From: DoHyun Pyun <dh79.pyun@xxxxxxxxxxx> Since BlueZ has ObjectManager interface, ChannelConnected and ChannelDeleted Signals of HealthDevice interface was not available. ObjectManager reports the HealthChannel D-Bus interface when g_dbus_emit_signal function is called, and generates "InterfaceAdded" signal. But ChannelConnected and ChannelDeleted Siganls was not generated. If health-api document contains these signals, application or service using Bluez Dbus API will get the unexpected result. If we just remove g_dbus_emit_signal for ChannelConnected and ChannelDeleted, InterfaceAdded signal will not sent. Because InterfaceAdded signal is pending before sending a dbus signal. These patches include new property in HealthChannel interfacem, and this PropertiesChanged signal can be used to replace the previous ChannelConnected and ChannelDeleted signals.
