I'm building a wearable Bluetooth device. When a button is pressed on the device, it sends a signal to the user's smartphone and consequently an app on said phone. I'm an app developer with no engineering background - but I've been doing plenty of research.
A means of communicating a button press into a message sent to the phone is necessary. I'm told making this from scratch will cost about $30,000 to have a competent engineer design it. I'm trying to find ready made solutions, but am struggling to find a Bluetooth module with an analog input built in which is what I believe I need.
Is there a ready made solution for what I'm doing or some method, tutorial or kit available that I'm overlooking? It seems crazy to me that there isn't, but my research has been fruitless thus far.
