I cannot use airplay with my iPhone and Ipad with the beamer, anyone has any idea? The beamer's name showed up in my iphone and ipad all the time, and when I clicked the name the first time, both also showed a code. After I entered the code , it just didn't connect, without any words. Afterwards, every time I clicked the beamer's name, it seemed to try to connect for one second, but never succeed. I also tried to use airplay to connect my MacBook with it, it worked. I don't know what might be the issue with the iphone and ipad?
