I’ve been working on a remote keyboard device that can control a phone, with the intention of using it while driving. You can check out my work so far here.
The idea is to use the remote to control the phone while driving so you don’t have to interact with the touchscreen. I’ve developed a simple app that handles the bluetooth connections and demos some simple actions. My background is hardware, not android development.
And if you are a developer with bluetooth experience i’d love to hear your thoughts on my device!
