I need a cheap 2 or 3 button fob or itag to connect to/control my NRF51 firmware. So far I only could find "AB Shutter 3" as input device with >1 button but it is using Bluetooth V3. I'm considering adding the necessary subset of Bluetooth V3 processing to NRF51 to accomplish this but I'm not sure how big of a project that will be. Need something working within a week. Is this reasonably do-able as my first radio device project? Any basic suggestions appreciated. I use Eclipse & armgcc Thanks.
