40 Direction Finding Extension
41 ---------------------------
43 Some radios support the Bluetooth Direction Finding Extension (DFE).
44 The 'dfe-supported' property will be set when it is available.
45 In this case, the 'dfegpio[n]-gpios' properties configure GPIO pins
48 Each dfegpio[n]-gpios property which is set is used to initialize the
51 None of the dfegpio[n]-gpios properties are marked 'required',
56 That in turn means that at least one dfegpio[n]-gpios
