plan to support UWB ranging functionality in the Find My app, similar to AirTag.
After searching for relevant information, I found the relevant UWB functions in this article "Nearby-Interaction-Accessory-Protocol-Specification-Release-R4", but we need to develop third-party applications ourselves.
So how can we make it display distance and direction in the "Find My" app like AirTag does?
To support UWB ranging for a custom FindMy device, you will need to implement a custom app.
