JoSeBu :
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.
Thank you

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. Take a look at the official Android docs on BLE. 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
