I will likely eventually use Bluetooth in a product dispensing task but, for now, all I need is a single-bit wireless closure to dispense and a single bit response if it's successful.
For a prototype demo I can do it wired but wireless would be more impressive. Is there such a simple link?
Single-bit wireless in both directions

a 'ESP8266' as access point serving a page that could drive one of it's IO back to your app. Not BT, but pretty simple.
