Hello There, looking for someone to help built a prototype device controlled by smartphone via bluetooth. see it at metertag.com
I can help you with this if you have not yet had any replies. I have already developed a BLE controlled scale for another client called "The barman" that was launched on Kickstarter.
Please take a quick look at my website WWW.EmbeddedAT.com and see if you think I am a good fit for this project.
Feel free to drop me an email to Peter@EmbededAT.com if you have any questions or would like to chat about your requirement a bit further.
