.. option:: CONFIG_BT_HCI_VS_EXT_DETECT

*Use heuristics to guess HCI vendor extensions support in advance*

Type: ``bool``

Help
====

Use some heuristics to try to guess in advance whether the controller
supports the HCI vendor extensions in advance, in order to prevent
sending vendor commands to controller which may interpret them in
completely different ways.
