BLE scanning and features

[dhje0ng]

The commands below that I use are used to identify LE scans and LE device information via the bluing library.

However, the LE scan does not contain the results of the LE device I want to use and when I send the identification command, I get the following error.

sudo bluing le --ll-feature-set --addr-type=random A8:B9:B3:DF:FD:6C
[INFO] Reading LL FeatureSet of A8:B9:B3:DF:FD:6C on hci0
Reading ✖
[ERROR] bluing.le.le_scan
        HciRuntimeError: "Failed to create LE connection to A8:B9:B3:DF:FD:6C random address
           command status: 0x0c - Command Disallowed
        If this problem persists, restart the Bluetooth service.
        The previous connection was not released properly."

I don't know if this is a library issue or if the target device doesn't support the LE protocol.
Is there any way to check?
