DEVELOP A PRODUCT LIKE................

Dear, I already worked on similar projects. I worked with bluetooth 4.0, i think it is best suitable for this. I can do and mechanical design of cup, electronic and software for microcontroller. (all) If software engineer work software for microcontroller then cut my price for 600$ so i will do it for 800$. I have many propositions how to make this good way. All the best, Miroslav
