How to Scan other Bluetooth devices in android Studio

  • Hello everybody,


    I am not completely new to Android development, but for a few days now I have been trying to develop a Bluetooth app that can scan more devices like in my mobile phone but through my app. All tutorials that I have found so far do not work at all.
    I am already posting my code from the android studio. I can list paired devices, but the scan cannot.


    If someone has a good experience with Bluetooth here, I ask them for help. I thank you in advance
