Hello.
Is it possible to send/get data via wifi hotspot or bluetooth offline (without internet conbection) ?
Develop games in your browser. Powerful, performant & highly capable.
How do you mean? What exactly are you trying to do?
I want to create multiplayer game, but without use internet or server, i want to use buletooth or hotsopt wifi to connect and transfer data between two mobike devices
Look into LAN networking; through the WIFI you have at home, you should be able to connect players without consuming data.
