I am searching for 3 days now, and still I don't find anything that is what I want. Maybe it's not possible? But to accept that, I have to ask here.
I have a project, where I want to exchange usernames to both phones, phone 1 gets username of phone 2 and the other way. I tried many tutorials where NFC Reader is used, but none of them work, like it can't read the sended NFC message or whatever.
I don't really know what's the best way to send a String from phone to phone (which never had a bluetooth or WifiDirect connection, and I don't really want to create that connection).
Do you guys have tips?
