Our app provides configuration and maintenance features for Siemens electrical devices. The app supports multiple devices and the devices have their own specific features, which also need to be supported by our App. The devices can be released to the market only when our app supports those features. Our app release timeline is once in every 4 months. We face a challenge when some of these devices are not able to deliver their features by our release time. So, we would like to make these devices plugins, which can be independently released, without releasing the App every time. The app would, of course, be released once in every 4 months, depending on the common features. I'm not able to find how to release only the plugins within the app, without releasing the entire app. Some one has suggested app extensions, but that does not fit our solution as in some cases, we need continuous polling of data from one or mode devices for minutes or hours, as the app can be used by the user to monitor some of the device values.
