    Hi, my application is connecting with several sensors at same time, however during the execution randomly the bluetooth service crashes, and consequently the sensors disconnects on Android Nougat (7.0).
    We have tested several approaches (removing gatt operations (write and reads) and only receive notifications), however the issue continues to happen. Could someone help me with this issue?

    I've attached one log where the issue happens
