Is anyone aware of an AVR based solution which uses an off-the shelf BT module to link to a smartphone which runs a 'universal' GUI app?
By 'universal' GUI app I mean one where the GUI contents are 'pushed' from the micro to the app, rather than the app being customised for each application.
is was SmartIO from Imagecraft. A few lines of code on the micro defined what widgets appeared in the app and the actions taken, and a bit of code to talk to a dedicated module. (annoyingly I bought a small qty of the SmartIO modules but not enough for any sort of production).
I am aware of solution, which is supplied as a library, which runs on a different uC range and uses a standard BT module. The developer has then published a cross-platform app which is one the various app stores. But it's not AVR.
Basically, I want to avoid having to deal with app development for low volume products and am happy to leave that to someone else.
