When we call the bluetooth BLE manager for connection was success but it is getting unpair and disconnected frequently on android phone.

What I have tried:

fun isDevicePaired(name: String) : Boolean {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
            if (ActivityCompat.checkSelfPermission(
                    context,
                    Manifest.permission.BLUETOOTH_CONNECT
                ) != PackageManager.PERMISSION_GRANTED
            ) {
                // TODO: Consider calling
                
                return false
            }
        }
        lateinit var mBluetoothAdapter: BluetoothAdapter

        try {
            mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter()
        } catch (e: Exception) {
            return false
        }

        var pairedDevices: Set<BluetoothDevice>? = mBluetoothAdapter.bondedDevices

        for (device in pairedDevices?.toList() ?: listOf()) {
            if (!device.name.isNullOrEmpty())
                if (device.name.contentEquals(name))
                    return true
        }

        return false
    }
