| > I've been thinking about bluetooth and a standard protocol and generic app. A long time ago I developed a project called "Handbag[0] for Android"[1] based around a similar concept--it targeted the short-lived "Android Open Accessory Protocol" initially over USB & later also over network/WiFi. (My project notes from the time mentioned a long-term goal of also supporting Bluetooth but that never eventuated...) Handbag made use of a "generic" Android app for UI display/interaction and an Arduino library that communicated with the app over a binary protocol. The app would display various UI widgets such as labels/progress bars to display feedback from the accessory and text inputs/buttons to accept input forwarded to the accessory. While the project did not take the world by storm, I was reminded when digging up these links that at least one person called the concept genius[2]. :) ---- [0] Because it let you "accessorize your Android phone or tablet". :D [1] https://web.archive.org/web/20130205135845/http://handbagdev...
