Bluetooth: Remove adv set for directed advertising (a9e45698) · Commits · 戴 / test

Extended advertising Data is set during bluetooth initialization by default which causes InvalidHCICommandParameters when setting Extended advertising parameters. As per Core Spec 5.2 Vol 2, PART E, Sec 7.8.53, for advertising_event_property LE_LEGACY_ADV_DIRECT_IND does not supports advertising data when the advertising set already contains some, the controller shall return erroc code 'InvalidHCICommandParameters(0x12). So it is required to remove adv set for handle 0x00. since we use instance 0 for directed adv. Signed-off-by:
