If so, > would be great to mention. There are some rare occasion where the link-keys cannot be persisted/stored (e.g. debug keys), but in the other hand Bonded would always means Paired, perhaps this is useful if you want to persist some device information at upper layers otherwise I can't think of any other use of Bonded over Paired. > > + A PropertiesChanged signal indicate changes to this > > + status. > > > > boolean Connected [readonly] > > >
