I can reproduce your compile error in the platformio branch but I couldn’t figure out why the default values in e.g. mbed-os-qmesh/mbed_lib.json at main · faydr/mbed-os-qmesh · GitHub are not showing up in the mbed_config.h, which is the source of the problem. It seems either PlatformIO or mbed is under the impression that the component is not in use. Please file a bug in Issues · platformio/platform-ststm32 · GitHub for the developers. Due to the war, answers will however take a while.
