Hi, I am currently learning how connman plugins work, I started with plugin-api.txt and also looked the sources, then tried to follow the plugin document to get a "proof of concept" going. So far I can see that the init function of my plugin is being called, but that's it. I did register tech, network and device callbacks via connman_network_driver_register(), connman_device_driver_register() and connman_technology_driver_register(), but I do not see any printouts in the callbacks, no probes, nothing. Could someone please explain what needs to be done in order for a technology to become visible? I guess same is valid for "device" and "network". When I look at other plugins (for instance ethernet), the only thing their probes do is to return 0. So how exactly does it work? Am I supposed to use some notification mechanisms that are not mentioned in the plugin documentation or what am I missing? Kind regards, Jin
