I am starting a task that involves attached and remote sensors being monitored by a Nordic nRF51 (and hopefully nRF52) core. I need to find someone to help with Firmware. I have the nRF51 and 52 dev kits and can run the demo files Nordic provides. As I identify needed blocks of firmware I would like to provide you a description and get a cost estimate then proceed from there. The first block that I need is to be able to connect to an android device and have the nRF51 report temperature on an android app. What would be your estimate to set that up and send me the files so I can test it?
