Hi guys.
I want to ask about Sparkfun Photon Redboard. I have a project that will use Sparkfun Photon Redboard. I want to connect this board with my sensor. And send the data of my sensor from this board to smartphone using Bluetooth. As far I search about this board, I have not find about Bluetooth. Is it true that I need to add on bluetooth device on this Sparkfun Photon Redboard? Thanks for your attention.
Thank you.
