[BlueZ,09/20] tools/mesh-cfgclient: Disallow model commands w/o composition

Commit Message

Stotland, Inga Sept. 23, 2021, 3:25 a.m. UTC

If remote node's composition hasn't been acquired, disallow commands
that change model state (that is, bindings, subscriptions, publications).
Prompt to run "get-composition" command first.
