Hello. Can I connect the core with the cloud, only using the wifi generated by my Iphone and not another external wifi (e.g. my house)? Using tinker it is not possible. May I program some code (i.e. iOS or android in such case) to do that? I think it is called peer to peer communication. Thanks in advance.
sorry for the delay i getting a reply 
You can simply send in your Wifi Credentials via USB and setup a hotspot on your Iphone with the same SSID, Security Type and password.
P2P doesn’t work on CC3000 (i think) and i believe what i mentioned above suits what you need,
Wooola! Done
