I'm interested in getting a group of iPhones to receive a wireless signal to play music from another source in the same room, essentially acting as a radio receiver.
Originally I imagined that this could be done by transmitting radio waves, but I came to find out that iPhones do not have the ability to receive radio waves built in.
Then I considered bluetooth, but I found out that we can only transmit one bluetooth signal at a time.
Could I do it by hooking up my Pi to my network via an ethernet chord then transmitting it over the local network?
In short, is there a way to send music from my Pi to iPhones without changing each iPhone's system settings (much) that has an advantage over hosting from my computer?
