I don’t have any experience working with wifi so I would like to ask you a general question.
Lets say that I want a two way point to point data link. I want it to be fast and reliable. There are of course a lot of solutions, e.g. nRf24L01+, BT or XBee. But my question is, can the Spark core be used for this? (Do I have to first upload the data to the cloud and then download it or is it possible to just send it directly to my computer without any detours)
