如何在没有衰减的情况下知道两个蓝牙设备之间的距离？
[英]How to know distance between two bluetooth devices without Attenuation?
问题描述
Is there a way that we can calculate distance between two bluetooth devices without attenuation?
有没有一种方法可以计算两个蓝牙设备之间的距离而不会衰减？ or at least distinguish if the users are close to each other or not?或者至少区分用户是否彼此靠近？
I would like to avoid using attenuation because the bluetooth signal could be deflected or reflected when there is obstacles between devices.我想避免使用衰减，因为当设备之间有障碍物时，蓝牙信号可能会偏转或反射。 And also, I want to avoid using GPS because of privacy problem.而且，由于隐私问题，我想避免使用 GPS。
When I tried to search about this, some people mentioned about response time, but isn't response time would be different if there are obstacles between devices?当我尝试搜索时，有人提到了响应时间，但是如果设备之间有障碍物，响应时间会不会有所不同？
