I am going to be teaching a class and wanted to get one of these projectors. Where I will be teaching, there will not be wifi. I am wanting to just cast it through my iPhone. My lovely Verizon plan has unlimited data but not a hotspot. In saying this, can I connect my phone through bluetooth to the projector and to stream video? Isn’t there a cable I can get for this if the bluetooth isn’t the answer? Also if I can do this will the sound come out of the projector or through my phone? Thanks for the help.
