[英]How to read data from a Bluethooth BLE device without pair in Android
问题描述
I have a Bluetooth device and I need to read data from it but without pairing with it, since it does not allow it, but I do not know how to do it, I know it is possible because I have another application that does it, but I do not know how to display the device data.

Bluetooth works by pairing with a specific device, whereas BLE is more like a community message board, with devices posting little pieces of information or accepting small updates.蓝牙通过与特定设备配对来工作，而 BLE 更像是社区留言板，设备发布少量信息或接受小更新。 Take a look at the official Android docs on BLE.查看有关 BLE 的官方 Android 文档。 They describe the basics of the protocol and outline how to discover devices and perform read/write operations: https://developer.android.com/guide/topics/connectivity/bluetooth-le他们描述了协议的基础知识并概述了如何发现设备和执行读/写操作： https : //developer.android.com/guide/topics/connectivity/bluetooth-le
