LMP errors is don't to the controller, it has nothing to do with the
host stack where SDP is implemented.

SDP is used only on BR/EDR so the term advertising here makes no
sense, all you need to do is to make the adapter
connectable/discoverable:

bluetoothctl> discoverable on

Don't advertise, BLE doesn't use SDP as it does use GATT to perform
service discovery.
