So I was going some digging and I ran across the nrf24l01. I found it really awesome, and wanted to get some opinions. Would it be possible to hook up an arduino nano, a nrf24l01, and a cell phone to create a communication line between 2 phones? 2 sets of nanos and materials, 1 for each phone, and an app to type in the message. Essentially creating a gotenna but for a much cheaper price. Anyone have any thoughts?
