how to create a chat app that works without network on wifi

[viv lbo]

hiii all 

i am new to this, and i want to create a chat app that works on wifi, i mean it can work without any network access.

this chat app kind of forms a mesh network to communicate.

already existing apps of this kind are FIRECHAT and also SERVAL MESH.

i have taken inspiration from them.

Wifi usually means network access, and Firechat is (I think) based on Firebase, which also means network access, although you do not see it in your app.

What you could do, is make a Bluetooth chat app. In fact there is already one that you could use as a basis: http://puravidaapps.com/btchat.php

For Bluetooth you do not need internet access, but your phones should be close and they should be paired in advance.

Cheers, Ghica.

Firechat can work peer to peer between phones, which overcomes normal network restrictions.

Not sure if AI2 is up to this sort of thing, but you might be able to do something browser based through the webviewer?

you could write your own extension and create a block yourself...

to use the Nearby API would be great, see also here https://developers.google.com/nearby/

more information about how to create an extension see here https://groups.google.com/d/msg/mitappinventortest/Ip2AX036d0U/5NJlAEbFCgAJ

however that will be more advanced and will require some Java skills...
